Spool Spring 5 (also known as the PeaCOCo <br />• Pond) issues out of another old mine <br />it th o <br />no f S <br />oil S <br />rin <br />3 It di <br />l <br /> p r p <br />p <br />g <br />. sp <br />ays an <br /> increasing EC trend. All these springs eve ntually flow into the Wedge Impoundment vva <br /> Little Grassy Creek. Spoil Spring 7 exists at the upper end of the Wedge Impoundment. <br /> Its EC plot displays a decreasing EC trend. <br />- Spool Springs 6 and 10. These springs exist in the Wolf Creak spoils. Spoil Spring 6 <br />exists along the northwest edge of the spoils and exhibits a decreasing EC trend. Spoil <br />Spring 10 was discovered in 1993. It exists along the southwest edge of the spoils in the <br />vicinity of the Wolf Creek undezdrain. It displays on decreasing EC trend. <br />- Spoil Spring 9. This spring is located in the area immediately upstream of the 000 <br />pond. It exhibits an increasing EC trend. <br />Comparison of Suzface Watez quality to Water Use Standards. SCC has Compiled a list of <br />surface water standazds for agzicultuzal uses (Table 9). This list is composed mostly of <br />CDOH suzface water agzicultuzal use standards as of March 1999 (sea footnotes B, C, and F <br />• on that table), although other agency standards have been used i£ the CDOH has no suzface <br />water agzicultuzal standard for a particular parameter (all other footnotes). <br />Table 30 provides a comparison of surface water quality to agricultural standards. This <br />Paradox database generated table does not include the units of concentration (mq/1 or <br />ug/1) foz each parameter. The units used for each parameter aze the same as those listed <br />on the standards table (Table 9) and are also the same as those used in the water quality <br />reports. Tha frequency column on Table 10 indicates the number of exceedences out of the <br />total number of samples (i.e., 1/2 indicates one exceedence out of two samples). Below vs <br />a summary of standards that were exceeded. Given in parenthesis ie the source and use of <br />each standard. Although the CDOH does not indicate between livestock and irrigation uses <br />vn they surface water (SW) agricultural standards, they have done so in their similar <br />ground water (GW) agricultural standards (see Table 5). Por the sake of discussion, SCC <br />chooses to use those ground water use standards for surface water use evaluation. <br />Parameter Number of So tes <br />aluminum (CDOH, Gw, livestock) 3 <br />• pH (CDOH, GW, irrigatoon) 7 <br />fluoride (CDOH, GW, irrigation) 1 <br />)~ <br />
