Spoil Spring 2 (WSSPG2) was discovered in June 1999. It is located in <br />the main stream channel above Pond 006 adjacent to the oil well. Its TDS <br />plot indicates a decreasing trend. <br />Spoil Spring 3 (WSSPG3) was discovered in September 1999. It is located <br />immediately to the east of Pond 006. Its EC plot indicates an increasing <br />trend. <br />Spoil Spring 4 (WSSPG4) was first sampled in 2003. It contains the <br />combined discharges of the backfilled A and B pits. It is sampled at the <br />outlet of the haul road culvert just above Pond 006. Its TDS plot <br />indicates a decreasing trend. <br />Spoil Spring 5 (WSSPG5) was first samples in June 2006. It is located <br />just above the large culvert that feeds into Pond 016A. It was dry in <br />September. Only two samples have been collected so far. <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 2.005). <br />Table 10 provides a comparison of this year's surface water quality to <br />agricultural standards. This Paradox database generated table does not <br />include the units of concentration (mg/1 or ug/1) for each parameter. <br />The units used for each parameter are the same as those listed on the <br />standards table (Table 9) and are also the same as those used in the <br />water quality reports. The frequency column on Table 10 indicates the <br />number of exceedences out of the total number of samples (i.e., 1/2 <br />indicates one exceedence out of two samples). Below is a summary of <br />standards that were exceeded. Given in parenthesis is the source and use <br />of each standard. Although the CDPHE does not indicate between livestock <br />and irrigation uses in their surface water agricultural standards, they <br />have done so in their similar ground water agricultural standards (see <br />Table 5) For the sake of discussion, SCC chooses to use those ground <br />water use standards classifications (livestock or irrigation) for <br />20 <br />
