FIRST QUARTER 2008 GROUNDWATER TREATMENT FACILITY MONITORING REPORT <br /> FORWARD LANDFILL WDR ORDER NO.R5-2003-0080 <br /> Under WDR Order No. R5-2003-0080,influent sampling for pH,specific conductivity, <br /> turbidity, and VOCs is performed semiannually. Influent samples are collected from a <br /> sample port in the header pipe adjacent to the air stripper. Semiannual influent monitoring <br /> was not performed during first quarter 2008. <br /> A compact disc containing historical influent and effluent analytical,pH,and conductivity <br /> data from August 1994 to December 2007 was provided in the Fourth Quarter 2007 <br /> Groundwater Treatment Facility Monitoring Report(CH2M HILL,2008). In accordance with <br /> a conversation with CV Water Board staff,historical and 2008 analytical,pH,and conduc- <br /> tivity data will be provided on a compact disc in the fourth quarter 2008 monitoring report <br /> (Atkinson,2006,personal communication). <br /> During second quarter 2008,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.
