5.0 SURFACE -WATER QUALITY
Samples were collected from active sites 001, 002, 005, 011, 013, 014, 015, 017, 020 and
021 and S -1 during 2006. Analytical results for these surface water samples are presented in Table
C -1 (page C -25). The more frequently measured parameters are presented with the first series of
values with the less frequent measured parameters being in two separate groups after the first group
of parameters in Table C -1. NPDES sites 008, 009, 012, 016, 018, 019, 022, 023 and 024 had no
discharge during 2006 and, therefore, no data are presented.
5.1 TSS
Figures C -5, C -7, C -9, C -11 and C -13 present plots of total suspended solids (TSS) versus
time for the sites 001, 002, 011, 020, 021 and S -1, respectively. A plot was not developed for
NPDES site 014 because only one data point was collected from this site in 2006. The 2006 TSS
values were small and similar to the low range of previously observed values except for a higher
value in March of 2006 from sites NPDES 001 and NPDES 002. Figure C -9 also shows three
values for 2006 with one high and two small TSS values for site 011. Small TSS concentrations for
site 020 and 021 were measured in 2006. Only one TSS value was measured from the limited flow
from NPDES sites 005, 013, 014, 015 and 017 in 2006. A plot was not developed for the one data
point for these NPDES sites. S -1 TSS value was very small in 2006. Plots of flow versus TSS for
the same sites are presented in Figures C -6, C -8, C -10, C -12 and C -14. As expected, a general
increase in TSS for an increase in flow is seen in these plots for the historical data from these sites
with the 2006 data supporting the historical relationship between flow and TSS.
