RBOSP Progress Report 2 - Summary described the Geotechnical Data Gathering Project in detail. The major activity during this reporting period for the Geologic Program involved the correlation, interpretation and refinement of data for input to the DDP. The rock me- chanics testing has been completed; however, a report containing the results of the rock mechanics tests has not at present been completed. The other tasks of the Geologic Program are for the most part complete. A status of each of the tasks of the Geologic Program are presented in the following sections. Activity under the Hydro! ogic Program included the hydrologic baseline data gathering tasks as well as interpretation of the pumping test data. The Hydrologic Program has been slightly modified in that section 1.2.9, Dewatering Analysis has been removed from the Hydrologic Program scope of work and added to the scope of work of the engineering studies. The dewatering analysis will be reported in the DDP. Section 1.2.8, Data Input to Mathematical Model, has been redesignated Hydrologic Program - Summary and Analysis. The data from the Hydrologic Program is submitted to the Area Oil Shale Supervisor in the following parts of RBOSP Progress Report 4: Interpretive Text, Interpretive Text Appendix, and Raw Data. CO m o 1 .1 Geologic Program Most of the tasks conducted under the Geologic Program are essentially complete. Confirmation oil shale assaying of some of the oil shale core intervals of coreholes G-S 4-5 and G-S 6 indicated that some of the sample intervals from these coreholes would have to be reassayed as the confirmation testing disclosed some discrepancies. Rock mechanics testing has been completed; however, the final report on the results of the rock mechanics testing is still being written. The following sections up date the status of each of the tasks. GO m o > 1.1.1 Corehole Program The corehole program is complete as reported in RBOSP Progress Report 2 - Summary. The drilling locations have been graded and fenced prior to seeding in the fall as requested by the Area Oil Shale Supervisor. go m O rx) 1.1.2 Laboratory Analysis All laboratory analyses have been completed. The results of the laboratory analyses for oil shale grade, nahcolite, extractable alumina, gas and trace elements have been reported to the Area Oil Shale Supervisor. The report of the results of the rock mechanics testing is still being written. It is anticipated that the rock mechanics data will be submitted in RBOSP Progress Report 5. During the quarterly reporting period correlation of oil shale assay data with respect to stratigraphy showed unexpected differences in assay results of the lower portions of two coreholes, G-S 4-5 and G-S 6. Subsequently a total of 45 confirmation assays were run on samples from these two core- holes. A significant disagreement between the results of the original assay of the core samples and the rerun assays of the same core samples was detected. As a result, core intervals in the lower portion of both coreholes G-S 4-5, and G-S 6 are being re-assayed. The results of the re-assays will be reported in the appropriate (timely) progress report. m o co > 1.1.3 Strati graphic Compilation The strati graphic compilation has been completed as reported in RBOSP Progress Report 2 and updated as reported in RBOSP Prgress Report 3. There has been no new activity to report in RBOSP Progress Report 4. > GO m o > 1.1.4 Aerial Photography Arrangements have been made for aerial photography of an additional 8200 acres covering the 84 Mesa area north of Tract C-a. The photography will be used in the detailed topographic mapping of 84 Mesa. > I m o 1.1.5 Compilation of Topographic Maps New topographic mapping of approximately 8200 acres in the 84 Mesa area will be compiled after black and white aerial photography has been completed. > CO m o CX> > 1.1.6 Photogeologic Mapping Photogeologic mapping has been completed as reported in RBOSP Progress Report 2 and RBOSP Progress Report 3. GO m o > 1.1.7 Surface Geologic Mapping The surface geologic mapping of about ten square miles was completed as reported in section 1.1.7 of RBOSP Progress Report 2. > I I m 00 1.1.8 Seismic Program The seismic program was discontinued as reported in section 1.1.8 of RBOSP Progress Report 2. > CO m o <£> 1.1.9 Structural Compilation Two additional faults have been observed in the northwest corner of Tract C-a. Several other fault interpretations were changed to a minor degree. A middle A-groove structure map is being revised accordingly and will be submitted as a part of the DDP.

RBOSP Progress Report 2 presented the hydrologic data obtained during the corehole drilling program. RBOSP Progress Report 3 presented the data collected during formal pump testing. This progress report will present continuing data collected from the hydrologic monitoring program, data from the drilling of monitor hole 5, as well as hydrologic interpretive analyses. Interpretive informa- tion based on data collected to date in this report includes recharge and leakage effects, permeability, apparent velocities, piezometric levels, transmi ss i vi ty areal plots and Theis and Jacob plot analysis. In addition, areal distribution of selected chemical constituents are also plotted. RBOSP Progress Report h submits the data generated from the Hydrologic Program to the Area Oil Shale Supervisor in two parts. Those parts are: 1) Interpretive Text, and 2) Raw Data. The Interpretive Text contains interpretation and explanation of the hydrologic data while the Raw Data portion contains computer print- outs of the raw field data. The raw field data was digitized for ease of storage and recall and to provide input to various com- puter programs. Hydrologic data collection began with the drilling and coring operations by RBOSP in July 197^. Previous hydrologic baseline data collected in the area is contained in "Phase II, Preliminary Dewatering Analysis Report, Cameron Engineers, November, 1972" and "Phase II, Preliminary Hydrogeol og i c Report for AMOCO, December, 1973," and RBOSP Progress Reports 2 and 3, Section 1.2 Hydrologic Program. Wright Water Engineers, Inc., Denver, Colorado has been compiling the hydrologic data on behalf of RBOSP. -1- RBOSP PROGRESS REPORT CO m o rsa 1.2.1 SURFACE WATER MONITORING STATIONS As part of the environmental baseline monitoring program, RBOSP has contracted with the Colorado River Water Conservation Dis- trict to have Water Resources Division of the USGS construct 11 surface water monitoring stations. Six of these stations have been in operation since March of 197**. The Rinky Dink Gulch Station has been in operation since November 197**. The four new gaging stations monitoring the 84 Mesa area are presently under construction, however, it should be noted that monitoring has been carried out for the past several months. Table 1.2.1 gives the USGS identification number and location for the 11 surface stream gaging stations and the 6 rain gaging stations. Table 1.2-2 shows the data collection schedule for the 11 stream gaging stations. It should be noted, however, that, to date, continuous temperature and specific conductance data have not been received from the USGS. In addition, we are also waiting to receive the sediment discharge data for 1975 which we under- stand will be forthcoming at the end of the water year. The results of the data collection program are in Section 1.2.2 of this report. -2- RBOSP PROGRESS REPORT CO m o rv> TABLE 1.2-1 LOCATION AND USGS IDENTIFICATION NUMBERS FOR SURFACE AND RAIN GAGING STATIONS USGS Ident i f icat ion Number Location 09306237 Dry Fork near west line Tract C-a 09306235 Corral Gulch near west line Tract C-a 09306240 Box Elder Gulch near west line Tract C-a 09306242 Corral Gulch east of Tract C-a 09306230* Stake Springs Draw near confluence with Corral Gulch 09306255 Yellow Creek near White River, Colorado 09306241 "Rinky Dink" Gulch near east line Tract C-a 09306248 Upper Big Duck Creek north of 84 Mesa 09306250 Lower Big Duck Creek north Of 84 Mesa 09306246 Tributary to Yellow Creek east of 84 Mesa 09306244 Corral Gulch south of 84 Mesa Rain Storage-Type Gages 09306235 Corral Gulch near west line Tract C-a 09306237 Dry Fork near west line Tract C-a 09306240 Box Elder Gulch near west line Tract C-a Recording Rain Gage 09306230 Stake Springs Draw near confluence with Corral Gulch 09306255 Yellow Creek near White River, Colorado No number Cathedral Bluffs located in NW 1/4, NW 1/4, Sec. 14, T2S, R100W "Given incorrectly in RB0SP Reports 2 and 3 3- REOSP PROGRESS REPORT TABLE 1.2-2 DATA COLLECTION SCHEDULE FOR STREAM GAGING STATIONS CONTINUOUSLY OR AUTOMATICALLY Flow Rate Sediment Discharge Temperature Specific Conductance PERIODICALLY Storage Rain Gages Recording Rain Gages SEMI-MONTHLY Water Samples Analyzed for Bar i urn Boron Calci urn Chromium (Hexavalent) Copper Fl uor ide I ron L i th i urn Magnes i urn Potass i urn Selen i urn S i 1 i ca Sod i urn Sulfate Zinc Ammon i a Bi carbonate Carbonate Chloride Color Di ssol ved Sol ids Kjeldahl Nitrogen Nitrate Nitrite Odor Oi 1 and Grease Turb id i ty Dissolved Oxygen pH Arsenic Cadmi urn Lead Manganese Mercury Total Phosphate Ortho Phosphate Cyanide Su 1 f i de QUARTERLY Sample and Analyze: COD Fecal Col i form Pest i cides Polycyclic Aromatics Rad ioact i vi ty Gross Alpha *» picocuries/1 Ra226 Gross Beta 100 picocuries/1 Th230 Uran i urn Spectrographic Scan 67 Elements TOC 10 mg/1 DOC SOC Phenol s Su I fur Ni trogen k- RBOSP PROGRESS F MtfK etc K'VER Figure 1.2- 1 STREAM GAGING STATIONS Rain Gaging Stations and Alluvial Aquifer Monitoring Holtt *-*— Surface Water Gaging Station o — Storage Type Rain Gage » - Recording Type Rain Gage • —Alluvial Aquifer Test Wells 8 T I -5- RBOSP PROGRESS REPORT GO m o 1.2.2 SURFACE WATER DATA COLLECTION The surface water data received by RBOSP, collected in 1972*, are presented in RBOSP Reports No. 2 and 3.

