k4 KLEINFELDER and at varying intervals. The eight groundwater samples will be collected using a disposable or stainless steel bailer or by positive displacement through polypropylene tubing attached to a stainless steel ball valve. A disposable screened PVC casing will be placed within the pushprobe holes to filter out sediment. The PVC casing will include a 5 to 10 foot .010-0.020-inch slot screened interval, placed within the water bearing zone, prior to groundwater collection. The groundwater will be decanted into laboratory supplied bottles directly from the tubing or using pre-cleaned stainless steel bailers. Upon completion of the soil and groundwater sampling the soil borings will be grouted the same day in accordance with SJC/EHD requirements. TASK 3.0 LABORATORY ANALYSIS After collection, the soil and groundwater samples will be labeled, logged on a chain-of-custody form, and immediately stored in an iced cooler. The samples will be transported under chain-of- custody control to Kleinfelder's office and then transported by courier in a sealed container to a State Certified Laboratory to perform the requested analyses. Approximately 24 soil samples (estimate three from each of eight soil borings) and eight groundwater samples will be submitted for the following analyses. • Nitrate as N by EPA Method 300.0 • Total Kjeldahl Nitrogen (TKN) by EPA Methods • Ammonia as N by EPA Method 350.3 • Fecal Coliform by EPA Methods The samples will be analyzed on a standard 10-day working turn-around time (TAT). Expedited TATs can be provided at additional costs. TASK 4.0 REPORTING Upon completion of soil and groundwater sampling, and receipt and review of analytical results, the following items will be included in our Phase II ESA report for client and agency review: • A description of field activities, observations, and protocols; • Lithologic logs; • Results of the soil sample analysis with copies of certified analytical laboratory results with chain-of-custody documentation; • A graphical representation of soil sampling locations; • Description and documentation of QA/QC procedures employed for field and laboratory work; and • An assessment of the results, with conclusions and recommendations. 02001 PROP.ENV/ST04P222/DGD:ss Page 6 of 10 Copyright 2004,Kleinfelder,Inc.
