Surface Water |
The bacteria levels in receiving water exceeded the 320 colony forming units (cfu)/100 mL E. coli statistical threshold value (STV; not to be exceeded by more than 10% of samples during a calendar month) at all downstream receiving water sites, RSW-002 (Miller Park), RSW-003 (Westin) and the alternate RSW-004 site (RSW-GSB; Garcia Bend). |
Effluent E. coli from Pioneer Reservoir EFF-006 and the Combined Wastewater Treatment Plant (CWTP) EFF-002 to which the receiving water limitations apply both had non-detects for E. coli, indicating that the receiving water limitation was not exceeded due to the treated CSS discharges.
However, E. coli levels in the untreated discharge from EFF-004 exceeded the STV, and the downstream sample at RSW-003 also exceeded the STV which is a receiving water violation for that one sample. |

Surface Water |
The turbidity increase from the upstream (RSW-001; Delta King) to downstream (RSW-002; Miller Park) receiving water exceeded the receiving water limitation of more than 1 NTU where natural turbidity is between 1 and 5 NTUs with an increase from 3.10 NTU upstream to 5.48 NTU downstream. |
Turbidity data from the downstream United States Geological Survey (USGS) gauge at Freeport showed a trend of low turbidity (<5 NTU) at the beginning of the storm and increasing to over 40 NTU after the storm. The turbidity increase from upstream to downstream of EFF-006 discharge was not evident in later samples collected during the discharge event (upstream and downstream of EFF-002 discharge, or upstream and downstream of EFF-004 discharge) and was likely due to inputs other than CSS discharge. |
