SECOND QUARTER 2006 GROUNDWATER TREATMENT FACILITY MONITORING REPORT <br /> FORWARD LANDFILL WDR ORDER NO.135-200330080 <br /> 3.0 Influent and Effluent Monitoring <br /> Under WDR Order No.R5-2003-0080,effluent samples are analyzed as follows: <br /> • Monthly for pH,specific conductivity,and VOCs <br /> • Quarterly for total dissolved solids <br /> • Annually for dissolved inorganics <br /> All parameters other than dissolved inorganics were analyzed during second quarter 2006. <br /> Figure 1 shows the effluent monitoring location.Table 2 presents the results of the effluent <br /> monitoring performed during second quarter 2006.Appendix A contains the effluent <br /> monitoring field sampling logs and laboratory results for second quarter 2006. <br /> The current WDRs stipulate that the concentration limit for VOCs in the effluent is <br /> nondetect. No VOCs were detected in the GTF effluent samples collected during second <br /> quarter 2006. <br /> TABLE 2 <br /> Effluent Monitoring Results <br /> Forward Landfill Groundwater Treatment Facility Monitoring Report, Second Quarter 2006 <br /> Analysis Date Parameters Units Results <br /> Field Parameters' <br /> 4/26/06 pH pH units 7.6 <br /> Conductivity µmhos/cm 525 <br /> 5/11/06 pH pH units 7.5 <br /> Conductivity µmhos/cm 484 <br /> 6/3/06 pH pH units 7.8 <br /> Conductivity µmhos/cm 660 <br /> Laboratory Analyses° <br /> 4/26/06` All VOCs pg/L Nondetect <br /> 5/11/06` All VOCs pg/L Nondetect <br /> Total Dissolved Solids milligrams per liter 432 <br /> 6/3/06° All VOCs µg/L Nondetect <br /> 'Field parameters were analyzed using a calibrated Horiba U-10 water quality meter. <br /> bVOCs were analyzed using U.S. Environmental Protection Agency(EPA)Method SW8260B.Total dissolved <br /> solids were analyzed using EPA Method 160.1. <br /> `Only EW-1 was operational when this sample was collected. <br /> °Both extraction wells were operational when this sample was collected. <br /> Notes: <br /> pg/L = micrograms per liter <br /> µmhos/cm = micromhos per centimeter <br /> RDD/062060D08(CAH3547.DOC) 3 <br />