The first samples were collected June 12, 1975. With the exception of the four 84 Mesa gaging stations, only four stat ions recorded any discharge during the period beginning in May and ending in August 1975. These four stations are Corral Gulch and Box Elder Gulch near the west line of Tract C-a, Corral Gulch east of Tract C-a and Yellow Creek near the White River. Tables 1.2-3 through 1.2-6 show the amount of the various chemical constituents as reported by the USGS during this period. It should be noted that these data are preliminary and therefore subject to corrections and revisions. As of this date, RBOSP has yet to receive data from the continuous moni- toring of temperatures and conductivity from the USGS. This data will be reported when it is received. As previously noted, the first runoff event for the 84 Mesa gaging stations occurred June 12, 1975- Since this time, several other runoff events have occurred, however, at this time, the data have not been reported to RBOSP. It is anticipated that the information will be available for the next quarterly report. Review of the USGS instantaneous discharge conductivity, boron and fluoride data for May through August was made for the gaging stations at Box Elder Gulch, Corral Gulch east of Tract C-a and west of Tract C-a, and the station on Yellow Creek near the White -6- | RBOSP "PR0GRESS~REP0RT" River. The Box Elder Gulch Station recorded flow only during May and June 1975 having an average instantaneous discharge of 0.5 cfs. Discharge at Corral Gulch east of the Tract dropped back to a median level of about 1.2 cfs after reaching a rela- tively sudden high of 3 cfs in May due to spring runoff. Corral Gulch west of the Tract recorded a saml 1 and broad increase and decrease from mid-May through mid-July. A peak of about .2 cfs in late June was reached from a previous base of less than .01 cfs. The last recorded value of .1 cfs indicated a trend back to a barely detectable amount. Discharge in Yellow Creek near White River has been more variable with a low of about 1.1 cfs being reached after a down trend from a peak of 3-3 cfs. A somewhat strong increase which reached 1.7 cfs in mid-July occurred from the low in June. Thereafter, a rapid return to the low of 1 . 1 cfs was recorded. Conductivity, as recorded by the USGS for the four stations men- tioned, presents a relatively stable picutre. At Box Elder Gulch, conductivity ranged from 800 to 750 umhos/cm. At Corral Gulch west of the Tract, a slight drop from 1100 to 980 umhos/cm occurred in late May. A recovery to the former value of 1100 took place from May through July. Corral Gulch east of the Tract has been on a downward trend from a late May value of 1500 umhos/cm to a late July recording of about 1100 umhos/cm. Yellow Creek values have been most variable and consistently highest with a peak value being reached in late June of ^200 umhos/cm from a low of 3000 umhos/cm in late May. July values indicate a downward trend to 3500 umhos/cm near mid-month and then an upward trend to khOQ umhos/cm in mid-August. Boron values have been stable and close to the corresponding median values in Yellow Creek, .7 ppm, and Corral Gulch (.1 ppm) west of the Tract. In Corral Gulch east of the-Tract, boron values fluctuated from .2 ppm to .7 ppm in April and May with a fairly stable trend at 0.16 ppm indicated from mid-June to late -7- RBOSP PROGRESS REPORT July. Boron concentrations in Box Elder Gulch decreased from 1.0 ppm in May to 0.7 ppm in late June. Fluoride in Corral Gulch west of the Tract has been stable at •3 ppm from late May through July. Yellow Creek values fluctu- ated from 1.8 ppm to 2.5 ppm during the same period. Corral Gulch east of the Tract has had wide fluctuations. A low in mid-May of .'4 ppm was rapidly replaced by a value of 2.8 ppm in late May. A sudden decrease to .5 ppm occurred by mid-June. Thereafter, through late July, a relatively stable .5 ppm value has been reported, Box Elder Gulch fluoride values are 0.3 ppm. Examples of constituents that increase in concentration by orders of magnitude from gaging stations around Tract C-a to the gaging stations at the mouth of Yellow Creek include alkalinity, barium, boron, bicarbonate, chloride, sodium and sulfate. Conductivity and total dissolved solids also increased at least four times. Summary water analyses for stream gaging stations at Box Elder Gulch, Corral Gulch west and east of the Tract, and Yellow Gulch are presented in Table 1.2-3 through 1.2-6. Upon comparison of samples taken on or near Tract C-a to that of the station at Yellow Creek near White River, water quality varies substantially. In general, stream flows from the Tract pick up their contaminants along their way to the mouth of Yellow Creek, and the water quality deteriorates with increase in surface flow distance. During the pumping tests of the upper and lower aquifers, dis- charge water contributed to the flow of existing streams. Water from the pumping tests infiltrated into the stream beds and dis- appeared within a maximum distance of k miles from the point of discharge. Discharge water for G-S D 1 7 which was pumped at 275 gpm -8- RBOSP PROGRESS REPORT flowed down Dry Fork into Corral Gulch and past the hunting club, but did not reach the road ]/k mile above Tract Head- quarters at G-S D 1 8 (Figure 1.2-10). During the pumping period in January there was considerable build-up of ice on the road in Dry Fork to G-S D'l7 due to freezing of discharge water. G-S D16 was pumped at 123 gpm (0.27 cfs). The discharge entered Box Elder Creek just below the upper Box Elder Creek Flume and joined natural flow in the creek (less than 0.05 cfs discharged from a spring 50 feet above the flume). The combined flow dis- appeared approximately ]/k mile above G-S D 1 9 - Discharge from pumping CE-705A on the G-S D 1 9 location at 264 gpm (0.59 cfs) did not reach the area of the lower flume on Box Elder Creek (Figure 1.2-10). The first pumping test of G-S D 1 9 at 667 gpm (1.^9 cfs) resulted in a flow of 1.17 cfs at the lower Box Elder Gulch flume and an increased flow of 0.9 cfs at the USGS gaging station on Corral Gulch at the east edge of the Tract. Before pumping began, Box Elder Gulch from G-S D 1 9 downstream was dry. The USGS gaging station had flow due to a spring above it. The data from the two Wright Water Engineer's flumes on Box Elder Gulch and the Water Resources Division of USGS flume above 8k Ranch which were monitored daily and the provisional continuous flow data from the USGS gaging station east of the Tract are shown in Figure 1.2-11. During the second test of G-S D 1 9 flume readings were affected by stream runoff from above the discharge point as seen in the upper Box Elder Creek flume. The pumping of G-S D 1 9 does not appear to have had any affect on the flows at the flume near the Sk Ranch. The drop in readings of the Sh Ranch flume after May 27, 1975 af^ due to flow being diverted to an irrigation canal directly above the flume. There was not flow in Corral Gulch at its junction with Stake Springs Draw during any of the pumping. ■9- RBOSP PROGRESS REPORT ~i There are two types of precipitation gages used for col- lecting data by RBOSP. The first type is known as a storage precipitation gage. Precipitation is collected and measured periodically, therefore, this type of gage only gives information as to how much precipitation has fallen during the period. The second type of precipitation gage is the recording type gage. This equipment allows the measurement of precipitation over a much shorter period of time, therefore, rates of precipitation, such as inches per hour, are measured. Precipitation recorded by storage type rain gages from January through July, 1975, shows the amount of rainfall during the period. Figures 1.2-12 through 1.2-14 are plots of precipi- tations. Average storage rain recorded on the Tract was 0.5 inch. Both Dry Fork and Corral Gulch indicated peak amounts occurred in May, while the Box Elder Gulch Station reached its maximum between March and April. This indicates localized rain showers are prevalent. Correlation between stations indicates a dry period in early July, in which time no rainfall was recorded in Dry Fork and Box Elder Gulch Station, and below average rainfall was measured at Corral Gulch Station. Precipitation collected by recording rain gages from January through May 1975 are described in Progress Report 3- During the time period from June to July, there were no records from the precipitation gaging station near Cathedral Bluff because of equipment malfunction. Correlation between the gaging station at Stake Springs Draw and the station on Yellow Creek near White River indicates there was less instantaneous moisture 10- fm RBOSP PROGRESS REPORT fall during June as compared to May. Instantaneous peak amounts to date this year were recorded by these stations in mid-July with 1.19 inches recorded in a 2k hour period at Stake Springs Draw gaging station. During this same period of time, the Yellow Creek Station recorded about .48 inches. This variation in amounts between stations indicates that local thunker showers were prevalent over the area. Figures 1.2-12 through 1.2-20 show precipitation data avail- able to date. -11- RBOSP PROGRESS REPORT TABLE 1.2-3 SUMMARY WATER ANALYSIS STREAM GAGING STATION, USGS 09306235 CORRAL GULCH NEAR WEST LINE TRACT C-a 3/12/75 3/16/7, 4/9/7' 4/23/7! 5/14/7/ 5/28/75 i/ 1 1/75 6/24/7 i7/15/7( 1.

