k'■ KLEINFELDER <br /> 5 LABORATORY ANALYSIS <br /> After collection, groundwater and soil samples will be labeled, logged on a chain-of-custody <br /> form and immediately stored in an iced cooler. The samples will be transported under chain-of. <br /> custody control in a chilled ice chest directly to a State-certified analytical laboratory for the <br /> requested chemical analyses. The samples will be analyzed on a standard 12 working day turn- <br /> around-time (TAT). A total of three groundwater samples and nine soil samples will be obtained <br /> for this baseline assessment. The following subsections list the proposed analyses for the <br /> groundwater and soil samples. <br /> 5.1. GROUNDWATER ANALYSES <br /> Three groundwater samples collected from three new monitoring wells will be submitted for the <br /> following analyses and methods: <br /> • Nitrates as Nitrogen by EPA Method 300.0 <br /> • Total Kjeldahl Nitrogen(TKN) by EPA Method 300.0 <br /> • Ammonia as N by EPA Method 350.3 <br /> • Total Dissolved Solids(TDS)by EPA Method 160.1 <br /> • Fixed Dissolved Solids by EPA Method 160.1 <br /> • Calcium by EPA Method 200.7 <br /> • Magnesium by EPA Method 200.7 <br /> • Sodium by EPA Method 200.7 <br /> • Sulfate by EPA Method 300.0 <br /> • Total Alkalinity(Series)by SM 403 <br /> • Hardness by EPA Method 130.2 <br /> • Total and Fecal Coliform Organisms by SM 9221B <br /> • Specific Conductivity by EPA Method 120.1 <br /> • pH by EPA Method 150.1 <br /> In the event that the above analytical methods are not used, a comparable method shall be <br /> employed. <br /> 50890.E01/STOSR358/JDZ:Iv <br /> C 2005,Kleinfelder, Inc.
