Lead in Drinking Water Sampling and Analysis Plan (SAP) 



1.0 Purpose of the SAP 

This SAP is for the exclusive use of SFUSD staff and consultants for collecting, 
documenting, submitting, and summarizing the lead in drinking water quality data within 
the SFUSD. The purpose of the SAP is to generate: 

Accurate, reproducible and defensible results that would provide a 
sound foundation for any followup actions. 

1.1 Disclaimer 

This SAP has been prepared jointly by representatives of Forensic Analytical Specialties, 
EORM and SCA Environmental, Inc. While the SAP specifies certain requirements for 
survey execution and the reporting of findings, it is the sole responsibility of each 
environmental consulting firm to fulfill their contract. This SAP should in no way be 
construed as limiting a surveyor's responsibility in this regard. By using any material, 
ideas or methods, delineated in this SAP, the user agrees to wholly indemnify Forensic, 
EORM and SCA for any and all lawsuits, penalties and expenses arising from such use. 

1.2 References 

The following references were consulted for assembling this SAP: 

A. 40CFR141.2 defines first draw sample as a 1-Liter sample of tap water, collected in 
accordance with 1414.86(b)(2) that has been standing in plumbing pipes at least 6 
hours and is collected without flushing the tap. 

B . 40CFR141.86 specifies that acidification of the first draw sample may be done up 
to 14 days after the sample is collected, rather than using pre-acidified bottles. 
Acidification must be conducted in the original container for >16 hours. 

C . AWWA Standard Methods for the Examination of Water and Wastewater, 1 9th ed., 
1995. 

D. Federal Register, June 7, 1991, p. 26460: Maximum Contaminant Level Goals and 
National Primary Drinking Water Regulations for Lead and Copper. 

2.0 Scope of Work for Consultants 

The scope of work for each consultant retained for this task will be as follows: 

A. For the sites assigned on the attached "Assignment Spreadsheet", collect one 
sample for each drinking fountain; and one sample each for other possible drinking 
water sources (such as kitchen taps, including the sources inside a faculty lounge, 
but not a janitor's slop sink) in the assigned site(s). Follow the procedures, data 
collection, QA/QC specified in this SAP. 

B . Complete all work within the following schedule: 

• Start - 8/6/97.

3.0 Sampling 

3.1 Equipment and Materials Required 

Equipment required shall include, but is not limited to, the following: 

• Clipboard with pencil or pen(s); 

• Non-sterilized, non-powdered disposable latex gloves, e.g., Action Scientific (800- 
678-1033) No. A-105; 

• New, non-sterilized plastic 1 -liter bottles with screw-on caps (to be provided by 
SFUSD); 

• Sharpie© marking and high-lighter pens; 

• Flashlights and batteries; 

• Saran wrap; 

• Keys; 

• Identifications; 

• Site maps / floor plans; 

• Field data form (chain of custody form); and 

• Satchel or shoulder bag for carrying supplies. 

3.1.1 Access / Security 

SFUSD will arrange for keys to be made available to the consultants so that escorts will not 
be required. Consultant will: notify the security department at (415) 695-5665 to dis-arm 
the site at a pre-specified time for the survey; and notify the site contacts regarding the site 
visits and schedule. 

Prior to mobilizing, each consultant will provide SFUSD with a roster of their field staff 
involved in this survey showing: 

• names 

• social security number 

• driver's license number

3.2 Drinking Water Lead Contamination Sampling 

Collect the water samples using the following procedure: 

A. For the sites that have not been dormant for the summer break, skip the rest of this 
step and go to step B. For the sites that have been dormant for several weeks due 
to the summer break, go to the site 24 to 36 hours before the scheduled sampling 
time and flush each accessible drinking water source for at least 10 minutes. 
During this flushing, ensure that the drain is working properly to prevent potential 
water damages. 

B. Collect the "first draw" water in the morning prior to the arrival of any staff (in 
lieu of the morning schedule, weekends will be a viable option provided that water 
should be unused for a minimum of 6 hours prior to sampling). The purpose is to 
allow for a "worst case scenario" in terms of leaching of lead into water from 
plumbing and fixtures. Speak to the site contact prior to the date of the survey, to 
find out when building occupants arrive, and if necessary, to select a day when it is 
feasible to have a 6-hour time with no water usage. 

C . Collect one sample from each accessible drinking water source, including drinking 
fountains and kitchen sinks. If drawing water from sinks, sample cold water. 

D. To sample, remove the cap from the 1 -liter plastic sampling bottle, and slowly fill 
the container. DO NOT USE ANY WATER IN THE BUILDING UNTIL 
AFTER SAMPLING IS COMPLETE, INCLUDING TOILET 
FLUSHING. 

E. Label the sample with an indelible marker on the side of the bottle (not the cap) as 
follows: 



site 


sample ID 


e.g., Garfield HS 


6 (6th for the site) 



F . Complete the Water Sample Form as each sample is collected. 

