I <br /> in well EW-2 to 1,600 ug/l in well EW-2 (Figure 13). A comparison of data between July 2004 and . <br /> January 2005 shows that concentrations of total dissolved chromium decreased from 13,000 ug/l to 8.9 <br /> ug/1 in well EW-2 and 1,000 ug/l to<5 ug/I in well EW-3 (Dudek, 2004). <br /> All of the monitoring tubes sampled had detectable concentrations of total dissolved chromium at <br /> concentrations ranging from 24 ug/I in monitoring tube MT-3 to 11,000 ug/l in monitoring tube MT-6. <br /> All of the lysimeters sampled had detectable concentrations of total dissolved chromium at <br /> concentrations ranging from 6.9 ug/1 in lysimeter L-234 to 21,000 ug/I in]ysimeter L-243. <br /> 4' <br /> 4.2 Shallow Wells <br /> 4.2.1 January 2005 <br /> Twenty-four shallow zone monitoring wells and four shallow zone reclamation wells were sampled for <br /> total dissolved chromium in January 2005. Total dissolved chromium was detected in all but four of the <br /> wells sampled. Detectable concentrations ranged from 7 ug/l in monitor well MW-302 to 16,000 ug/l in <br /> monitor well MW-105 (Table 4;Figure 14). A comparison of data between July 2004 and January 2005 <br /> shows that concentrations of total dissolved chromium decreased from 10,000 ug/l to 7,500 ug/l in well <br /> S-2, 1,500 ug/l to 870 ug/l in well S-7, and 4,500 ug/l to 3,000 ug/l in well S-8 (Dudek, 2004). <br /> 4,3 100-Foot Sand <br /> 4.3.1 January 2005 <br /> Six 100-foot sand monitoring wells were sampled for total dissolved chromium in January 2005. Total <br /> dissolved chromium was detected in all of the 100-foot sand wells sampled in January 2005 at <br /> concentrations ranging from 5.4 ug/I in monitoring wells MW-410 to 16 ug/I in well monitoring well <br /> MW-411. <br /> _ Marley Cooling Technologies - 3909-09 <br /> Semi-Annual Groundwater Monitoring Report - Dudek&Associates,Inc. <br /> October 2004/January 2005 -14- April 2005 <br /> Btu, <br />
