G80~006 ~ PaQe IS <br />5.0 LOADOUT AREA ALLUVIAL GROUNDWATER <br />^ Two alluvial wells (AP-1 and AP-2) were monitored for groundwater levels on a weekly basis <br />from March through June, and monthly from July through October. Figure 6, Alluvial <br />Aquifer Water Levels, shows groundwater levels measured during sampling events over the past <br />5 years. Water quality samples were collected in October, May and July. The field data <br />collected are presented in Appendix A, 1999 Field Data. Laboratory analyses are presented in <br />' Appendix E, 1999 Loadout Area Alluvial Water Quality Analyses. These data have been <br />summarized and are presented in Table 1, 1999 Groundwater Quality Statistics. <br />' The mean field and laboratory parameter values for each of the last five years are presented in <br />Tables 6 and 7, Historic Loadout Area Alluvial Water Quality Data. Figure 7, EC vs. TDS- <br />Well AP-1 and Figure 8, EC vs. TDS-Well AP-2, show comparisons of electrical conductance to <br />' total dissolved solids levels over the last five years. <br />1 <br /> <br /> <br />1 <br /> <br /> <br />1 <br /> <br /> <br /> <br /> <br />' Montgomery Watson * ('.O.
