r� <br /> i . <br /> Pa <br /> -. g,2 Water Samples <br /> d <br /> A On May 30, 19%,Mjjrray & Associates collected duplicate groundwater samples from all <br /> three monitoring wells. Afield blank, labeled MW-B was also collected as a split sample <br /> uali assurance <br /> from MW-3. MW-B was used as a field blank as a part of normal q ty <br /> procedures. Each sample was evaluated for total petroleum hydrocarbon constituents and <br /> i = <br /> purgeable halocarbons. Subsequent water samples were collected from each of the wells <br /> in November 1990, March 1991, and July 1991. The results of these analyses are <br /> _ summarized in Table 2. Complete analytical reports have been presented in subsequent <br /> quarterly reports and are included in Appendix 1. Included in Table 2 are the relative <br /> State or EPA Action levels for each of the constituents analyzed. <br /> Table 2 <br /> =:s Analytical Results -- Water Samples <br /> rune, 1990 <br /> Sample ID Action <br /> Constituents <br /> uaR.
