5.0 SURFACE -WATER QUALITY <br />Samples were collected from active sites 001, 002, 011, 017, 018, 020 and S -1 during 2014. <br />Analytical results for these surface water samples are presented in Table C -1 (page C -24). The more <br />frequently measured parameters are presented with the first series of values. The less frequent <br />measured parameters are in two separate groups and shown after the first group of parameters in <br />Table C -1. NPDES sites 008, 009, 019, 021, 022, 023 and 024 had no discharge during 2014 and, <br />therefore, no data are presented. <br />5.1 TSS <br />Figures C4, C -6, C -8, C -10 and C -12 present plots of total suspended solids (TSS) versus <br />time for the sites 001, 002, 011, 017, 018, 020 and S -1. The 2014 TSS values were small and similar <br />to the low range of previously observed values. S -1 TSS value was very small in 2014. Plots of flow <br />versus TSS for the same sites are presented in Figures C -5, C -7, C -9, C -11 and C -13. As expected, a <br />general increase in TSS for an increase in flow is seen in these plots for the historical data from these <br />sites with the 2014 data supporting the historical relationship between flow and TSS. <br />5.2 CONDUCTIVITY <br />The conductivity versus time plot for site NPDES 001 shows a similar, but slightly higher, <br />range of conductivity in 1998 through 2014 to the range observed over the previous few years (Figure <br />C -14). The observed 2014 conductivity data plots within the historical range in conductivity for <br />Johnson Gulch (00 1) for the low flow rates (Figure C -15). <br />Figure C -16 presents conductivity concentrations versus time for NPDES site 002. The <br />upper range in conductivity in 2011 through 2014 was slightly less than the upper range for the <br />Trapper Mining Company 5 -1 <br />2014 Annual Report <br />
