Is there an evaluation of the <br /> effectiveness of the leachate <br /> monitoring/control facilities? <br /> Standard w. is there a discussion about the <br /> Provisions annual LCRS testing and a <br /> (April 2000, comparison to earlier testing? <br /> Sept.2003)or <br /> check WDRs <br /> Violations Noted? (check one) Yes—X— No <br /> If Yes, check all issues that apply and provide comments: <br /> Comments (to be entered into CIWQS/Geotracker): <br /> Incomplete transmittal letter Groundwater and vadose zone impacts continue at this <br /> Incomplete report site. Discharger has submitted an EFS and is <br /> Inadequate monitoring program recommendiniz additional extraction wells to control <br /> New release and remove source of LFG. Staff recommends that <br /> Inadequate response to evidence of a release additional LFG extraction wells be installed across the <br /> WDRs violation northern boundary. Additional gas probes need to be <br /> Other (explain in comments) installed along northern boundary. GW samples shall <br /> be collected after 5 NTU value is achieved. <br /> Additional Comments and Recommendations: <br /> 21. 15 VOCs were detected in gas probe GW-2, which is vicinity of MW-8. Gas probes GW-1 and GW-3 also <br /> reported 12 VOCs and 21 VOCs, respectively. Probes GW-6 reported six VOCs but had the highest Freon 12 <br /> concentration of 18,000 ppb/v. GW-7 reported 20 VOCs. Methane is not being reported at the perimeter <br /> probes, which satisfies CalRecyle regulations. <br /> However, LFG is present at the perimeter and is the suspected carrier of the VOCs reported. No probes exist <br /> along the northern boundary of the LF. Staff has requested a minimum of two probes be installed to monitor <br /> migrating gas. Well MW-1 lA shows signs of LFG impacts offsite. Groundwater indicates LFG is migrating <br /> northeastward. VOCs detected in gas samples similar compounds detected in groundwater. The nearest gas <br /> probes to well MW-11 A are GW-6 and GW-7, both which contained elevated carbon dioxide gas compared to <br /> other gas probes. <br />
