Deficient Monitoring |
For the NPDES weekly lake requirement for RSW-4(4) there was a deficient monitoring violation for dissolved oxygen. The sample taken on October 1, 2024, was analyzed for dissolved oxygen, but the analyst recorded the incorrect meter display. The result for that day was reported as analyst error for dissolved oxygen. That resulted in one monitoring deficiency for the week of September 29 to October 5. |

Deficient Monitoring |
For the NPDES weekly lake requirement for RSW-4(4) and RSW-W2 (W-2) there were deficient monitoring violations. The samples taken on September 3, 2024, were not analyzed for total kjeldahl nitrogen and organic nitrogen within their holding time. The samples were put away prematurely before conducting all the required analysis, resulting in the samples being past holding time. Consequently, no results were reported for total kjeldahl nitrogen, organic nitrogen, and total nitrogen for the week of September 1 to September 7 resulting in 1 weekly monitoring deficiencies. |

Deficient Monitoring |
The flow meter discharging into Balboa Lake stopped working on July 26, 2023. Effluent flow is a continuous monitoring requirement reported on a daily basis for the daily average flow and daily maximum flow. The daily average effluent flows being reported for effluent discharge starting on July 25, 2023 are approximate values. The flow to Balboa Lake is being estimated based on pump capacity. Until the meter is replaced, the reported daily average flow for the effluent will continue to be an approximate value. Due to the Balboa Lake meter not working, the daily maximum for the effluent flow cannot be determined, these have been reported as an instrument failure (IF) since July 25, 2023. |
