GVlch. It also ezhibite seasonal vaziatlone typical o! prevlouely mentioned monitoring <br />wells. <br />Well WDAL11, situated immdiately above the NPDES 005 pond, ie aormally dry. Wall WSAL12 <br />is situated nazt to the lover Sago Creek flume site (9W-92W-EYA). Well WSAL13 ie situsied <br />on a tributary to Saga Creak (NPDES 009 Gulch). Wolle YSAL1, 3, 8, and 12 aza old United <br />States Geological Survey alluvial calla situated along upper Saga Crwk and are also a <br />pazt of SCC's Yoaet Mine monitoring network. Most of these calls exhibit typical aeaeonal <br />veriations. Seasonal variation at Wall YSAL3 is masked by local recharge from adjacent <br />beaver dsms Ln Saga Creek. <br />Wedge Overburden. Moat Wedge overburden wells ezhibit seasonal variations typical of the <br />owrburQan aquifer (i.a., shallow in the spring or summer, deepening in the lnll). All <br />rolls a:hibited the highaet rater levels on record this year due to high precipitation. <br />Wadga Coal. Wedge coal cells ezhibit the same typical seasonal variations ae the previous <br />aquifers diecuaeed. Dua to for aquifer tranamieaivitiae (range 0.07 to 0.36 ft2/day), <br />rater sampling may mask normal rater level fluctuations. Wells WW3, 14 and 17 all <br />• exhibited this year the highest rater lewla on record due to high precipitation. <br />Wolf Creek Coal. Both calla exhibit the came eeaaonal wriability ae noted previously. <br />Wall WWC3 exhibited this yeas the highest rates levels since 1981, chile Well WWC17 <br />exhibited this year the highest rates lavala on record. Both inereaeea are again due to <br />high precipitation. <br />Ground Water Laval S•••~•~~~ Host aquifers at Seneca 2I-W ezhibit a typical eeneonal <br />fluctuation. Water levels aze highaet after the aprinq runoff, rhich raUazgea the <br />aquifer. often, bedrock aquifers exhibit a lag time betraen spring runoff and highaet <br />water levels. Water levels than decrease ae late Bummer or fall approaches. Most <br />bedrock rolls exhibited rater levels this yaaz that rare the highest on record due to high <br />precipitation. <br /> Water Quality. Table 3 (Appendix A), Summary of Ground Water Monitoring Wells, describes <br /> the cells that were sampled, the sample frequenry during this year, and site <br /> characteristics.
