Deficient Monitoring |
Per Section 4.1 of the MRP, effluent samples shall be analyzed monthly for dissolved oxygen. An effluent sample for dissolved oxygen was inadvertently not collected in March due to a laboratory oversight. The Los Coyotes WRP was operating normally in March and effluent dissolved oxygen levels are expected to have been within normal ranges. To prevent this issue from re-occurring, staff have been instructed to more proactively monitor sample collection schedules to ensure that all required samples are collected. |

Deficient Monitoring |
Per Section 4.1 of the MRP, continuous monitoring of total residual chlorine shall serve as a trigger for increased grab sampling for total residual chlorine excursions of up to 0.3 mg/L lasting more than 15 minutes or excursions between 0.1 to 0.3 mg/L lasting longer than 15 minutes. At 11:50 a.m. on February 19, the Valencia WRP temporarily lost power while testing the emergency generators. The emergency generators turned on; however, there was a slight delay, resulting in temporary power loss at the Valencia WRP. As a result, the UV disinfection system was shut down, and all effluent flow was routed to the chlorine contact tanks for disinfection. During this transition, the metered final effluent total residual chlorine exceeded 0.3 mg/L for approximately 8 minutes and remained between 0.1 and 0.3 mg/L for approximately 16 minutes, triggering collection of an additional grab sample. At 12:25 p.m., a grab sample was collected, and chlorine was not detected; however, collection and analysis did not follow analytical method protocols. As a result, the non-detect result was not reportable. Despite this, sodium bisulfite, the dechlorination chemical, was dosed more than the stoichiometric amount needed to fully dechlorinate the effluent; therefore, the effluent was fully dechlorinated. To prevent reoccurrence, the Sanitation District will implement procedures to ensure all additional grab samples collected for total residual chlorine analysis follow analytical method protocols. |

Deficient Monitoring |
Per Section 4.1 of the MRP, effluent samples shall be analyzed monthly for dissolved oxygen (DO). An effluent sample was not collected in February because of a laboratory analyst error. A make-up sample was collected on March 3, and the DO result will be included in the March report. To prevent this issue from reoccurring, analysts were reminded to carefully check that all required monitoring samples are collected within the required timeframes. |

Surface Water |
Per Section 5.1.16 of the WDR, the discharge shall not result in visible floating particulates, foams, or oil and grease in the receiving waters. On February 20 at 9:45 a.m., Sanitation Districts sampling personnel observed foam in the San Gabriel River downstream of Discharge Point 001B and traveling to receiving water station RSW-007 (R-13). Operations staff confirmed that the SJCE and SJCW WRPs were operating normally during this time and no changes to the treatment process or foaming had occurred at the plants. However, as a precautionary measure, the defoamant dose was increased at both WRPs the same day. The sampling crew returned to receiving water station RSW-007 (R-13) the following day on February 21 at 10:52 a.m. and observed less foam; by 2:14 p.m., the foam was no longer present. The Sanitation Districts will continue to monitor water quality in the effluent and receiving waters, and the San Jose Creek WRP Operations staff will continue their normal procedures to increase the defoamant dose if foam is observed. |

Per Section 4.1 of the MRP, effluent samples shall be analyzed monthly for aldrin and dieldrin. The effluent sample collected on November 28 was invalidated because it was not delivered to the laboratory within 72 hours for pH adjustment, as required by the analytical method for these compounds. Therefore, there are no reportable aldrin and dieldrin effluent results for the month of November. A make-up sample was collected on December 16 and will be included in the December monthly report. To prevent this issue from reoccurring, a 3-day sample hold time will be implemented to ensure that laboratory pH measurements and adjustments are completed within the 72-hour method requirement. |

On August 19, a sample for oil and grease analysis was collected; however, an analyst did not follow proper extraction procedure and the sample was lost (the solvent gas valves in the extraction instrument were inadvertently not opened). To prevent the issue from reoccurring, analysts have been reminded to check the valves and verify solvent and gas levels prior to sample extraction. A make-up sample was collected on September 6, 2024, and will be included in the September NPDES report. |
