In accordance with <br /> a conversation with CV Water Board staff,historical and 2007 analytical, pH, and conduc- <br /> tivity data will be provided on compact disc in the fourth quarter 2007 monitoring report <br /> (Atkinson,2006,personal communication). <br /> During second quarter 2007, effluent samples will be collected monthly and analyzed for <br /> pH, specific conductivity,and VOCs. One quarterly effluent sample will be analyzed for <br /> total dissolved solids. In addition,one set of influent samples will be analyzed for pH, <br /> specific conductivity, turbidity,and VOCs. <br /> 4.0 Works Cited <br /> Atkinson, Ross/Central Valley Regional Water Quality Control Board. 2006.
