CO 50477 <br />Mr. Craig Springer <br />Bear Coal Company <br />Somerset, Colorado 81434 <br />Dear Craig: <br />April 18, 1985 <br />008/89.8$80 <br />Enclosed please find the compiled analytical data for Bear Coal's 1984 <br />Quarterly water samples from Sites Alluvial Well #1, #2, and #3. I <br />also included average values from the 1983 samples from the above <br />sites. <br />The average values for the 1984 data correlates very well with the <br />1983 data. Even with seasonal variations in the water quality for <br />both years, very little change in water quality occurred between 1983 <br />and 1984. <br />As in 1983, there is still a problem with high trace metal <br />concentration in the ground water. This is due to the fact that the <br />metals are analyzed as total recoverable and not as dissolved as <br />normally done with ground water. When samples contain large amounts <br />of sediment, as is the case with Bear Coal's samples, metal ions <br />adsorbed to the sediment particles go into solution when nitric acid <br />is added to the sample as a preservative. This problem can be <br />corrected by analyzing the samples for dissolved metals. <br />If you have any further questions, please call. <br />Sincerely, <br />BOOKCLIFFS COMMERCIAL LABORATORIES <br />~~ V' ~~~ <br />Ralph V. Poulsen <br />Director <br />RVP:ju <br />Enclosure <br />
