OEV |
Total Coliform Single Sample Maximum limit is 240 MPN/100 mL and reported value was 350 MPN/100 mL at EFF-001. |
The operators will ensure that no suspect particulates enter the sample bottle to skew results in the future. Operators will maintain quality treatment and ensure representative samples. |

pH Daily Minimum limit is 6.00 SU and reported value was 5.89 SU at EFF-001. |
In the future, staff will add an alkaline buffering agent to the treatment system well before the effluent pH is affected by biological nitrification. |

11/05/2019 |
Order Conditions |
The nitrate level in the reclaimed water discharge was 29 mg/L. The maximum daily NPDES permit level is 10 mg/L. |
The WWTP treatment process does an excellent job at biological nitrification, but does not currently have a way to denitrify. Until then, nitrate levels in the reclaimed water discharge will remain consistently high. |

pH Instantaneous Minimum limit is 6.0 SU and reported value was 5.74 SU at EFF-001. |
Supplemental alkalinity will be added to the system, and sulfur dioxide feeding will be more closely monitored. |

10/01/2019 |
Order Conditions |
The nitrate level was 31 mg/L when the NPDES permit MDEL is 10 mg/L. |
The plant will have to denitrify in the future to eliminate the nitrate in the discharge. |

09/24/2019 |
Order Conditions |
The nitrate level at REC-001 was measured at 30 mg/L when the NPDES permit level is 10 mg/L. |
In the future, the plant will need to look at ways to denitrify in order to remove nitrate in the effluent. |

Order Conditions |
The reclaimed water discharge nitrate level resulted at 32 mg/L when the NPDES permit maximum daily limit is 10 mg/L. |
The plant will need to denitrify in the future to remove the nitrate in the discharge. |

07/30/2019 |
Order Conditions |
The nitrate result of the District's reclaimed water discharge was 30 mg/L. The NPDES permit limit is 10 mg/L. |
Since there is ample nitrification, the WWTP will need to denitrify in order to reduce nitrate levels in the reclaimed water discharge. We will investigate ways to do so. |

OEV |
Total Coliform 7-Day Median limit is 2.2 MPN/100 mL and reported value was 4.4 MPN/100 mL at REC-001. |
The reclaimed water filters will be shut down and backwashed for an extended period of time, while solids are eliminated from the system to reduce effluent turbidities. |
