Meas. ID Violated Reg. Meas. Order No. Linked To Enf. 1148311 07/29/2025 Deficient Monitoring Per Sections 3.1 and 4.1 of the MRP, influent and effluent samples shall be analyzed weekly for biochemical oxygen demand (BOD, 5-day at 20° Celsius). The influent and effluent samples collected on July 29 were invalidated due to a laboratory analyst error affecting the analytical QA/QC samples. Therefore, there are no BOD results for influent and effluent the week of July 29. Make-up samples were collected on August 6 and will be reported in the August monthly NPDES monitoring report. To prevent this issue from reoccurring, laboratory staff were reminded to review and follow all method standard operating procedures (SOPs). Violation N eSMR Saugus Water Reclamation Plant 442544 R4-2022-0175 N 1143334 02/19/2025 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. Violation N eSMR Valencia WRP 435564 R4-2022-0174 N 1143333 02/28/2025 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.