Additional information is also included in RBOSP Progress Report No. 3. Those holes which encountered water (G-S S7, G-S S8, G-S SI 1 , and G-S S12) were fitted with continuous (Stevens, Type F) water level recorders. Table 1.2-7 is a summary of the water quality data from samples of the alluvial aquifer to date. Water quality information from the four "wet" holes (G-S S7, G-S S8, G-S Sll, and G-S S12) covering March, April and May is presented in RBOSP Progress Report No. 3- A program involving the drilling of eight additional alluvial water monitoring holes began on June 18, 1975- The holes were drilled to obtain subsurface hydrological and environmental base- line data around 8*4 Mesa. The drilling program was completed on July 16, 1975- Figure 1.2-1 shows the locations of alluvial moni- toring holes. Of the eight holes drilled, only four encountered water (G-S S19, G-S S22, G-S S23, and G-S S24) . The first water samples for these four monitor holes were collected on June 30, 1975. The analyses of these samples are shown in the Raw Data Volume, Section 1.2.3. Figures 1.2-21 through 1.2-28 show the static water levels, conductivity, temperature and pH of alluvial holes versus time. The ground water geologists field reports is included in the Appendix of this report. A 5-1/2-inch O.D. Becker Hammer was used for drilling the alluvial holes. One advantage of using the Becker-Hammer method is the con- tinuous recovery of clean formation samples. Two-inch inside diam- eter plastic casing perforated with bandsaw cut slots over the en- tire aquifer interval was installed in each hole. The annulus was then backfilled with washed gravel. Five feet of 7_inch O.D. steel pipe was cemented to the hole as surface casing. Thread ■35- I RBOSP PROGRESS REPOF protector caps were installed to protect holes from contamination The thickness of the alluvium ranged from 12-20 feet in the small tributary holes to around 90 feet for Duck Creek and the tributary to Yellow Creek alluvium. The alluvium consists of clay, silt, fine sand and rock fragments derived from the Uinta Formation and the Parachute Creek Member of the Green River Forma- tion. The lower part of the alluvium at Duck Creek and Yellow Creek contains more and coarser gravel than the small tributary alluvium drilled at G-S SI 5 , S-G S16, S-S SI 7 and G-S SI 8. The tributary deposits consist of colluvial and alluvial fan deposits. Water quality measured during the drilling program indicated the following ranges: temperature 10.5 to 12.1 C, specific conduc- tance 1910 to 2275 umhos/cm, and pH 6.8 to 7-0. The water level increases during May and June in the alluvial holes are thought to be due to infiltration of increased runoff from snowmelt. The magnitude of the increase varied depending upon the drainage system in which the hole was located. The water level in alluvial hole G-S S7 on Corral Gulch at the western edge of the Tract has declined since monitoring began in January, 1975, with the exception of approximately two foot in- crease during June 1975- The water level in alluvial hole G-S S12 has declined slightly since January 1975 with approximately 1/2 foot increase in May and a 3A foot drop at the beginning of July. Water levels in alluvial holes G-S S8 and G-S SI 1 increased over 5 feet during May. The associated Box Elder Gulch had flow during this time. The increase in water level in G-S Sll in April is probably due to recharge by the discharge water during the G-S D19 pump test. -36- RSOSP PROGRESS REPORT G-S S24 had declined less rapidly from June 30 than either G-S Sll or G-S S8. Its water level is approximately that of Corral Gulch and could not have risen above its present value without discharging to Corral Gulch. A similar small decrease in water level occurred in G-S S22. Water levels in the Duck Creek alluvium have declined from June 30 when the first readings were obtained. The alluvium of Dry Fork at G-S S6 is unsaturated. Also the alluvium of Rinky Dink Gulch is unsaturated as determined from G-S SI 3 and G-S Sl4. The alluvial aquifers appear to be intimately tied to the surface water system. The alluvium receives recharge from stream when the water table is below stream level and contributes to springs and surface flow when the water table intersects ground surface. The water level responses in the alluvial holes indicate the greatest source of recharge is snowmelt on Cathedral Bluffs. Water level changes appear to dissipate downstream due to valley widening and attenuation of the crest. Field measurements of water quality, conductivity and pH were made as part of the water quality study of the alluvial aquifer (see Figures 1.2-21 through 1.2-36). Conductivities ranged from a low of 860 in G-S S8 to a high of 2275 in G-S S23- For individual holes, conduct ivi tes have been relatively stable with a slight in- crease and decline during June and July. The decline in conduc- tivity has been associated with constant to slightly increasing values of total dissolved solids (TDS) indicating a change in com- position. Conductivity is an approximate indicator of TDS. The conversion factor to TDS from conductivity is x 0.72. The high -37- RBOSP PROGRESS REPORT] j conversion factor is due to the large sulfate content. Changes in conductivity may indicate changes in composition and not changes in TDS. The pH of the alluvial water is generally slightly acidic with a range of 6.0 to 1.2 with an average of 6.7- Most holes fluctuate between 6.0 and 6.8. Temperatures have ranged from 7-5 to 13-5 C. Water temperatures increased from March through early July and then declined with the exception of G-S S7- During the summer months, temperature fluc- tuations of 2 C are observed which may be caused by rapid warming of the sample during hot days. Individual wells show considerable change in major components, some may double, from one sample to the next though TDS remains relatively stable. Maximum, minimum and average values for wet chemical and spectrographic analysis are presented in Tables 1.2-7 and 1.2~7a. The average values except for fluoride are slightly higher than those of the upper aquifer. The carbonate ion present in some analysis are not present in the alluvial water, but represent changes in carbonate equilibrium with an increase in pH to over 8 by the time the analysis was performed. 38- R30SP PR . . jrt ID TABLE 1 .2-7 WATER QUALITY ANALYSIS SUMMARY WET CHEMICAL ANALYSIS ALLUVIAL AQUIFERS No. Items 1 tern Low High Average 469-308 Averaged Alkal ini ty 329.000 615.000 49 Al umi num < 0.100 < 0.100 0.0 4 Ammon i a < 0.100 1 .000 0.287 39 Arsenic < 0.010 0.010 0.000 49 Bar i urn < 1 .000 < 1 .000 0.0 49 Bi carbondate 370.000 750.000 566.735 49 Boron < 0.010 27.000 1.783 49 Cadmi um < 0.010 0.090 0.009 49 Cal ci urn 28.000 210.000 99.163 49 Carbonate < 0.100 54.000 5.510 49 Chloride 6.800 71 .000 17.698 49 Chromi um < 0.050 < 0.010 0.0 49 Conductance 860.000 2370.000 1565.518 49 Copper < 0. 100 0.300 0.033 49 Cyan i de < 0.010 0.010 0.001 49 Di ssol ved Sol ids 6A0.000 1670.000 1134.592 49 Fl uoride < 0.100 0.800 0.333 48 Gross Alpha 1 .400 17-000 8.764 28 Gross Beta 1 .000 12.000 6.250 4 Hardness 280.000 765.000 570.816 49 Hydroxi de -- -- 0.0 0 1 ron < 0.050 28.000 8.018 49 Lead 0.020 0.800 0.214 49 Li thi um -- -- 0.0 0 Magnes i um 3.700 874.000 94.939 49 Manganese < 0.050 14.000 2.298 49 Mercury < 0.010 0.002 0.000 49 N i ckel 0.010 0.200 0.049 49 Nitrate < 0.100 21 .000 5.106 49 pH 6.000 7.200 6.665 49 Phosphate < 0. 100 0.200 0.010 49 Potassi um -- __ 0.0 0 Sel en i um < 0.100 < 0.010 0.0 49 Si 1 i con Dioxi de 22.000 44.000 32.327 49 Si 1 ver < 0.100 0.070 0.003 49 Sod i um 75.000 310.000 191.531 49 Sul fate 1 45. 000 780.000 423.877 49 Sulfide -- -- 0.0 0 TOC 7.000 100.000 33-100 20 Zi nc < 0. 100 5.700 0.625 48 -39 RBOSP PR TABLE 1 .2-7a SUMMARY OF QUALITATIVE SPECTROGRAPH I C ANALYSIS ALLUVIAL AQUIFERS tem Low High Al uminum Ant imony Arsen i c Bar i um Beryl i um Bi smuth Boron Cadmi um Cal c i um Cer i um Ces i um Chromi um Cobol t Col umb i um Copper Dysprosi um Erbi um Europi um Gadol i n i um Gal 1 i um German i um Gold Han i um Ho 1 m i um I nd i um I r i d i um I ron Lanthanum Lead L i thi um Lutet i um Magnes i um Manganese Mercury Mol ybdenum Neodymi um Nickel Osmi um Pa 11 ad i um P 1 a t i n um 0.050 0.001 0.000 0.001 0.010 0.001 0.001 0.001 0.500 0.100 0.500 99999-000 99999.000 0.001 0.000 0.010 0.100 0.001 0.100 999999.000 99999-000 0.001 0.100 0.050 No. Items Average Averaged 0.161 9 0.0 0 0.0 0 0.0 0 0.0 0 0.0 0 0.267 9 0.0 0 0.0 0 0.0 0 0.001 1 0.000 1 0.0 0 0.0 0 0.004 8 0.0 0 0.0 0 0.0 0 0.0 0 0.0 0 0.0 0 0.0 0 0.0 0 0.0 0 0.0 0 0.0 0 0.044 9 0.0 0 0.001 3 0.042 5 0.0 0 0.0 0 0.017 9 0.0 0 0.016 8 0.0 0 0.0 0 0.0 0 0.0 0 0.0 0 •40- buor .

