OEV |
Total Coliform 7-Day Median limit is 23.0 MPN/100 mL and reported value was 28 MPN/100 mL at EFF-001. |
The contact chamber was drained and cleaned. Adding a new sample port with reduced flow and turbulence should significantly reduce the chance of surface contaminants or turbulence disturbing the sample when grabbed. A small top wall section was removed to facilitate even surface flow and eliminate stagnant water. |

OEV |
Total Coliform 7-Day Median limit is 23 MPN/100 mL and reported value was 36 MPN/100 mL at EFF-001. |
Increased the chlorine feed rate from 4.00 mg/L to 4.50 mg/L. All other parameters and constituents look good, turbidity has been less than one, free chlorine has been consistently between 1.00 and 2.0 mg/L. We are tracking all parameters to resolve issue. |

Total Coliform 7-Day Median limit is 23 MPN/100 mL and reported value was 25 MPN/100 mL at EFF-001. |
Working through potential sources that could cause elevated total coliform samples in treatment processes. The ballast pond and chlorine contact chambers were drained and cleaned completely. Total and free chlorine is being tracked during coliform sampling. Also reached out to Pace Analytical lab to confirm all QA/AC is being followed. |

OEV |
Total Coliform 7-Day Median limit is 23 MPN/100 mL and reported value was 130 MPN/100 mL at EFF-001. |
Increased flows from heavy rain has increased the hydraulic loading on the plant. The sudden increase may have caused a negative effect on the treatment process. Corrective action was to increase the dosage to the contact chamber from 4.0 mg/L to 4.5 mg/L and put an additional pressure filter online to increase filtration efficiency. |

Total Coliform 7-Day Median limit is 23.0 MPN/100 mL and reported value was 71 MPN/100 mL at EFF-001. |
We collected additional coliform samples as soon as we was notified of the positive sample. We wanted to demonstrate / confirm we was in compliance with our discharge permit. There was no further violations beyond this specific sample.
In addition plant personnel reviewed sample collection protocols and awareness of ambient conditions when collecting samples. |
