• Heyiar o! the hydrogrsph for Spoil Spring 1 shore the second highest peak floc on record. <br />TD9 wluae haw bean increasing since this spring begin florinq. This is due primarily to <br />m increasing recharge area of upgradimt apoile material as mining progresses and ground <br />rater rasaturation o! the spoils. Spoil Spring 2 azhibite m increasing EC trend. <br />Spoil Sprinqa 3, d, 5, and 7. These springs all east in the Wedge seam mining area in <br />the Little Craesy Creak basin. Spoil Spring 3 drains out of m old backfillad mine pit, <br />and ashibits a relatively level EC trend. Spoil Spring 6 is a spring creak adj scant to <br />Spoil Spring 3 and ashibite a increasing EC trend. Spoil Spring 5 (also knoxn as the <br />PaaCOCO Pond) issues out of mother old mine pit north oP Spoil Spring 3. It displays m <br />increasing EC trend. All these epringe eventually floc into the Nadga Impoundment via <br />Little Grassy Creek. Spoil Spring 7 exists at the upper end of the Nadga Impoundment. <br />Its EC plot displays a decreasing EC trend. <br />Spoil Springs 6 and 10. These epringe exist in the Wolf Creek spoils. Spoil Spring 6 <br />exieta along the northxeet edge o! the apoile and exhibits a decreasing EC trend. 3poi1 <br />Spring 10 rae discovered in 1993. It exists along the eouthraet edge of the apoile in the <br />• vicinity of the Wolf Creak endardrain. It displays on increasing EC trend. <br />Spoil Spring 9. This spring is located in the area immediately upstream of the 008 pond. <br />IC exhibits m increasing EC trend. <br />Comparison of Surfaee Water Quality to Wates Uea Stmdarda.