The conversion to a monitor hole was completed on July 1, 1975. G-S M5 was drilled to provide information about the subsurface hydrology of the upper most aquifer system, and for ongoing water quality sampling and water level monitoring. Hydrologic data col- lected during the drilling included water production, water quality and electric logging information. Water production and quality were referenced to drilling depth by a drilling time log. Air rotary equipment was used to drill G-S M5 . Air for circula- tion was provided by two compressors capable of 500 cfm and 600 cfs respectively. Both units are rated at 120 psi. An air mist con- sisting of water and soap injection was not used. An 8~3A"inch unit bit was used to drill the first 70 feet for surface casing, and 4-3A- inch bits were used from 70 feet down to total depth, 907 feet. A G-S M5 well cross section is shown on Figure 1.2-37. 1.2.4.1 Terms Used The following definitions of the terms will be helpful to the reader not familiar with hydrologic reports. 1. Aquifer: A stratum or zone below ground level that contains sufficient saturated permeable material to yield significant quantities of water to we 1 1 s or springs. ■57- RBOSP PROGRESS REPORT 2. Discharge: The rate of flow from the test hole in gallons per mi nute (gpm) . 1 cubic foot per sec. (cfs) = kkS gpm 1 barrel per hour (bph) = 0.70 gpm 1 gallon per min. (gpm) = 1.^3 bph 1 barrel = kl gal Ions 3. Drawdown: The decrease in the static head of water of the aquifer due to pumping. k. Specific Capacity: The discharge from the testhole divided by the drawdown (gpm/ft.). 5. Coefficient of Permeability: The rate of flow in gallons per day through a one square foot cross-sectional area of the aquifer under a hydraulic gradient of one foot per foot (gpd/ft2). 6. Coefficient of Transmi ss i bi 1 i ty : The rate of flow in gallons per day through a vertical strip of the aquifer one foot wide extending the full saturated height of the aquifer under a hydraulic gradient of one foot per one foot (gpd/ft.) 7. Coefficient of Storage: The volume of water released or taken into storage, per unit surface area, when the head on the aquifer is changed by one unit: or the amount of water released from one square foot column of saturated aquifer, in place, when the head on this column is reduced by one foot. The coefficient of stor- age is referred to as the specific yield or drainable porosity for water table conditions in an aquifer. 8. Artesian Condition: The condition where the piezometric water level is higher than the top of the aquifer, that is, water pressure within a confined aquifer causes water to rise, in a test hole, above the top of the aquifer. 9. Water Table Condition: The case where the water level is equal to or lower than the top of the aquifer. ■58- RBOSP PROGRESS REPORT > 1.2.4.2 Water Production A 6-inch Parshall flume was installed on June 29 prior to encoun- tering significant water from G-S M5 . The flume had to be in- stalled far enough away from the rig to catch the combined runoff from both the wellhead and the blooey line. The weathered ground surface is quite permeable and an unknown quantity of the water was lost before it could reach the flume. (See Figure 1.2-38). Water was encountered just before 280 feet. Using the rig's air, discharge tests produced approximately 3 gpm. From 309 to 311 feet and 394 to 396 feet, there was some indication that a little more water was encountered, perhaps 1 to 2 gpm total addition. Water production increased to maximum of 17 gpm after 846 feet, then remained fairly steady to about 895 feet. Water production increased again from 895 to 907 feet (TD) where a connection was attempted. During the two minutes it took to make the connection, the water level rose too high for the air compressors to eject the water from the hole and regain circulation. In order for this situation to occur, a borehole infiltration rate of about 127 gpm is necessary. This indicated initial contact with the upper most major aquifer zone determined from previous tests in Tract C-a region. Drilling was consequently halted at 907 feet as the purpose of the hole at this time is to monitor the water condition of the upper most aquifer. 1.2.4.3 Water Qua! ity Conductivity, pH and temperature were measured during drilling ot G-S M5. (See Figures 1.2-38 and 1.2-39). Conductivity jumped to 4800 umhos/cm, then decreased to 2200 umhos/cm shortly after water was encountered. Thereafter, conductivity gradually decreased to 1400 umhos/cm at total depth. The pH remained relatively stable -59- RBOSP PROGFI £ throughout the drilling, ranging from 6.8 to 7-0. Temperature remained between 55 and 59 F until reaching the increased water producing zone at 800 feet, after which the temperature dropped to hS F and then recovered to 50 F at total depth. A water sample was analyzed for both standard wet chemical and spectrographic analyses. The results of the wet chemical analysis are shown in Table 1.2-8. 1.2.4.4 Geophysical Logs After drilling of G-S M5 , geophysical logs were run. An elec- tric sp-resisti vi ty log was run between a depth of 254 feet, the fluid level, and 903 feet. A Gamma-ray-density log was run from total depth, 907 feet, to a depth of 50 feet where the surface casing ended. -60- RBOSP PRO TABLE 1.2-8 WATER QUALITY ANALYSIS DRILLING G-5 M5 SAMPLES DATE DEPTH TEMP.

