Figure 6, Alluvial Aquifer Water Levels, <br />shows ground water levels measured during sampling events over the past 5 years. Water quality <br />samples were collected in October, May and July. The field data collected are presented in Exhibit <br />A, 1997 Field Data. Laboratory analyses aze presented in Exhibit E, 1997 Loadout Area Alluvial <br />Water Quality. These data have been summarized in Table 1, 1997 Ground Water Quality <br />Statistics. <br />The mean field and laboratory pazameter values for the last five years are presented in Tables 6 and <br />7, Historic Loadout Area Alluvial Water Quality Data, Site AP-1 and Site AP-2. Figure 7, EC vs <br />TDS Well AP-1 and Figure 8, EC vs TDS Well AP-2, shows comparison of electrical conductance <br />and the total dissolved solids concentration. <br />• <br /> <br />H19Tti NNU~L RPTHYD0.0 FNL TerraMatrix lnr.'P.O.
