III IIIIIIIIIIIIIIII ~P~ ~ ~ <br />• Doc Date:12/11/2001 <br />5.0 SURFACE-WATER QUALITY <br />Samples were collected from active sites 001, 002, 011, 017 and S-1 during 2000. <br />Analytical results for these surface water samples are presented in Table C-1 (page C-25), <br />The more frequently measured parameters are presented with the first series of values <br />with the less frequent measured parameters being in two separate groups at the end of <br />Table C-1. NPDES sites 003, 005, 006, 008, 009, 010, 012, 013, 014, 015, 016, 019 and <br />020 had no discharge during 2000 and, therefore, no data are presented. <br />5.1 TSS <br />Figures C-5, C-7, C-9, C-ii and C-13 present plots of total suspended solids (TSS) <br />versus time for the sites 001, 002, 011, 017 and S-1, respectively. The 2000 TSS values <br />• are similar to those previously observed from sites NPDES 001 and NPDES 002, except <br />that there were no high values with the limited peak flows. Figure C-9 shows small TSS <br />values for site 011 in 2000. The TSS concentrations for sites 017 and S-1 were also small <br />in 2000. Plots of flow versus TSS for the same sites are presented in Figures C-6, C-8, C- <br />10, C-12 and C-14. As expected, a general increase in TSS for an increase in flow is seen <br />in these plots for the historical data from these sites with the 2000 data plotting on the <br />lower left portion of the graph due to low flows and small TSS for the limited- peak flows. <br />The highest flow for NPDES sites 001 and 002 were exceptions where the high flows <br />observed small TSS values, which shifted their plot to the right. <br />n <br />LJ <br />5-1 <br />