The general construction of the monitor well G-S M5 is given in Figure 1.2-37- However, the completion procedure as approved by the Oil Shale Supervisor allows monitoring of the shallowest and is as follows: a 2-3/8-inch tubing, perforated from 250 feet to 280 feet, to monitor the shallowest aquifer that has two tubing disks welded to seal the bottom annul us, was run down the hole and cemented. This completion procedure allows for conversion of the hole for monitoring water from the major "upper" aquifer zone. This can be done by sealing off the perforations from 250 to 280 feet with cement under pressure. Residual cement and sand overlying the upper disk can be cleaned using a 1-inch or smaller pipe and water circulation. Then the tubing disks can be knocked out and the hole can be cleaned using circulation. A bailing test was conducted on July 16, 1975 to make sure that the water bearing zone was open to the well. The static water level was measured first, then five gallons of water were bailed out of the hole with a stainless steel sampler which holds slightly more than 1/2 gallon. The static water level was mea- sured again and only a slight change was noted. Five gallons of water is enough to lower the water level inside 2-3/8-inch tubing by 30 feet with no recharge. Therefore, it was determined that hydrologic connection with the aquifer was achieved. A water sample was taken after the conclusion of the bailing test and entered into the sampling and monitoring program being con- ducted by Wright Water Engineers, Inc. for the Rio Blanco Oil Shale Project. (See Table 1.2-8). Pumping tests were not con- ducted on G-S M5 . ■65- RBOSP PROGRESS REPORT 1 GO m o en TABLE 1.2-9 DRILL HOLE COMPLETION SUMMARY Thi rty On-Tract Ho 1 e s Drill Hole Complet ion Drill Hole Am k Compl et ion G-S 1 U & L P & A G-S 2-3 U & L CE-701 Upper Aqui fer Pump Test G-S 4-5* U & L* CE-702 U & L G-S 6 U & L CE-703 PSA G-S 7 P & A CE-705-A Upper Aqui fer Pump Test G-S 8 Lower Aquifer Only CE-707 U & L G-S 9 U & L CE-708 U S L G-S 10 U & L CE-709 U & L G-S 11 U S L TO 1 U & L G-S 12* U & L* TO 2 U & L G-S 13 U & L TO 3 U & L G-S ]k PSA G-S D16 Upper Aqui fer Pump Test G-S 15 U & L G-S Dl 7 Upper Aqui fer Pump Test Am 2-A U & L G-S Dl 8 Upper Aquifer Pump Test Am 3 U & L G-S D19 Upper Aqu i fer Pump Test Five Off-Tract Holes Drill Hole Complet ion G-S Ml U & L G-S M2 U S L G-S M3 U S L G-S Hh U S L G-S M5 SA Totals Completions in Upper and Lower Aquifers Completions in Upper Aquifer Only Completions in Lower Aquifer Only Holes Plugged and Abandoned Total Number of Holes 22 k 5 35 Am = Amoco Production Company CE = Cameron Engineers, Inc.

CO m o 1.2.6 UPPER AND LOWER AQUIFER PUMPING TESTS During the period starting December, 197^ and ending June, 1975, four lower aquifer and four upper aquifer pumping tests were conducted. The purpose of these pumping tests were to deter- mine aquifer characteristics and water quality on a areal basis. Some of the aquifer characteristics, including transmi ss i vi ty and artesian coefficients of storage, were discussed in the RBOSP Progress Report No. 3 in Section 1.2.6. The Interpretive Text Appendix contains simplified Jacob's plots and hydro- graphs. The data which backs up these plots are shown in Volume 2 and 3 in the Raw Data Section. More detai led analyses of the pumping tests are included in Section 1.2.8.6 of this report.

The early data consisted of measuring static water levels. In March 1975 the sampling program began. As per the RBOSP approved exploration plan, the deep aquifer mon- itor holes were sampled, static water levels and water quality data were collected monthly for 6 months. The ongoing sampling program will consist of monitoring static water levels, and water temperature on a monthly basis. Water samples will be collected once every six months and sent to the lab for analysis. The computer tabulation presented in the Raw Data volume of this report contains the lab analysis received to date for the monitoring program only. These analyses are listed under Method 3 and Method 3A. The reason for the differentiation between the two methods is as follows: 1. Prior to the July sampling, all of the samples were collected 20 feet below the static water level. 2. The July and later samples were collected at the depth of the aquifer in the monitor holes. 3. A study of the earlier analyses indicated that some of the constituents had significantly changed when comparing them with the analyses from the drilling or pumping test program. k. From a discussion with the Area Oil Shale Supervisors Hydrol- ogist, it was learned that on occasion where the hydrostatic head is great enough that chemical and geophysical reactions due to air, pipe and other contaminants in the hole can sig- nificantly alter the water quality. 5. Therefore, any samples which were found to vary significantly from the norm for that particular aquifer and hole were classified as Method 3A. ■69- RBOSP PROG J CO m o no Figure 1.2-40 is a map of Tract C-a and the surrounding area showing the location of the various monitoring and pumping holes.

The final point number corresponds to the point number used for the main headings elsewhere in this report, i.e., 1.2.8.1 discusses the surface water monitoring stations. 1.2.8.1 Surface Water Monitorina Stations As of the end of September, 1975, surface water data is being collected at 11 stations in connection with the hydrology pro- gram. Four of these stations are directly connected to the drainages "flowing" on to and off of Tract C-a. Two stations are located off Tract on drainages only remotely connected with Tract C-a. A total of five stations are monitoring possible waste disposal sites. The 11 stations have been constructed in stages. The Box Elder Gulch, Corral Gulch and the Dry Fork Stations near the west line of Tract C-a, the Corral Gulch Station east of Tract C-a, the Stake Springs Draw Station and the Yellow Creek Station near the White River were constructed during the early part of the summer 1974. The Rinky Dink Station was constructed in the fall of 1974. In the early fall 1975, the 4 stations associated with the 84 Mesa were constructed. 1.2.8.2 Surface Water Data Collection The surface water data collection program, which began in March, 1974, is reported in Section 1.2.2 of the RBOSP Progress Reports No. 2, No. 3 and No. 4. In these reports, tables of the raw data are presented. In addition, some of the chemical constit- uents are discussed in detail.

