'. k'q KLEINFELDER <br /> t4 LABORATORY ANALYSIS <br /> ' 4.1 SOIL ANALYSIS <br /> Two soil samples from each of the deep borings in the pond areas were collected for analysis. <br /> ' The soil samples analyzed were collected from clays (aquitard material) as they were <br /> encountered. The soil samples were tested for the following parameters: <br /> ' • Hydraulic conductivity utilizing a flexible wall permeameter-using ASTM 5084=90. <br /> • Grain size distribution using ASTM D-422. <br /> The soil samples collected for the hydraulic conductivity analysis were submitted to Sierra <br /> Testing Laboratories (Sierra) in El Dorado Hills, California and tested in the "undisturbed" <br /> condition and not remolded as specified by RWQCB in C & A Order #05-00-717. Soil samples <br /> collected for the grain size distribution analysis were submitted to Kleinfelder's materials testing <br /> laboratory in Stockton, California for the deeper soil samples, and Sierra for the shallow soil <br /> ' samples (due to limited sample quantity). <br /> ' Soil samples collected from the shallow soil borings in the spray fields were not submitted for <br /> laboratory analysis. <br /> ' 4.2 GROUNDWATER ANALYSIS <br /> ' Two groundwater samples (TW-1 and TW-2) collected from the deep soil borings were submitted <br /> to Sequoia Analytical in Sacramento, California, a State certified laboratory, and analyzed for the <br /> ' following: <br /> • Sodium by EPA Method 200.7 <br /> • Chloride by EPA Method 300.0 <br /> • Total Dissolved Solids by EPA Method 160.1 <br /> • Dissolved Inorganic Solids by EPA Method 160.4 <br /> ' • Specific Conductivity by EPA Method 120.1 <br /> The samples were analyzed on a normal laboratory schedule requiring approximately two weeks <br /> (ten working days) for completion. <br /> 20-2594-03.004/2011R447 Page of 16 <br /> ' Copyright 2001 Kleinfelder,Inc. lune 8,2001 <br />
