- 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 underdrain, and is normally sampled at the haul road <br />culvert downstream. It displays a decreasing EC trend. <br />Spoil Spring l0A is located 1200 feet above the haul road culvert and is <br />at the toe of the Wolf Creek pit underdrain. It displays an increasing <br />EC trend. <br />- Spoil Spring 9. This spring is located in the area immediately <br />upstream of the 008 pond. It exhibits a slightly increasing EC trend (SF <br />= 0.5). <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 CDPHE surface water agricultural use <br />standards (CDPHE, Reg.31, December 2005). <br />Table 10 provides a comparison of all surface water quality data this <br />year to agricultural standards. This Paradox database generated table <br />does not include the units of concentration (mg/1 or ug/1) for each <br />parameter. The units used for each parameter are the same as those <br />listed on the standards table (Table 9) and are also the same as those <br />used in the water quality reports. The frequency column on Table 10 <br />indicates the number of exceedences out of the total number of samples <br />(i.e., 1/2 indicates one exceedence out of two samples). Below is a <br />summary of standards that were exceeded. Given in parenthesis is the <br />source and use of each standard. Although the CDPHE does not indicate <br />between livestock and irrigation uses in their surface water <br />agricultural standards, they have done so in their similar ground water <br />agricultural standards (see Table 5). For the sake of discussion, SCC <br />chooses to use those ground water use standards classifications • <br />(livestock or irrigation) for surface water use evaluation. <br />18 <br />
