VOCs detected include cis-1,2-DCE, <br /> trans-1,2-DCE, 1,1-DCE, TCE and vinyl chloride (VC). VOCs were reported in wells M201), MI IC, TH-9, <br /> and TH-10. Upper flow zone well TH-9 had TCE at 0.9 µg/1, cis1,2-DCE at 1.8 µg/1, and vinyl chloride at <br /> 1.1 µg/1. Intermediate well TH-10 had TCE at 41 µg/1, cis-1,2-DCE at 100 µg/1, and vinyl chloride at 280 <br /> µg/1, and 1,1-DCE at 2.1 µg/1, trans-1,2-DCE at 2.5 µg/l. M20D is located along the western property <br /> boundary,whereas M11C is located along the northern Fox River property boundary. VOCs were not <br /> detected in the following wells: Production wells #6, #7, and# 8; and monitoring wells TH-4, and M7B and <br /> MI.1B. <br /> The time series plots for both sulfate and chloride for TH-7 and TH-8 are anomalous for the first quarter of <br /> 2000. There may be a reporting error. Please check and confirm these data points. This comment was also <br /> noted in the third quarter 2000. <br /> Four new wells were installed per approved Workplan during the week of 19 February 2001. <br /> Well constructions should be evaluated by your consultant to ensure that screened intervals are appropriate. <br /> RWQCB Staff Signature: G" - <br /> Date: 26 FebruM 2001 <br />
