- Spoil Springs 3, 4, S, and 7. These springs all exist in the Wadge <br />seam mining area in the Little Grassy Creek basin. Spoil Spring 3 <br />drains out of an old backfilled mine pit, and exhibits a decreasing EC <br />trend. Spoil Spring 4 is a spring creek adjacent to Spoil Spring 3 and <br />exhibits a stable EC trend. Spoil Spring 5 (also known as the PeaCoCo <br />Pond) issues out of another old mine pit north of Spoil Spring 3. It <br />displays an increasing EC trend. All these springs eventually flow into <br />the Wadge Impoundment via Little Grassy Creek. Spoil Spring 7 existed <br />at the upper end of the Wadge Impoundment until the summer of 2002, when <br />regrading of the pond shoreline buried this spring. Its EC plot <br />displayed a stable EC trend. <br /> - Spoil Springs 6 and 10. These springs exist in the Wolf Creek spoils. <br /> Spoil Spring 6 exists along the northwest edge of the spoils and <br /> exhibits a stable EC trend. Spoil Spring 10 was discovered in 1993. It <br /> exists along the southwest edge of the spoils in the vicinity of the <br /> Wolf Creek pit u nderdrain, and is normally sampled at the haul road <br /> culvert downstream. It displays on stable EC trend. <br />Additional sampling was performed in the Spoil Spring 10 channel this <br />and last year. l0A is located 1200 feet above the haul road culvert and <br />is at the toe of the Wolf Creek pit underdrain. l0s is located in the <br />main channel 3000 feet above the haul road culvert. loc is a developed <br />{PVC pipe) spring located adjacent to lOB. Analyses of samples from <br />these three sites may be found after Spoil Spring 10 in Appendix D. <br />- Spoil Spring 9. This spring is located in the area immediately <br />upstream of the 008 pond. It exhibits an increasing EC trend. <br />Comparison of Surface Water Quality to Water Use Standards. SCC has <br />compiled a list of surface water standards for agricultural uses (Table <br />9). This list is composed of CDOH surface water agricultural use <br />standards (CDOH, Reg.31, October 20011 <br />Table 10 provides a comparison of surface water quality data this year <br />to agricultural standards.
