In March and April, only water level measurements were taken due to the <br />frozen condition of the wells. The field data collected are presented in Appendix A, 2002 Field Data. <br />Figure 3, Alluvial Aguifer Water Izvels, shows groundwater levels measured during sampling events <br />' over the past 5 years. Water quality samples were collected and analyzed on a quarterly basis, in April, <br />July, and October. As of January 1999, the parameter list for alluvial well sample analysis was reduced <br />to include only major elements and no trace metals. This data has been summarized and is presented <br />in Table 1, 2002 GmundmaterQuakty Statistics. The individual laboratory analyses are presented in <br />Appendix C, 2002 Loadout Area Aluvial Water Quality Analyses. <br />' The mean field and laboratory parameter values for each of the last five yeazs are presented in Tables <br />4 and 5 Historic Laadout Area Alluvial Water Quality Data. Figure 4, EC vs. TDS-Well AP-7, and Figure <br />5, EC vr. TDS-We11AP-2, show comparisons of electrical conductance to total dissolved solids levels <br />' over the last five years. <br />MWH * 7475 Pime Grove Rd, Ste. 109, * SteamLoat Springq Colorado 80477 * (970J 879-6260 <br />N':\Y"ryFirrGdABfT.I++,ulHid.Wpn\IO'1?~3ro?H~EYq Rare <br />11 e6/03~ <br />
