~. <br /> <br />SURFACE-WATER QUALITY <br />Samples were collected from active sites S1, 001, 002, 005, 006, 008, 009, 010, <br />011, 013 and 015 during 1996. Analytical results for these surface water samples are <br />presented in Table C-1 (page C-27). The more frequently measured parameters are <br />presented in the first 9 columns with the less frequent measured parameters in the <br />subsequent columns with the remainder on the last page. NPDES sites 003, 012, 014 and <br />016 had no discharges during 1996. Therefore, no data are presented. <br />5.7 TSS <br />Figures C-6, C-6, C-10, C-12 and C-14 present plots of total suspended solids <br />(TSS) versus time for the sites 001, 002, 011, 013 and 015, respectively. The 1996 TSS <br />.-- <br />•~ values are similar to those previously observed except for the February value from sites <br />NPDES 011 and NPDES 015. These two values are significantly greater than other values <br />observed at these two sites but are well within the range of natural TSS values observed <br />from the Trapper drainages. Plots of flow versus TSS for the same sites are presented in <br />Figures C-7, C-9, C-11, C-13 and C-15. As expected, a general increase in TSS for an <br />increase in flow is seen in these plots for 1996. <br />Two TSS values were measured for site S1 (Flume Gulch), one for NPDES 005, <br />three for 008, one for 009 and one for 010 in 1996. These TSS values are found in Table <br />C-1. A figure is not presented for TSS for these sites due to the limited data. Sites 001, <br />002, 005, 009 and 013 were observed to have overall TSS values of less than 122 mg/I <br />during 1996. <br />`~ <br />5-1 <br />