This summary shows the minimum, maximum and average values with the number of samples averaged. A reconnai sance study of the Piceance Creek Basin has indicated that there are only four perennial streams and tributaries with- in the basin. They are Piceance Creek, Dry Fork of Piceance Creek, Balck Sulphur Creek, and Yellow Creek, which is perennial only along the last few miles before it reaches the White River. The majority of the surface drainages in the Piceance Creek Basin would be classified as intermittent, that being they flow only during spring snowmelt and from precipitation of rapid thunder showers, or else flow continuously in given reaches such as Corral Gulch. 1.2.8.3 Alluvial Aquifers The alluvial aquifers which are found along most valley bottoms have a measured thickness which ranges from 0 to 1^0 feet. It is reported that the width of the alluvium is generally less than 1/2 mile. As would be anticipated, the alluvial aquifers are saturated where there are perennial streams, however, where the streams and surface drainages only have intermittent flows, the extent of saturation within the alluvial aquifers tends to be highly variable, and subject to seasonal changes. As discussed in Section 1.2.3 of this report, the water table in the alluvium was higher during the snowmelt runoff period than at other times of the year along the major surface drainage, how- ever, along the smaller drainages where the aquifer had been dry, it remained dry during the late spring snowmelt. > -77" RBOSP PROGRESS REPORT 1-2.8.4 Deep Aquifer Drilling Program RBOSP Progress Report No. 2 discussed in detail the drilling pro- gram conducted by RBOSP. In addition, data was also included from the Cameron Engineers and Amoco Drilling Programs. From this data, it was concluded that there are two aquifer systems present in the Parachute Creek Member of the Green River Forma- tion on Tract C-a. Although somewhat variable, the upper aquifer system is generally in the vicinity of the Mahogany Zone. The lower aquifer system is also variable but generally includes the R-3 zone, however, it has been observed as low as the blue marker and as high as the R-k zone. Discussed in some detail in our RBOSP Progress Report No. 2 under the Drilling Program are the following: Water Production Water Qual i ty Informal Pump Tests Geophysical Logs Summarizing Table 1.2.8.5 Deep Aquifer Completion Program With completion of G-S M~5 on July 16, 1975, there are a total of 35 holes on and around Tract C-a which have been completed as either dual completion monitor holes, upper aquifer pump test holes, lower aquifer pump test holes, upper aquifer monitor holes, lower aquifer monitor holes, or plugged and abandoned holes. With the exception of G-S M5 which is reported in Progress Report No. k, the remaining hole completions are discussed in detail in RBOSP Progress Report No. 2. It should be noted that until Ocotber, 1974, holes which were drilled prior to the lease had been left open at the request of the USGS. The leaving of the holes opened allowed the waters of the two aquifers to intermingle. Generally speaking, the upper aquifer system has a higher hydrostatic head than the lower aquifer system. Therefore, the flow was generally from the upper aquifer system to the lower aquifer system. ■78- [ RBOSP ~PRCX I > The first holes drilled on what is now Tract C-a were begun in the fall of 1971- Prior to the drilling by RBOSP, a total of 13 holes had been drilled and and/or cored through the two aquifers. Of these 13 holes, 3 had been open to the two aquifers for a period of 3 years, k had been open for a period of 2 years, and 6 had been open for a period of one year. It is estimated that approximately 15,000 acre-feet of water flowed from the upper aquifer system to the lower aquifer system prior to October 197**. This compares with 1 45 acre-feet produced from the lower aquifer during the RBOSP pumping test program and 30 acre-feet from the upper aquifer pumping tests. At the present time, all of the holes on and around Tract C-a have been completed in such a manner as to eliminate the communi- cation between the two aquifer systems. 1 .2.8.6 Upper and Lower Aquifer Pumping Tests A total of 8 pumping tests were conducted between December 197** and mid-June, 1975- Four of these tests were conducted in the upper aquifer system and k in the lower aquifer system. RBOSP Progress Report No. 3, Section 1.2.6 contains the Raw Data observations, simplified Jacob's plots, the transmi ss i vi ty and coefficients of storage values and calculations, and the water quality data from the pumping test program. The following discussion is a more detailed and in depth evalua- tion of the pumping test program. The purpose of this evaluation is to determine possible aquifer recharge, aquifer boundry con- ditions, and investigate any anamolous conditions that were ob- served. In addition, an investigation was conducted to determine the nature of the flow within tho aquifer. Although this investi- gation was inconclusive, it appears that the flow within the aquifer during pumping is radial with linear tendencies. -79- RBOSP PROGR ' During an investigation of the simplified Jacob's plots for the lower aquifer pumping, a break in slope at approximately 10,000 minutes was found to occur quite frequently. Using the Theis formula, it was calculated that this break in slope occurred when the radius of influence was on the order of 5 to 6 miles from the pumped hole. It is our opinion that this break in slope represents the intersection of the radius of influence with the Cathedral Bluffs boundary area. The following is a discussion of the water level changes at various times during each of the 8 pumping tests. From this discussion and the corresponding figures, it was observed that there generally is an elongation of the cone of depression along the NW-SE axis. However, in the upper aquifer system, the radius of influence was generally very limited. In fact, with the exception of the pumping of G-S 12, only one distant obser- vation hole had any measured water level change. Therefore, a limited amount of data was collected on the upper aquifer system. Almost without exception during the pumping of any given lower aquifer hole, every observation hole had a measurable drawdown. Therefore, a great deal of data was collected on the lower aquifer system. From this data the transmi ss i vi ty and the artesian co- efficients of storage were calculated over the majority of Tract C-a. Figures 1.2-41 to ] .2-kk are water level change maps during the upper aquifer pumping tests of CE 705A, G-S h~5, G-S 12 and T0-3 respectively. Cones of depression, favored direction of flow and boundary conditions are shown in these plots. -80- RSOSP frog: Figure 1.2-41 is drawdown at approximately 3,000 minutes during the second upper aquifer pumping test at CE 705~A (turned on 3/19/75, turned off 3/22/75). Drawdown, as it occurred in two observation wells TO- T and CE-709, is only in a northwest direc- tion from the hole. The boundary conditions that exist may be due to the northwest trending faults or fractures. Drawdown from pumping G-S 4-5 at approximately 23,000 minutes, as seen in Figure 1.2-42 only occurred in G-S 4-5 . The factors that may have contributed to this are (l) the low pumping rate, and (2) natural boundary conditions that may have limited the extent of drawdown in the areas immediately around G-S 4-5. The test began on May 2, 1975 and ended on May 19, 1975- Drawdown at approximately 13,000 minutes for the G-S 12 pumping test, as seen in Figure 1.2-43, was observed in three observation holes, AM 2-A, AM-3 and G-S 11. Drawdown was limited to an area southwest of the production well. The favored direction of flow is southwest of the Droduction well in the direction of G-S 11. Drawdown is only seen southeast of the production well, T0-3, on the Tract. Since no observation wells exist in off-tract directions from the hole, it is impossible to determine whether drawdown occurred in those directions. In the T0-3 pumping test, leaky conditions may have limited cone development. In viewing all of the upper aquifer pumping test drawdown cones together, it can be seen that the cone of depression from the various pumping tests do not overlap. This seems to reflect the structural geology of the area, as faulting appears to delineate barriers in the upper aquifer. Water level change during pumping tests (Figures 1.2-45 to K2-56) were prepared at different pumping intervals for the lower aquifer. The aysmmetrical shapes of the cones of depression indicate some -81- ~\ R30SP PROGR anisotropic conditions in the lower aquifer. The development of the cone of depression for each pumping test are discussed below. Lower aquifer pumping test at G-S D16 began on Feburary 15, 1975 and finished on March 9- 1975. Figures 1 .2-45 to 1.2-48 show the drawdowns at different time intervals. At approxi- mately one day (1350 minutes) after the pump was on, G-S 12 which is located next to the pumping site, responded with a drawdown almost 5 feet, whereas G-S 13 indicated a drop of 2-1/2 feet in its static water level. A few observation holes close to the production well were affected by the test. Their drawdowns ranged from 0.2 feet to 1.6 feet, depending on the locations. As the cone of depression continued to expand towards its maxi- mum, during the pumping test, the cone tends to develop a more gentle slope towards the northwest section of the tract where higher transmi ss i vi ty exists. At approximately 31,500 minutes after the pumping test started, all observation wells as far away as G-S Ml showed drawdowns from 3 feet to 9 feet. Lower aquifer pumping test at G-S D 1 7 began on January 18 and was completed by February 3, 1975- Figures 1.2-49 to 1.2-52 shows drawdown plots at various times after the first 2700 minutes of pumping. Observation hole TO-2 which is next to the pump site showed a drawdown of 34? feet. All observation wells on the tract were generally affected by the tests with drawdowns ranging from 6h feet at G-S 2-3 to approximately 0.5 feet at AM-2A and AM-3- The pump site is located at the northwest section of the tract and it is within the relatively higher permeability zone. The cone of depression expanded fairly evenly over the entire Tract. At the time before the pumping test was completed, drawdowns observed from all observation holes ranged from 46i feet at T0-2 to 6 feet at AM-2A. ■82- I RBOSP PROGRESS REPORT 1 Pumping tests were conducted at G-S D19 during the periods of April and May. Water level changes representing the ex- panding cone of depression during the test period of April 8 through May 5, 1975 are shown on Figures 1.2-53 to 1.2-56. The initial cone of depression after about 1 day pumping shows a somewhat bowl-like depression centered at the G-S D 1 9 site. There are two main anomalies affecting this symmetric cone of depression. One is the relatively rapid lowering of water level in G-S 8 and the other is a somewhat steepening of the cone of depression in the vicinity of G-S Dl8. The development of the cone after 8, 15 and 21 days show that these two features continue to develop and effect the cone of depression by creating a lower than expected zone that extends from G-S D 1 9 toward G-S 8, and a relatively steep gradient is developed in the northeast section of the tract. Also apparent from these figures is the general development of a more normal Theis type logarithmic de- creasing depression with distance from the pumping hole after 1 400 minutes. Leaky conditions between the upper and lower aquifers can be seen to exist from the pumping tests of the lower aquifer of G-S D 1 8 and G-S D 1 9 - Figure 1.2-57 shows water level changes of the upper and lower aquifers in T0-3, CE-702, G-S 4-5 and G-S 6 during the pumping tests of G-S D 1 8 and G-S D 1 9 . Figure 1.2-57 shows the correlat ion of upper and lower aquifer reaction during the pumping of the lower aquifer. The pumping of G-S D 1 9 and then the simul- taneous pumping of G-S Dl8 and G-S D 1 9 caused drawdown to occur in the lower aquifer and correspondingly in the upper aquifer. The leakage condition that is postulated is due to lower aquifer water migrating upward under a greater head pressure than exists in the upper aquifer, possibly through fractures, in the vicinity of T0~3 and CE-702. Pumping of the lower aquifer results in lowering of •83- f RBospTr73¥!~: the head pressure of the lower aquifer. This caused the system to begin to reverse itself and a water level drop in the upper aquifer since the head pressure of the upper aquifer begins to equal or becomes greater than the head pressure of the lower aqui fer . Water Quality comparison over the tract indicates a leakage con- dition in the vicinity of TO-3 and CE-702. The Water Quality data can be found in RBOSP Progress Report No. 4, Raw Data, Volume 1. The water of the upper aquifer in the vicinity of CE-702, TO-3 and GS-6 is much lower in quality than the general quality of the upper aquifer. One reason for hiqher constituent values in this area can be due to poorer quality lower aquifer water migrating upward and mixing with the upper aquifer. An investigation was made to determine to what extent the Jacobs logarithmic drawdown plots from upper aquifer pumping tests might indicate upper aquifer leakage. Drawdown plots which were pub- lished in RBOSP Progress Report No. 3 were examined. The nature of the Jacobs method assumes compliance with the Theis formula with the further stipulation that the distance between the mea- suring point and the pumped well is sufficiently small and the pumping time is sufficiently large. If these conditions are met, a logarithmic drawdown plot representing leakage conditions will exhibit a flattening trend with prolonged pumping time. In re- viewing the Jacob's Plots found in RBOSP Progress Report No. 3, Appendix, it is seen that after a period of time pumping, the drawdown curves begin to flatten out, rather than continuing a normal drawdown pattern. The apparent cause is that as the head pressures of the -8*»- I RBOSP PROGRESS REPORT upper aquifer is reduced, the greater head pressure of the lower aquifer begins to increase the rate of leakage thereby increases until the rate of leakage and recharge equals the rate of pumping, creating a static condition. The upper aquifer at CE-705A was pumped three separate times from February through March. Response from the first two tests was limited to the vicinity of CE-705A, with the exception of CE-709- Both drawdown curves from CE-705A and TO-1 show strong flattening with time. The third test which pumped at a relatively high rate and relatively long period pro- duced apparently a preferred direction response in CE-709 that also hinted at a leaky condition during the later phases of its response to the pumping of CE-705A. On this test TO-1 drawdown plots also indicated a leaky situation. Pumping TO-3 produced a drawdown curve that completely flattened and then increases. The increase in water level with time with a constant pumping rate has not yet been interpreted. -85- RBOSP PROGRESS F UPPER AQUIFER PUMPING TEST CE-705A No. 2 DRAWDOWN AT APPROX. 3000 MIN. iG-S Ml R99W CE-701 G-S DI7 A TO 2 G-S 2-3 G-S 4-5 |G-S 1 0CE-7O7 #CE-708 • ©G-S 7 6_S • G-S 8 AM 3# G-S DI6 { ■ G-S II # ,AM2A LEGEND ■■ TRACT OUTLINE > DRILL HOLES CONTOUR INTERVAL 5 FT TO 3^ CE-7029 G-S DI8 6-S6* G-S 10 G-S 15 I rbosp p.n^cr-Ess report!

