I <br /> kw) KLFINFELDER <br /> 5 RESULTS <br /> 5.1 GROUNDWATER GRADIENT <br /> Initial depth to water measurements were conducted prior to sampling on November 29, <br /> 1988, and are presented in Appendix A on Table 3, Ground Water Level Measurements. <br /> The reference point for these measurements is a survey'.point on the north side of the tap <br /> Of .PVC casing for all three monitoring wells. Elevations for these reference points are <br /> shown in Appendix A on Table 1. <br /> The measured static water levels indicate the ground water`flows to the northeast with a' <br /> __.hydrayulic gradient of 0.069 percent (see Plate 2, Ground Water Gradient Map). a �~ <br /> ` <br /> 5.2 CHEMICAL ANALYTICAL RESULTS <br /> The water samples collected on November 29, 1988, from the three ground water <br /> monitoring wells, were analyzed for' halogenated (volatile.organics by .EPA Method 601 <br /> The laboratory results indicate that concentrations of concerned parameters, including <br /> chloroform, are below detection limits. <br /> A water sample was collected and analyzed for EPA Method 501 for quality <br /> assurance/quality control from the water introduced in the wells during well construction_ <br /> The water used was ` from a"'city*; fixe hydrant. " Chloroform (3.9 ug/1)*; <br /> bromodichloromethane (18 ug/l)*, trichloroethane-(17 ug/1)*, and bromoform (48 ug/l)` <br /> were present in this water sample. A possible explanation for the measured concentrations <br /> Of these constituents may be a result of the chlorination of city water supplies. The <br /> constituents reported in this sample are members of the trihalomethane group, which-is a <br /> by-product o£chlorination. <br /> Laboratory data sheets are available for review in Appendix C. <br /> *ug/l * micrograms/liter : <br /> 156-88-2362 8 <br />
