Is there a summary of the monitoring X <br /> Standard results indicating any changes made <br /> Provisions or observed since the previous annual <br /> (1993,1997,2000) report? <br /> X <br /> v.

Include increasing levels of inorganics. 2nd Q should have also included <br /> Appendix 1 —Progress of Corrective Action Measures as shown in 1st Q report. Please ensure subsequent <br /> transmittal letters and reports include this information. <br /> Comment Ld. =Table 1 shows statistically high concentration limits for chloride in MW-5. Other wells <br /> and constituents also appear to be high. Based on our statistical analysis, using the same parameters <br /> identified in Appendix D, we have calculated much lower concentration limits that are more realistic. We <br /> screened out outliers as recommended by SANITAS. The Counties database also shows that outliers were <br /> not used in your statistical analysis so we do not understand why your limits as so high. As stated in <br /> previous review comments on monitoring reports, the data supports the conclusion that leachate is impacting <br /> MW-5 due to obvious landfill leachate increases in TDS,bicarbonate, chloride and decreasing pH levels. <br /> We request that a evaluation monitoring program(EMP)be proposed to delineate the nature and extent of <br /> impacts at MW-5 (chloride,bicarbonate, TDS; see attached time series charts) and changes evident in MW-4 <br />