It should be noted that the first reliable individual aquifer levels were collected in January 1975. The reason that reliable data could not be collected prior to this date was due to the fact that many holes in and around the Tract were not completed to isolate the two aquifers. Figures 1.2-63 and 1 .2-6*t show the upper aquifer piezometric levels on January 15 and July 15, 1975 respectively. A compar- ison of these two piezometric level maps indicates only very minor changes in the water levels for the upper aquifer during this 7 month period. It should also be noted that the slope of approximately 150 feet per mile and the shape of the con- tours have not changed. The only differences between these two dates is that the elevations have been displaced a short distance to the northeast. An evaluation of the hydrographs for the deep aquifer monitoring holes included in the Interpretive Text Appendix of the report indicates that from January to August 1975 water level changes in the upper aquifer system have ranged up to 30 feet of increase. Figure 1.2-65 shows the upper aquifer piezometric level changes during this period. As will be noted in the northeast corner of the Tract no change is indicated. In fact, in CE-702 a slight decrease in water level is observed. The remainder of the Tract water levels rose in the upper aquifer during the previously mentioned period. The greatest increases were in the northwest and south central parts of the Tract. These maximum increases were observed in approximately 3 core holes. Therefore it is felt that this is not an anomaly. 109- ^___ [ RBOSP PROGRESS REP The lower aquifer piezometric maps (Figures 1.2-66 to 1.2-70) between January 1975 and August 1975 show approximately a 25 foot drop in water levels across the Tract. The gradient on the piezometric surface is steepest in the northwest corner of the Tract. Over most of the Tract, the piezometric surface is very flat having less than 10 feet of relief. The piezo- metric surface steepens greatly to the northeast of the Tract. There were 15 holes total drilled by Amoco, Tosco and Cameron Engineering during 1971 and 1973- These holes were open between the aquifers until they were completed as monitor holes in the fall of 197^- Because of the difference in head between the upper and lower aquifer, a considerable amount of water flowed downhole into the lower aquifer resulting in a considerable rising of the piezometric surface in the area of the Tract. This mound is de- clining due to natural processes as the aquifer now returns to equilibrium. Between July and August, water levels have declined one to two feet over most of the Tract. The pumping of the lower aquifer also acted to lower the mound. Water level recovery was limited during the pumping tests because of the mound. Figure 1.2-71 shows the lower aquifer piezometric level change during the period from January to August 1975- The contours, excluding G-S Ml off-Tract, indicate a change from 20 to 30 feet of decreased head in the lower aquifer. As previously mentioned, this decrease in the water levels is due to the elimination of flow from the upper to the lower aquifer system. The area which shows the lowest change is in the vicinity of CE-707. Generally speaking, the area in the center of the Tract which has 28 feet of change or less has relatively lower permeability than other areas around the Tract as indicated in Figure 1.2-62. In fact, the area between CE-707 and G-S 8 has the lowest permeability. 110- RBOSP PR JRT~j An investigation was made to determine if recharge effects from seepage along fault structures or percolation was affecting the monitor holes water level over Tract C-a. Little information is known about the period and amplitude of short term recharge effects on the aquifer system, though a relatively long term steady state recharge and discharge situation has been postulated. Since the present water levels in the holes are being affected by previous pump testings and due to past interconnection of the two aquifers, it is expected that recharge effects would be evidenced by an alteration of the present water level trend by a superposi- tion trend. It was necessary to determine the initial baseline trend and extend this trend in time and then correlate later water level trends with estimated trends. An examination of the hydrographs to date revealed that water levels in the upper aquifer were rising and lower aquifer levels, after initally increasing, are now decreasing, No general sudden increases or decreases were found. An analysis of water level velocities versus time and acceleration versus time was undertaken from May and June hydrograph dates to establish a baseline trend. This trend was projected over July and August and then compared with actual water level trends over this period. Results for the upper aquifer indicated: water levels were going up at a slightly decelerating rate in May and June while in August the decelerating rate was four times as great; apparently random irregular drops and surges of about .8 feet occur over a period of two to four days. These occurrences have rapidly decreased from May through June. Results from the lower aquifer to date have indicated: water levels, though initially going up at a rapidly decelerating rate (58 times greater than the upper aquifer), are going down in August at an acceleration rate h times less than the deceleration rate in June. -111- RBOSP PROGRESS REPORTj Conclusions on recharge based on this study to date indicate that effects having periods greater than one month and amplitudes greater than .5 feet were not detected from June through August. The overall result of this work to date is the establishment of a preliminary baseline trend against which future hydrograph trends can be compared. Water level increases were noted in separate holesthat appeared to follow a time sequence. The holes that were affected are in sequence, CE-701, CE-707, CE-709 and G-S 9. An investigation of these increases involved establishing the time sequences, geomet- rical relationships, and correlation of the character of water level increases in each hole, and an attempt at correlation with other hydrological parameters. The apparent horizontal velocity of the event is kO feet/day. The magnitude of the effect was 5 to 13, *♦, 6 and 5 feet in time sequence. Periods of response in the holes were about 15, 5, 15 days for CE-701 , CE-707, and CE-708. Information was not available for the determination of period for G-S 9. The character of water level increases and de- creases between holes were similar with relative acceleration factors ranging from 2.5 to 5.1 and deceleration factors from 1.3 to 3. Areal correlation between other physical parameters such as aquifer thickness and tranmissi vi t ies were not successful. The result and conclusion of this study show the likelihood of an event moving in a through-like south-southeast direction affecting water levels in CE-701 , CE-707, CE-708 and G-S 9- The regularity of movement in time of this event to date suggests that other holes should be affected. Further correlation will be necessary to delineate the validity and/or nature of this interesting effect, Figures 1.2-72 through 1.2-108 are contours of selected chemical constituents on an areal basis for the upper and lower aquifers. 2- I RBi RBOSP PROGR o ii ■-'COOCO^COrvODTj^coO^crvtftK^fOOCOCDCOO'VOOr^N -r-or^OOOOOOO lp en u~> in ry cm — < MinNOC*^n\oino>o*rc(^coo^ o a* O O C CM CT* < ,ooc30>DOfyo^^Dinr^voo^ocr>ooooooo f— i r— i o 00 CM r-~ ^(O *p O —• — *r CO O O cc cocooooooooooooooooooooccoooooooo o OOOOr-^OOOr^OOOOOO—'OOO— 'OOOOOOOOOCOCMO o •~iOu->OOOOOu->-*O~-OLnOOOCMOOOOOOOOOCC0OOmo I Lf> OroOQOCOQOOOOOlOOvOOLncOkOO^-O-lCM-^CMr^OCOOOCO i «-i C CO O O vo » ^* j OO — < O LT) CM C r-~ cc c cm m ooooooooooooooooooooooooooocooooo OCOO— 'OOOinOOOininO— 'OOOOOOOOOOOOOOOOO —■«i-lOO~-.-iOO-HCM — lOOr^O^— 'O—'O-OOOLDU^OOCCOOCMC OOOOOOOCOOOOOOOOOO'HOlOin**'— 'OO-^GOOOO—' I I I UT> I I II III I I I I I VO I I I C*"!

