parameter data are presented on time series concentration plots in Appendix G. For VOCs, only <br /> those VOCs with second quarter 2006 detections in evaluation monitoring wells were plotted. <br /> Historical data from the evaluation monitoring wells were evaluated for temporal trend using <br /> Sen's Slope trend analysis. Graphs of the Sen's Slope analyses are included in Appendix G. The <br /> only constituent to exhibit an increasing trend according to Sen's Slope analysis was sulfate at <br /> MW-2. Sen's Slope analysis identified decreasing trends in barium at MW-2, chloride at MW- <br /> IA and MW-2,and temperature at MW-IA. <br /> ' Eight VOCs were detected above reporting limits in the samples from MW-IA and MW-2,which <br /> are screened in waste material. Table 2.3 presents the VOCs detected at MW-IA and MW-2 <br /> ' during the second quarter 2006 monitoring event. There were no VOCs that exhibited an <br /> increasing trend during the second quarter 2006 according to Sen's Slope analysis. <br /> 3 <br />
