Mr. Tom Horton Project 0939-004.08 <br /> February 14, 1995 <br /> Page 4 <br /> is not a tentative indication of a release from the landfill due to the detection of a similar <br /> compound in the background (or upgradient) monitoring well (MW-1). Pesticides and <br /> herbicides are commonly used for agricultural purposes and may have been used at the <br /> site prior to landfilling operations. <br /> Several inorganic constituents of concern were analyzed, including dissolved metals, total <br /> alkalinity, carbonate, bicarbonate, total organic carbon, cyanide and sulfide. This data <br /> shows that all results were either not detected or below the established concentration <br /> limits. <br /> SURFACE WATER <br /> No flows were observed at the surface water monitoring locations during the fourth <br /> quarter 1994 monitoring event. <br /> GROUNDWATER FLOW DIRECTION <br /> Groundwater levels were measured in monitoring wells MW-1 and MW-2 on <br /> November 28, 1994. Monitoring well LW-1 was inaccessible on November 28, 1994. The <br /> groundwater contour map (see Figure 2) is an approximation of flow based upon data <br /> obtained during previous quarters. Groundwater flow during the fourth quarter 1994 is <br /> inferred to be toward the south. <br /> Please call if you have any questions. <br /> Sincerely, <br /> EMCON <br /> Phillip R. Graham J .