Eight alluvial water monitoring test holes were drilled to obtain subsurface hydrology and environmental baseline data around 84 Mesa in connection with oil shale Tract C-a, Rio Blanco County, Colorado. Becker Drills, Inc., was engaged to drill the holes by Mr. Russell Darr of Wright Water Engineers, Inc. Drilling began on June 18, 1975, and was completed on June 25, 1975. Surface construction and preliminary measurements were completed in the following days. A daily report is in- cluded as Appendix A. HOLE LOCATIONS An index map showing the 8 alluvial monitoring wells is Figure 1. The locations of the 8 holes are listed in the order of drilling as follows: S-24 NW1/4 NET/4 SE1/4 Sec. 30, T.1S, R98W S-22 NET/4 SE1/4 NE1/4 Sec. 16, T.1S, R98W S-23 NW1/4 SE1/4 NE1/4 Sec. 8, T.1S, R98W S-19 SW1/4 SW1/4 NE1/4 Sec. 12, T.

Locations S-15 and S-24 were drilled as originally staked. Sites S-16, S-17, S-22 and S-23 were drilled as located by Mr. Darr personally in the field -1- RBOSP FRCGn::3G RE in uwmm^B Jin ri rrcpriri iimty — jil.j n — nr>LWi^fts^i.rary^ CO ^v ^3i . ^ • v V ?^. <^ ■> iV^^v^v s a, I. - „ . . . , ....... \ „ .V : -~~\ . . / \V\ -2- RBOSP PROGRESS REPORT D I Well S-18 was located using both verbal instructions from Mr. Darr and from waps of the area because the original stake could not be found. The wells are located on Yellow and Duck Creeks and their tributaries in and around the 84 Mesa. Drilling Method The Becker Hammer Method was employed using Becker 5-1/2" OD by 3-1/4 ID double-wall drive pipe and reverse air circulation. This method uses a diesel hammer to drive the drill-pipe into the ground, air is forced down the annulus of the double-walled drive pipe. The air lifts the cuttings up through the center of the drive pipe and discharges into a cyclone assembly. Samples can be obtained continuously from the base of the cyclone. Personnel of the Becker drilling crew were: Kenneth Long, Driller Kermit L. Krueger The advantage of using the Becker Hammer Method in any application is the recovery of clean, continuous geological samples free of up hole cuttings contamination that is common to conventional drilling methods. The disadvantages of the Becker drill were described in the previous alluvial program report. Well Construction The drilling log of each of the 8 alluvial holes is included in the appendices in numerical order according to well number. Two-inch inside diameter (ID) plastic casing was installed in each hole. Once the casing was installed, the annulus was backfilled with washed gravel. ■3- RBOSP PROGRESS REPC To protect the well, 5 feet of 7-inch outside diameter (OD) steel casing was cemented at the surface. Caps were made by welding a plate on 7-inch OD thread protectors. The sides of the protectors were split in two places to allow for a friction fit. The general construction used for each test well is shown in Figure 2. Alluvium The alluvium in the Yellow and Duck creek drainages in the vicinity of the 84 Mesa consists of mostly very fine material derived from the Uinta Formation and Parachute Creek Member of the Green River Formation. The most well developed alluvium is in the mainstems of Yellow and Duck Creeks. The material in their tributaries consist mostly of slope wash and fan material. Test Wells The physical parameters of the test wells are summarized in Table 1. The table shows some difference between the measured depth and drilled depth. There differences have two causes. One is that some of the fine material stayed in the drill pipe until the casing was installed, the second reason is that in some cases a saturated clay was encountered which can move fluidly through the perforations. Aquifer Testing No aquifer tests were conducted during drilling. S-19, S-22, S-23, and S-24 were the only holes to show indications of water. Of these holes, % S-23 produced a measured 60 gpm at 78 feet and was still developing, and S-24 produced an estimated 15 to 20 gpm from about 64 feet. The other holes pro- duced little water during drilling. -4- RB03P PROGI 0 FIGURE 2 GENERAL CONSTRUCTION OF TEST V/ELLS NOT TO SCALE MEASURING POINT (M.P) TOP OF 7" O.D.

Air is forced down the annul us of the double-walled drive pipe and out the bit, where the air lifts the cuttings and water up the center of the drive pipe. Consequently, when using the Becker drill for pumping, only a wery small area of the aquifer at the bit is actually tested. Also, only an informal type of recovery test can be conducted because there is no room to measure water levels on the outside of the drive pipe. An estimate of the Transmissivity of the alluvium could be obtained by conducting slug injection or other types of tests on the water bearing holes. For the slug injection test five to ten gallons of water could be bailed out of a hole, then after the water level stablized the water could be reinjected as a slug and the resultant recovery measured with time. Before testing each well should be cleaned out and developed using a water jet. The water jet consists simply of a source of water, a pump and a garden hose or small diameter pipe that will fit down the well. Water Quality The holes containing water were first sampled on June 30, 1975. The samples were turned over to Wright Water Engineers to become an addition to the on-going water sampling and ground water monitoring program for the Rio Blanco Oil Shale Project. The field parameters measured at the time of sampling are listed below in Table 2. Conclusions and Recommendations Eight alluvial test wells were drilled and completed as instructed by Mr. Russ Darr, Wright Water Engineers, Inc., consultant to the Rio Blanco Oil Shale Project. -7- RBOSP PROGRESS REPC — ^jp. All of the alluvial wells should be cleaned out using water circulation. If an estimate of transmissivities is desired, the slug injection method or the constant head-variable discharge injection method can probably be used.

The re- sults are shown in Table 1. There were some problems at this point. The flume was too large for the flows being measured, and a smaller one was not immediately available even through the USGS office in Meeker. Another problem was that the flume had to be installed far enough away from the rig to catch the com- bined runoff from both the wellhead and the blooey line. The weathered ground surface is quite permeable and a significant, but unknown quantity of the water was lost before it could reach the flume. Water Quality The quality of the water produced from M-5 during drilling is given in Table 2. A water sample exists for the first water . encountered, but this water was sampled again on July 16, 1975. The latter sample is not as muddy as the first and for this reason, will provide a better picture of the water quality of the first water. Well Completion The general construction of the M-5 monitoring well is given in Figure 3. Only the first water is being monitored. The completion technique used for M-5 allows for monitoring the "upper" aquifer at a later date. This procedure is documented as follows: First, the zone open to the perforations must be squeezed out with cement under pressure. Enough water must be pumped in behind the cement to clear the 2 3/8-inch tubing. Then the cement must be allowed to set. Next, the 2 3/8 tubing must be cleared of any residual cement and the sand overlying the upper tubing disk. This can be done with 1-inch or smaller pipe and water circulation. -5- A M E R O N ENGINE ["rIoSP PROGRESS RE E R S I | TABLE 1 WATER PRODUCTION DRILLING DRILLING OF M-5 Formula for parshall flume of 6-inch throat width is Q=2.06 Ha158 Q=flow rate in cubic feet per second, and Ha=the height of the water in feet flowing through the flume.

Finally, circulating to bottom to clean out any cavings, and the "upper11 aquifer is ready to be monitored. Bailing Test On July 16, 1975, a bailing test was conducted to make sure that the water bearing zone was open to the well. First, the static water level was measured. Then, 5 gallons of water were bailed out of the hole with a stainless steel sampler that holds slightly more than 1/2 gallon. Afterwards, the static water level was measured again to see if it had recovered, and it had. Five gallons of water is enough to lower the water level inside 2 3/8-inch tubing by 30 feet. Considering the annulus outside the tubing the lowering of the water level would be less. The results of the bailing test are given in Table 3. After the conclusion of the bailing test, a water sample was taken and entered into the sampling and monitoring program being conducted by Wright Water Engineers, Inc. for the Rio Blanco Oil Shale Project. -8- AMERON ENGINEER RBOSP PR Figure 3.
