Report (WCC, 1991b) the results of analyses of <br /> groundwater samples from Well No. 114-32 , located <br /> approximately 200 feet southwest (upgradient) of LM-60 <br /> and screened in the Upper Horizon, showed 85 µg/L of <br /> TCE and 41 µg/L of PCE. <br /> (2) Section 2. 3.7 of this Work Plan identifies two more <br /> wells in close proximity to LM-60: LM-58 screened in <br /> the Upper Horizon and LM-59 screened in the <br /> Upper/Middle Horizon. <br /> LM-58, in the Upper Horizon, showed concentrations in <br /> May 1988 of 17 µg/L and 35 µg/L of PCE and TCE, <br /> respectively. In May 1991, the results of analyses <br /> showed Well No. LM-58 to have concentrations of 10 Ag/L <br /> and 11 µg/L of PCE and TCE, respectively. <br /> Well No. LM-59, screened in the Upper/Middle Horizon, <br /> showed 1. 1 pg/L and 3 . 3 Ag/L of PCE and TCE, <br /> respectively in May 1988 . In May 1991, the <br /> concentrations in LM-59 were 1 µg/L and 1. 5 µg/L or PCE <br /> and TCE, respectively. <br /> The text on page 2-5, which states that concentrations are <br /> in the area of LM-60 in the middle and Lower Horizons are <br /> anticipated to be in the range of ND to 5 µg/L, appears to <br /> be incorrect. <br /> • Revise the text accordingly. <br /> TABLE 1 <br /> SUMMARY OF ANALYTICAL DATA ON WELLS IN VICINITY OF LM-60 <br /> HORIZON/ <br /> DISTANCE/ .
