<br />APPENDIX I <br /> <br />Trapper Mine Annual Groundwater Report <br />Histories of sites without analytic results <br />Site GA-1 <br />Well site was drilled November iL, 1974. Total drill hole depth is 177 <br />feet. Since May 1975, Trapper has been unable to obtain sufficient water for <br />analyses. The largest sample volume to be obtained was 1 liter in April 1976. <br />The well was bailed September 27, 1982 by a commercial water well service. Due <br />to insufficient water, a sample could not be obtained in December 1982. <br />Site GZ-1 <br />Well site GZ-I was drilled February 1979. The total drill hole depth was <br />398.9 feet. Water levels were obtained in February and March 1979 at - 396 feet. <br />Since March ]979, electric water level indicators have not detected a static <br />water level. <br />GRR sites <br />Under a 1980 cooperative agreement between Trapper Mine and Northern Coal <br />Inc., Northern agreed to monitor and maintain the three wells ~GRR-1, 2 and 3) <br />according to frequencies and parameters specified by the CMLRD. The data pre- <br />sented are the results of Northern's efforts until December 1982. Trapper Mine <br />is resuming monitoring responsibilities for these sites per Table 4.8-12 of our <br />permit. <br />Site P-5 <br />Well site P-4 was monitored as P-5 in 1981. A map placement error was the <br />reason. Map corrections and stenciled well identifiers will prevent this error <br />in the future. <br />WSH/js <br />(/28/83 <br />
