Settleable Solids Monthly Average limit is 1.0 ml/L and reported value was 1.1 ml/L at M-001B. |
Based on settleometer testing the problem was determined to be the formation of straggler floc in significant amounts. Straggler flocs are slowly settling floc particles suspended in the clear liquid, or supernatant, above the settled sludge mass. We began dosing the clarifier feed with cationic polymer on April 23 and as a result we brought the settleable solids results below the maximum limits on April 25. We also reduced wasting because high food to microorganism ratio, F:M, is considered a possible cause of straggler floc formation. |

Settleable Solids Weekly Average (Mean) limit is 1.5 ml/L and reported value was 2.0 ml/L at M-001B. |
At M-001B, Chiquita WRP Effluent the settleable solids result was 2.0ml/L on Wednesday 8/30/23, and was the only sample taken that week ending on 9/2/23. The average weekly violation is >1.5ml/L. We clean our Secondary Effluent Flow Equalization Tank (FET) on Wednesdays each week. August 30, 2023 was one of those Wednesdays. Our protocol calls for recirculation of secondary effluent from the FET to the Plant Effluent Outfall Structure and back to the FET using pumps set up for this procedure. The intent is to remove any sediments or films that may have accumulated from the pipe and send them to the FET. Apparently, a grab sample was taken while this action was underway. While this water doesn't leave the plant outfall during the recirculation step it is possible to sample from this water. In the future, we will take steps to make sure no sample is taken during this cleaning operation so that there will be no reoccurrence of this exceedance. |

DMON |
Based on a conversation with Mr. Keith Yeager on June 5, 2020, Mr. Yeager determined that the previous policy of acceptance of non-sampling events due to staff hours of labs Monday through Friday is no longer valid. Therefore, for May, there were deficient monitoring events the week of May 17th through the 23rd and May 24th through 30th at M-001B. SOCWA advised member agency staff of the update on June 5, 2020. |
SOCWA will work with the Regional Board on updated language in the permit to match the staffing at the facilities when facilities are reclaiming all flows for beneficial reuse. |

Deficient Reporting |
For the week of March 1, 2020, SOCWA only reported four out of the five required monitoring results for TSS, SS, pH, and CBOD for monitoring location M-001B. Note: SOCWA reported zero flow from monitoring location M-001B on March 5, 2020. |

On June 5, 2020, Mr. Yeager determined that there were monitoring event violations the week of February 16, 2020 and February 23, 2020 due to only four of five samples taken during those weeks at monitoring location M-001B. |
I explained to Mr. Yeager that the laboratory at that location is only staffed Monday through Friday which prevented the additional sampling and analysis over the weekend. SOCWA will work with the Regional Board on updated language in the permit to match the staffing at the facilities when facilities are reclaiming all of their flows for beneficial reuse. During the interim, additional samples will be set to meet the requirement. |

SSOS |
On October 31, 2019, the Chiquita WRP drained the flow equalization tank causing a surge in the effluent transmission line. This resulted in a spill at the South Coast Water District's Groundwater Reclamation Facility due to a manhole cover not bolted down. Approximately 200 gallons of secondary effluent was contained on site and approximately 300 gallons entered a storm drain that leads to San Juan Creek. |
