High concentrations of sodium,chloride,and sulfate in the ground water <br /> of the Western Valley can render it unsuitable for irrigation and drinking(DWR Bulletin 118-6, 1978). <br /> :3.4 Site Ilydrolzeolouy <br /> Ground water levels in the water-bearing zone at the site are presented in Table 6. Ground water <br /> elevations at the site(measured on June 16,1989) ranged from 26.45 feet below grade in l,dW-1 to 27.34 <br /> feet in NNW-3. Contours of the water table are shown in Figure 6. <br /> TABLE 6 <br /> Ground Water Lrevels <br /> Depth to Ground Water Physical <br /> Monitoring Ground Water References Elevation Observations <br /> Well Date (feet)_ Elevatio —(Mt-)-- -Comments <br /> MW-1 5/23/89 25.93 37.69 11.76 <br /> 6n6/89 26.45 11.24 No odor <br /> MW-2 5/3/89 26.45 3830 11.85 11.26 No odor <br /> 6116189 27.04 <br /> MW-3 5/3/89 26.81 38.58 11.75 No odor <br /> 6/1689 27.34 <br /> m. Note. 'Reference elevation is established in reference to an on site assumed bench mark elevation. <br /> The water table surface is relatively uni€orn with ground water flow being in the northwest direction at <br /> `1 a gradient of about 0.001 footlfoht. <br /> E , <br /> To determine the hydraulic conductivity of the water-bearing materials at the site, slug tests were <br /> performed in all the monitoring wells and evaluated in accordance with methods presented in Bouwer <br /> and Mice, 1976L Results of the slug tests are summarized and are presented in detail in Appendix D. <br />
