KLE1NFELDER <br /> EXPECT MORE <br /> Purge water will be placed into 5-gallon buckets and then poured onto the ground some <br /> distance from the well, but far enough away to not drain near the well box/opening. <br /> After collection, the groundwater samples will be labeled, logged on a chain-of-custody <br /> (COC) form and immediately stored in an iced cooler. The samples will be transported <br /> under COC control in a chilled ice chest directly to Kleinfelders office to be stored in a <br /> refrigerator within a locked room. The samples will be relinquished to laboratory <br /> personnel in a chilled ice chest and delivered under COC control to a State-certified <br /> analytical laboratory for the requested chemical analyses. The samples will be <br /> analyzed on a standard 2-week turn-around-time (TAT). <br /> A.2 GROUNDWATER ANALYSES <br /> OLWD has been using a local laboratory, FGL Environmental (FGL) of Stockton, <br /> California. Groundwater samples collected from the nine monitoring wells will be <br /> submitted for the following bulleted analyses. The following listed analyses/analytes are <br /> followed by proposed reporting limits [or practical quatitation limits (PQLs) as <br /> referenced by FGL], sample bottle/s and applicable preservative/s: <br /> • Total Dissolved Solids (TDS) by EPA Method 160.1 [PQL = 40 mg/l, poly bottle - <br /> unpreserved] <br /> • Nitrate as Nitrogen by EPA Method 300.0 [PQL = 0.1 mg/I, poly bottle <br /> unpreserved] <br /> • Total Kjeldahl Nitrogen (TKN) by EPA Method 351.4 [PQL = 0.5 mg/I, poly bottle <br /> with H2SO4 preservative] <br /> • pH by EPA Method 150.1 [No PQL, poly bottle, unpreserved] <br /> • Trihalomethanes by EPA Method 8260B [0.5 µg/l, VOAs with HCL preservative] <br /> • Boron by ICP [0.1 mg/I, **metal — see bottle description below] <br /> • Chloride by EPA Method 300.0 [1 mg/l, poly - unpreserved] <br /> • Iron by ICP [0.05 mg/I, **metal — see bottle description below] <br /> • Manganese by ICP [0.01 mg/l, **metal — see bottle description below] <br /> • Sodium by ICP [1 mg/I, **metal — see bottle description below] <br /> • Total Coliform Organisms by EPA Method 9221 B [1.1 MPN, poly bottle — NA2S204 <br /> preservative] <br /> Annual frequency sampling for the monitoring wells will also include the following <br /> Standard Minerals: <br /> 48093.E01/ST07R052/CJC/Iv Page A-2 <br /> ©2007 Kleinfelder, Inc January 26, 2007 <br />
