1 KLE/NFELDER <br /> V Mght ft ple.Ni9ht5IuWns. <br /> samples will be labeled, logged on a chain-of-custody form, and immediately stored in an iced <br /> cooler. The samples will be transported under chain-of-custody control to Kleinfelder's office <br /> and then transported by courier in a chilled container to a State Certified Laboratory to perform <br /> the requested analyses. <br /> Kleinfelder is proposing the submittal of seven groundwater samples during the push probe <br /> investigation for the following analyses (in accordance with the list of analyses) established by <br /> the current Waste Discharge Requirements: <br /> • Nitrates as Nitrogen (N) by EPA Method 300.0 <br /> • Total Kjeldahl Nitrogen (TKN) by EPA Method 351.1 <br /> • Total Dissolved Solids by EPA Method 2540 C <br /> • pH by SM 4500-H <br /> • Chloride by EPA Method 3010A <br /> • Boron by EPA Method 3010A <br /> • Iron by EPA Method 3010A <br /> • Manganese by EPA Method 3010A <br /> • Sodium by EPA Method 3010A <br /> • Trihalomethanes by EPA Method 8260 <br /> • Alkalinity (bicarbonate, carbonate and hydroxide) by EPA Method 23206 <br /> • Calcium by EPA Method 3010 <br /> • Magnesium by EPA Method 3010 <br /> • Potassium by EPA Method 3010 <br /> • Total Hardness by EPA Method 3010 <br /> • Total Sulfate by EPA Method 300 <br /> The samples will be submitted on a standard 10 to 15 business day turn around time. <br /> After completion of the initial sampling event, a bentonite seal will be placed above the sand <br /> interval to surface grade. The temporary casings will be fitted with a PVC slip cap and enclosed <br /> within irrigation boxes. Kleinfelder will evaluate and forward the initial data so the district can <br /> decide if more sampling may be desired. After determining that the wells are no longer needed <br /> by OLWD and that EHD requires destruction, the temporary wells will be pulled from the ground <br /> and the boreholes will be closed by backfilling the borings with a neat cement grout on a <br /> separate occasion. Probe cuttings and water will not be contained and will be spread around <br /> the boring sites. <br /> Task 3— Reporting <br /> Upon completion of the field activities and receipt of the analytical results, a report of findings will <br /> be prepared for client and agency review. The report will include: <br /> 124374.T1/ST013R0535 Copyright 2013 Kleinfelder <br />
