I ` <br /> 5 <br /> i <br /> n <br /> 1 <br /> s <br /> Introduction <br /> Umetco Minerals Corp. contracted U. S. Environmental Services Inc. to supervise <br /> the drilling of a test boring at their Deremo 2 mine site in San Miguel County, <br /> Colorado. The boring was to be drilled to a total depth of 75 feet in order to <br /> investigate any hydrocarbon contamination in the ground water. If an aquifer <br /> was encountered, a monitoring well was to be installed and the aquifer <br /> monitored for hydrocarbons. However, if no ground water was encountered <br /> within the first 75 feet of the surface the boring was to be plugged and <br /> abandoned (See letter 10/19/99 in Appendix A). Gordon Smith Drilling drilled <br /> the boring. <br /> The location of the test boring (Test Boring MW-1) is shown on Figure 1. <br /> Photograph 1 shows the location of the test boring with respect to the surface <br /> area where contaminated soils were removed. <br />
