The concentrations of field and monitoring <br /> parameters are below established concentration limits; with the exception of well G-1, where a <br /> slight exceedance for magnesium and turbidity was reported during the 1St Quarter monitoring <br /> period. Well G-1 is upgradient of the landfill and serves as the background well; this <br /> exceedance is likely to have been caused by conditions upgradient and not related to the <br /> landfill. <br /> VOCs were detected in the soil gas samples; however, the absence of VOCs in the groundwater <br /> ' suggests that the presence of VOCs in the soil at these concentration levels does not pose a <br /> threat to groundwater at North County. This is consistent with previous years. <br /> ' Secondary leachate sumps at Lined Areas 3 and 4 remain free of leachate. Lined Area 1 is not <br /> provided with a secondary leachate sump. <br /> ' Storm water and surface water samples were not available during this reporting period due to <br /> lack of rainfall. <br /> ' I certify under penalty of perjury that I am familiar with the information submitted in this report, <br /> and to the best of my knowledge the report is true, accurate, and complete. <br />
