<br />conducted. <br />The Division reviewed water quality data and compared it to <br />previous years' data, and predictions in the 'PHC. <br />Water levels in the Wadge overburden have been fairly <br />constant since 1984, exhibiting seasonal fluctuations. <br />TDS has stabilized in Wadge overburden well 008-77-58, <br />but continues to exhibit a slight increase over time in <br />well 008-79-6, also Wadge overburden. <br />The Foidel Creek alluvium also exhibits seasonal <br />fluctuations for the period of record. Seasonal <br />variation is apparent in field conductivity measurements <br />in Foidel Creek alluvial well 008-AV-1, but an increasing <br />trend is evident at 008-AV-2. TDS at 008-AV-2 hit an all <br />time high (1970 mg/1) on 3/31/95. CYCC notes that they <br />will continue to monitor the direction of this trend, and <br />the Division will do so also. <br />Water levels in the spoils wells show a peak in the <br />Spring of 1995, which corresponds to heavy precipitation <br />recorded, but exhibit normal seasonal variation <br />otherwise. TDS values are within established ranges. <br />Flow values recorded on Foidel Creek and Middle Creek <br />show typical seasonal variation, and correspond to the <br />heavy precipitation recorded in the Spring. TDS at Site <br />29 shows a decreasing trend after peaking in the late <br />1980's to early 1990'5. TDS at Site 700 appears to be <br />decreasing, but is still within the historic range for <br />that site. Site 900, which is upstream of the mine, <br />shows a steady increase since 1975. <br />In conclusion, monitoring results to date are within predictions in <br />the PHC, and do not warrant reevaluation of the PHC at this time. <br />The Division noticed a few minor problems with CYCC's graphic <br />representation of data, which should be corrected. <br />9. Figures 8, 9, 10, 18, and 19 should be updated to include <br />data through the 1995 water year. Values for spoils well <br />008-SP-SA are graphed, but not for 008-SP-4B. It would <br />be helpful if 4B were graphed as well. Please make these <br />changes in future AHR's. <br />If you have any questions concerning the above, please call. <br />Sincerely, <br />ose h J Dudash <br />nvironmental Protection Specialist <br />C:\WP51\MINE3\1995AHR <br />
