New PVC screened and blank sections will be used at each probe location. Stainless steel bailers, ball valves, and other down-hole re-useable equipment will be decontaminated prior to use at each sampling location by stream cleaning or scrubbing in a non-phosphate detergent wash followed by a distilled water rinse. The groundwater samples collected will be decanted directly into laboratory supplied containers appropriate for the requested analyses. After collection, the four 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 chilled container to a State Certified Laboratory to perform the requested analyses. Kleinfelder is proposing the submittal of four groundwater samples during the push probe investigation for the following quarterly and annual frequency analyses currently established by the current Waste Discharge Requirements: Quarterly frequency analyses: • Nitrates as Nitrogen (N) by EPA Method 300.0, • Total Kjeldahl Nitrogen (TKN) by EPA Method 351.1, • Total Dissolved Solids by EPA Method 2540 C, • Total and Fecal Coliform Organisms by SM 9221 B, • pH by SM 4500-H, • Chloride by EPA Method 3010A, • Boron by EPA Method 3010A, • Iron by EPA Method 3010A, • Manganese by EPA Method 3010A, • Sodium by EPA Method 3010A, and • Trihalomethanes by EPA Method 8260. Annual frequency analyses: • Alkalinity (bicarbonate, carbonate and hydroxide) by EPA Method 2320B, • Calcium by EPA Method 3010, • Magnesium by EPA Method 3010, 48093.E01/ST010R109 Page 3 of 6 March 26, 2010 Copyright 2010 Kleinfelder
