alcohol is a suspected field/laboratory contaminant since a similar concentration was also <br /> measured in the QA/QC field blank. <br /> 2.1.6 Surface Water Monitoring <br /> Site run-on and run-off control facilities are designed to effectively channel surface water <br /> to site stormwater/sedimentation ponds. According to the Operations Manager,no <br /> surface water was discharged from the facility during the reporting quarter. During the <br /> second quarter 2009 monitoring period, surface-water monitoring stations FSW-1 and <br /> FSW-2 were sampled on May 4, 2009. Table 2-7 summarizes the current analytical <br /> results of surface water samples collected at the Forward Unit. One VOC <br /> (chloromethane)was detected above the PQL in the sample collected from upgradient <br /> surface water station FSW-2. If should be noted, however,that chloromethane is a <br /> common laboratory contaminant. Given this fact and considering that the sample point is <br /> upstream of the landfill,the VOC is not believed to be attributed to a release from the <br /> landfill. A comparison of upgradient(FSW-2)to downgradient(FSW-1) surface water <br /> samples indicates generally similar inorganic constituent concentrations suggesting that <br /> the landfill operation are not impacting surface water quality. <br /> 2.1.7 Leachate Monitoring <br /> Leachate sumps are inspected for the presence of leachate and observations are recorded <br /> at least weekly by Forward Landfill personnel. If leachate is detected in a sump,it is <br /> pumped into the surface impoundment(W F) for evaporation. During the second <br /> quarter 2009, leachate was observed at holding areas WMU D-89,WMU D-93/94, <br /> WMU D-01, WMU D-02, WMU FU-03, WMU FU-04,WMW FU-05, WMU FU-06, <br /> and WMU FU-08. The other holding areas were reported to be dry by Forward Landfill <br /> personnel. Freeboard at WMU-F ranged from approximately 8.92 feet to 11.67 feet <br /> during the second quarter 2009 monitoring period. Appendix A presents copies of the <br /> leachate logs and the freeboard observation logs. <br /> Leachate samples were collected on a monthly basis and analyzed in the field for pH and <br /> specific conductance. In addition,two retest samples were also collected to verify if 2,4- <br /> dichlorophenol is a potentially new COC. Results of monthly field monitoring <br /> measurements and analytical results for the retests are presented in Table 2-8. As shown <br /> in Table 2-8, neither of the retest results confirmed the presence of 2,4-dichlorophenol in <br /> leachate. Of note,the several SVOCs that were detected have already been recognized as <br /> COCs at the site. <br /> 2.2 SUMMARY <br /> Groundwater quality conditions beneath the Forward Unit during the second quarter 2009 <br /> monitoring period are generally similar to those observed in previous monitoring periods. <br /> During the second quarter 2009 monitoring period, two new historical intrawell <br /> maximum values were measured in samples collected from groundwater monitoring <br /> wells, however,both of the values are for chloromethane, a common laboratory <br /> D:\2009_00ITFA 2Q09.doc <br /> 7 Geologic Associates <br />
