Landflll- MSW Permit No. 144 <br />Groundwater Investigation Report and Future Activities <br /> <br />Dear Mayor Clifford: <br /> <br />We have reviewed the report entitled Groundwater Investigation. City of Paris Stillhouse Road Landfill. <br />MSW Permit No. 144, dated September 1997. The document was submitted under a cover letter dated <br />October 6, 19.97, signed by Mr. A. Richard Smith, Senior Hydrogeologist, BMCON, Fort Worth, Texas. <br />Thank you for the report. <br /> <br />/'......\ <br />() <br /> <br />We are glad to read about improvements in ~nal cover and drainage, and are interested in the possibility <br />that the volatile organic compolU1ds (VOCs) detected may be related to landfill gas. Please implement the <br />recommendations made in the report for further activities at the site, with the following modifications: <br /> <br />Ensure that the methane"gas survey adequately covers the entire site. In addition to concentrating <br />on the southeast part of the site, please also focus on the area arolU1d piezometer P-l1, which has <br />shoM! the highest overall concentrations ofVOCs in groundwater samples taken during 1996. <br /> <br />· Install replacement piezometer P-10A., and the proposed new piezometers P-13 and P-14 by the <br />end of the first quarter of 1998. (Note; In Figure 18 of the report, the proposed piezometers were <br />designated .P-12 and P-13; P-12 already exists, therefore the new piezometers should be <br />designated P-13 and P-14.) . <br /> <br />As soon as the replacement piezometer and new piezometers are ready, sample all monitor wells <br />(MW-l; 2, 3, 4, 5) and piezometers (P-I, 2, 3, 4, 5, 6, 9, lOA, 11, 12, 13), and the leachate from <br />MW -4A. Analyze samples for VOCs and ammonia as proposed. . <br /> <br />· Continue semiannual monitoring of all wells and piezometers in which VOCs are detected during <br />the first event in 1998. After additional infonnation is obtained and further reconunendations are <br />made, the monitoring schedule may be revised. <br /> <br />I' . <br />() Continue leachate extraction from MW-4A <br /> <br />P.O.