G. Identify the sample ID on the site plan or floor plan as each sample is collected. 

H . Submit the Water Sample Form as a chain of custody form. 

I . Submit the samples to the laboratory designated by SFUSD. 

3.2.1 Sampling Protocol for Return Trips 

For re-sampling as a followup to further evaluate the various parameters affecting the lead 
content in the water sources, collect samples using the following procedures: 

A. Collect the 1st draw sample (i.e., >6 hours of residence time) after flushing for 30 
seconds. 

B . Collect the 2nd sample after flushing for another 30 seconds. 

C. Collect the 3rd sample (no flushing) with a 4-6 hours lapse after the 2nd sample. 



printed: October 14, 1997 

Page 4 



San Francisco Unified School District (SFUSD) 
Lead in Drinking Water Sampling and Analysis Plan (SAP) 



D. Miscellany: 

a. Sample ID - keep the same sample ID as in the initial trip, but add A, B, C 
as suffixes corresponding to the 1st, 2nd and 3rd draw return trip samples. 

b . Record on the field data sheets two pieces of information: 

i . the # of seconds it takes to fill the 1 -liter bottle, and 

ii. the arch height of the water jet (inches), est. from the jet opening to 
the top of the arch. 



3.3 Items to Avoid 

Consultants must ensure that the field staff do not commit these errors: 

A. Labeling samples on the cap of the bottles. 

B. Labeling samples without following the convention listed in Section 3. 2D. The 
convention eliminates mix up of the est. 2,000 sample results. 

C. Putting the sampling bottle cap face down on the floor without using a fresh Saran 
wrap; or juggling the cap with the fingers accidentally touching the cap's interior. 

D. Not using disposable gloves while handling the opened bottles. 

E. Not completing the field data sheets and marking the locations as each sample is 
collected. 

F . Using sampling bottles not provided by SFUSD for this project. 

G. Sampling water sources that are non-operational (dribbling). Instead, record the 
unit as non-operational on the sample form, and mark the location on the floor 
plan. 

H. Sampling every faucet in a "gang drinking fountain" in which the faucets are 
identical. Only one sample is needed under that situation. If the faucets appear to 
have been modified and consequently not identical, collect one sample for each type 
of faucet. 

4.0 Analytical Method 

For standardization, all water samples will be analyzed ONLY by Graphite Furnace 
Atomic Absorption (GFAA) in accordance with EPA Method 239.2, with an anticipated 
detection limit (defined as the Method Reporting Limit) of <5 ppb. 

Note that the method numbering reference may be changed by EPA in the near future. 
Again, SFUSD allows only the use of GFAA for lead in water analysis. 

5.0 Quality Assurance & Quality Control 



printed: October 14, 1997 

Page 5 



San Francisco Unified School District (SFUSD) 
Lead in Drinking Water Sampling and Analysis Plan (SAP) 



Quality Assurance (QA) and Quality Control (QC) are essential elements of this SAP; their 
documentations are crucial to the validity of the results, conclusions and recommendations 
of the overall project. 

5.1 Field OA/OC 

A. Pre-qualitv controlled sampling bottles. SFUSD will provide the 1 -liter sampling 
bottles that have been quality controlled for background lead contents (as 
documented by the manufacturer. One (1) % from each lot of the bottles will have 
been analyzed by the same method referenced in Section 4.0 after filling in with 
deionized water and acidified. 100% of these quality controlled bottles will have to 
show lead contents at less than the detection limit of the method. 

B . Blanks. The field surveyors will collect a blank for each site and submit the 
blank as a sample for analysis. Collect the blank by randomly selecting one of the 
sampling bottles, go through the entire process, including opening the cap, placing 
the cap facing up on the Saran wrap, simulating the water collection process (but do 
not collect any), closing the cap, labeling the bottle, etc. (The Blanks will be filled 
with de-ionized water by the lab, see Section 5. 2.2 A). 

C . Spiked Field Samples (1 per 20 field samples). For every 20 samples being sent in 
by the consultant, submit one spiked sample to be provided by SFUSD. Disguise 
the spiked samples as field samples. Spiked samples will be in the range of 5 ppb 
to 100 ppb of lead. 

D. Saran wrap. Given that it would not take much cross-contamination to create a 
false positive result exceeding 15 ppb of lead, this SAP requires that fresh Saran 
wrap (> 1 SF) be used by the field surveyors for temporarily placing the sample 
bottle cap (facing up) while the bottle is being filled. Samplers must NOT try to 
juggle the cap in between their fingers while sampling. Dispose of the wrap after 
each sample. Do NOT re-use the wrap. 

E. Training. Each consultant firm must document the following training have been 
provided to each field sampler PRIOR to any site work: 

1 . Highlights of this plan. 

