-- Spoil Spring 5 (YSSPG5). This spring was discovered in July 2011, in <br />the main channel that feeds NPDES Pond 014. Its TDS value, 2590 mg /l, <br />indicates that there may be spoil water in this spring. However, the TDS <br />values from Pond 014 this year (680 min., 1233 avg., 1640 max.) <br />indicates that there is very little, if any, spoil water in this pond. <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 />11). This list is composed of CDPHE surface water agricultural use <br />standards (CDPHE, Reg.31, November 2009). <br />Table 12 provides a comparison of surface water quality (including <br />springs) to agricultural standards. This Paradox database generated <br />table does not include the units of concentration (mg /1 or ug /1) for <br />each parameter. The units used for each parameter are the same as those <br />listed on the standards table (Table 11) and are also the same as those <br />used in the water quality reports. The frequency column on Table 12 <br />indicates, in this order: uncensored, that is, the number of exceedances <br />above the Method Detection Limit (MDL) / the number of exceedances <br />between the MDL and the Practical Quantitation Level (PQL) / censored, <br />that is, the number of sample values below the MDL but the MDL was <br />higher than the standard / the total number of 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. Following is <br />a list of standards exceeded this year. <br />Parameter <br />Manganese (CDPHE irrigation) <br />Selenium (CDPHE irrigation) <br />11 <br /># of Sites / # of Excursions <br />6/8 <br />1/1 <br />
