Kerr Coal - 2004 Annual Hydrology Report February, 2005 <br />5.0 LOADOUT AREA ALLUVIAL GROUNDWATER <br />Two alluvial wells (AP-1 and AP-2) were monitored for field measurements in October 2003 and then on a <br />monthly basis from March through September 2004. No field measurements were made in March and in <br />April only water level measurements were taken due to the frozen condition of the wells. The field data <br />collected are presented in Appendix A, 2004 Field Data. Figure 3, Alluvial Aquifer iP~ater Lcve1, shows <br />groundwater levels measured during sampling events over die past 8 yeazs. Water levels have returned to <br />historic levels in both wells following a low water (drought) yeaz in 2002. <br />Water quality samples were collected and analyzed on a quarterly basis in October 2003 and in May and July, <br />2004. As of January 1999, the parameter list for alluvial well sample analysis was reduced to include only <br />major elements and no trace metals. This data has been summarized and is presented in Table 1, 2004 <br />Groundwater Qua&ty Statisttir. The individual laboratory analyses aze presented in Appendix D, 2004 Loadout <br />Area Alluvial Water Quality Analyses. <br />The mean field and laboratory parameter values for each of the last 8 years aze presented in Tables 4 and 5 <br />Hi,rtorzc Loadout Area Alluvial IY/aterQua/r'ty Data. Figure 4, EC vr. TDS-Well AP-1, and Figure 5, EC us. TDS- <br />WeIIAP-2, show comparisons of electrical conductance to Total Dissolved Solids (TDS) levels over the last 8 <br />years. These general water quality indicators remained consistent during this monitoung period in AP-2 <br />although the readings aze a little more erratic than in the past. In AP-1, electrical conductivity has dropped <br />slightly in 2004 over previous years though a TDS drop is not as evident. <br />