2. Trainer to demonstration sampling, labeling, completion of forms. 

3 . Field sampler to demonstrate sampling, labeling, completion of forms. 

4. If needed, repeat steps 2 and 3 until the trainer is satisfied that the field 
sampler can perform the tasks with 100% compliance to the requirements. 

F . Review of Completed Forms. The Project Manager of each consultant must review 
100% of the first batch of samples and completed forms from each field sampled. 
Thereafter, conduct such review at the rate of >5%. The Project Manager will 
decide re-training of the field sampler (see Section 5.1 D) accordingly. 

G. Re-survey. SFUSD may, on a selective basis, assign another consultant to re- 
survey a particular site for statistical validation. 



5.2 Laboratory OA/OC 



printed: October 14, 1997 

Page 6 



San Francisco Unified School District (SFUSD) 
Lead in Drinking Water Sampling and Analysis Plan (SAP 



Completed Chain of Custody forms will accompany field samples at all times including 
transit to the laboratory. Forms will be signed, dated, and time marked prior to being 
relinquished by each responsible party. 

5.2.1 Certifications 

Laboratories performing the analysis must be certified by the California Department of 
Health Services for water quality analysis. The California Department of Health Services 
requires certified laboratories to participate in EPA water performance testing. 

5.2.2 Blanks, etc. 

The laboratory will perform these quality assurance tasks: 

A. Field Blanks. Fill the blanks with 1 liter of deionized water (lead contents below 
the detection limits of the analytical method), acidify with nitric acid for >16 hours 
in the field containers prior to running the blank as a regular sample. The blanks' 
results should be treated as follows: 

1 . If the blank of a particular batch is < detection limit of the method, no 
action. Report the results of the batch's samples without adjusting for the 
blank's value. 

2 . If the blank of a particular batch exceeds the detection limit of the method, 
but no more than 200% of the detection limit, adjust the individual sample 
results by deducting the blank's value. 

3 . If the blank of a particular batch exceeds 200% of detection limit of the 
method, the laboratory will investigate the source(s) of the contamination, 
including the possibilities of invalidating the results of that batch's results. 
Notify the SFUSD Project Manager (Bruce Giannini) for possible follow up 
actions, including re-sampling. 

B. Lab Blanks (1 per 20 samples). The laboratory will document that all reagents, 
including the deionized water used for the field blank, laboratory glass ware, etc., 
will have lead contents below the detection limits of the method. Run one (1) lab 
blank per 20 samples; but no less than one per shift of analysis. 

C. Inter-laboratory Analysis. Each laboratory will archive 5% of the samples for 
transmittal to another designated laboratory for re-analysis. These samples should 
be selected randomly on a daily basis covering a range of lead contents. The labs 
will send these archival samples directly to Forensic for re-analysis. 
Results within 15% of the mean are considered acceptable. Results that deviate 
from this limit would trigger a notification to the Project Manager of SFUSD (Bruce 
Giannini) to determine the needed followup activities. 

D. Intra-laboratory Analyses. Each laboratory will document that: 

a. >10% of the samples are re-analyzed in-house daily and that the results are 
within 10% of the original result. 

b. 5% of the samples are spiked and re-analyzed with each spiked result within 
20% of the expected value. 



printed: October 14, 1997 

Page 7 



San Francisco Unified School District (SFUSD) 
Lead in Drinking Water Sampling and Analysis Plan (SAP) 



Each laboratory will investigate the causes of any results that deviate from these 
limits, and document the followup actions and justifications that the deviation has 
not caused the reported results to be invalidated. 

F . Other In-house Laboratory Requirement. The aforementioned Q A/QC tasks do not 
replace or obscure the individual laboratory's in-house QA/QC program, or the 
need of such program. 

6.0 Data Summarization 

The laboratories will transmit the laboratory reports directly to the SFUSD and the 
designated consultant for integrating and summarizing the data. To minimize the loss of 
data reports, individual consultants will not be sent the laboratory reports by the 
laboratories. Each Consultant will send copies of the field data sheets to the following 
designated consultant on a weekly basis: 

Chuck Siu

21 14 Berkeley Way 
Berkeley, CA 94704 
Tel: 510-848-0390 
Fax: 510-848-3328 

7.0 Billing and Payment for Laboratory Services 

SFUSD has contracted these laboratories for the analysis and post-analysis logistics, 
including direct payment for the lab analyses: 

A. Sequoia Laboratory 

689 Chesapeake Drive, Redwood City, CA 94603 

B . MicroAnalytical, Inc.

Field samplers must use the following SFUSD' s "Lead Water Sample Form" as the field 
data sheet / chain of custody. This form has been modified slightly for this SAP. The 
Assignment Spreasheet shows the current sites assigned to each consultant. Note that 
SFUSD reserves the right to re-assign the sites if a consultant's performance falls behind 
the schedule or is indicative of such a potential.
