Deficient Monitoring |
During the reporting period, all required BOD analyses were performed by the NCWRP Laboratory (ELAP 2477); however, several results were determined to be invalid due to not meeting method specific quality control criteria. Because these QC failures prevented the generation of valid analytical results, the affected samples are considered non reportable and constitute a failure to monitor. The impacted samples at Monitoring Location RS-001 could not be resampled, as the required 48 hour holding time had elapsed by the time the analyses were completed five days later. |

Deficient Monitoring |
Results for nitrate, nitrite, and calculated total nitrogen at sample locations RSW-001 (bottom and Gauge 96), RSW-002 (surface, middle, bottom), and RSW-003 (surface, middle, bottom) are non-reportable due to a laboratory error in which samples were analyzed beyond the required 48-hour holding time. As a result, valid analytical data were not obtained, and resampling was not completed within the required timeframe, resulting in a missed monthly monitoring requirement. |

Due to issues with the commercial seed product used for the SBWRP Lab¿s Biochemical Oxygen Demand (BOD) analysis, the internal control standard recovery used during the 02/03/26, 02/04/26 and 02/07/26 Effluent composite samples determinations were outside of the method acceptance limits values established in the Current MDLs & Acceptance Criteria (Document #13584) and flagged as non-reportable. Therefore, the SBWRP monthly monitoring is not in compliance with the ¿Minimum Sampling Frequency¿ definition stated in the ORDER NO. R9-2021-0011 for the BOD. Due to the nature of the BOD testing, the samples could not be reanalyzed after the 5-day incubation period when results become known. |

During the reporting period of August 17-23, 2025, the North City Water Reclamation Plant (NCWRP) did not submit pH monitoring data for the reclaimed final effluent. This omission was due to a scheduled facility shutdown originally planned for August 18-22, 2025. At the time, it was anticipated that operations would resume on August 23, allowing for sample collection in accordance with permit requirements. However, the shutdown unexpectedly extended through August 23, preventing sampling and analysis on that date. |

1. Due to a programmed power outage at the PLWTP, the composite effluent and influent samples from the 08/26/25 collection may differ from the composite sample definition stated in the ORDER NO. R9-2017-0007; NPDES NO. CA0107409 Part 2. ¿ Glossary of Common Terms ¿Daily Discharge¿. The 08/26/2025 effluent and influent composite samples were obtained from a combination of at least eight sample aliquots of at least 100 mL at periodic intervals during the time frame from 0001 to 0110 and 1300 to 2359; therefore, the samples not necessarily reflect the plant¿s operating hours over a 24-hour period for the following analyses: Floatable solids, BOD, TDS, TSS_VSS. 2. The BOD internal control standard recovery was outside of the method acceptance limits values stablished in the Current MDLs & Acceptance Criteria (Document #13584). Herby, the result values for the 8/22, 8/23 Effluent and Influent composite samples were flagged as non-reportable. Due to the nature of the BOD testing, the samples could not be reanalyzed after the 5-day incubation period when results become known. 3. Due to contamination during the batch 25219BN35 continuous liquid-liquid extraction; the Hexachlorocyclopentadiene internal control standard recovery and RPD percentages were outside of the method acceptance limits values stablished in the SOP (6144) 625.1 Revision: 11, Section 16. Herby, the result values for the 08/06 Effluent and Influent composite samples processed in were flagged as non-reportable. Additionally, the Bis(2-ethylhexyl) phthalate compound was detected in the Method Blank above the Method Detection Level; the result values for the 08/06 Influent composite sample processed in batch 25219BN35 were flagged as non-reportable. |

Total toxins samples were collected at the required bi-monthly interval from monitoring locations RSW-001, RSW-002, and RSW-003 and submitted to Bend Genetics for analysis in accordance with EPA method 546. The City has historically utilized Bend Genetics as an approved Harmful Algal Bloom (HAB) laboratory, as listed on the SWAMP Cyanobacteria HABs Laboratory List. The City recently became aware that the California Environmental Laboratory Accreditation Program (CA ELAP) now offers certification for EPA 546 which Bend Genetics is in the process of obtaining |

1. During 06/14/25 and 06/15/25 the PLWTPs low flow caused that the effluent autosampler malfunctioned by pulling air from the stinger; herby both composite effluent samples collections from the 06/14/25 and 06/15/25 may differ from the composite sample definition stated in the ORDER NO. R9-2017-0007; NPDES NO. CA0107409 Part 2 Glossary of Common Terms: Daily Discharge. Consequently, the mentioned samples not necessarily reflect the plants operating hours over a 24-hour period for the following analyses: Floatable solids, Biochemical Oxygen Demand, Total Dissolved Solids, Total Suspended Solids and Total Volatile Suspended Solids. 2. The Week One phenols analysis under EPA Method 625.1 did not meet the precision criteria for 2,4-Dimethylphenol. Precision failure was observed in all associated QC samples; therefore, in accordance with QA criteria outlined in SOP ID 6144, Revision 11, Section 16.8, the results for 2,4-Dimethylphenol are considered non-reportable. 3. The monthly Base Neutral analysis under EPA Method 625.1 did not meet precision criteria for Benzidine. Precision failure was due to poor recoveries in all associated QC samples; therefore, in accordance with QA criteria outlined in SOP ID 6144, Revision 11, Section 16.8, the results for Benzidine are considered non-reportable. 4. The monthly Base Neutral analysis under EPA Method 625.1 failed accuracy criteria for Hexachloroethane in all associated QC samples. In accordance with QA criteria outlined in SOP ID 6144, Revision 11, Section 16.3.2, the results for Hexachloroethane are considered non-reportable. |

Due to a sample identification deficiency during the extraction process described in the SOP (1418) O_G_HEM Revision: 7 Section 14.4; the Oil and Grease result values for the 05/23, 05/24 Effluent grab samples were flagged as non-reportable. During the Base Neutral analysis under EPA 625.1, Diethyl phthalate was detected above the method detection limit in the method blank. Per stablished Quality Control criteria in SOP ID 6144 revision 11 section 16.4.2,3 results are non-reportable if the concentration in the blank is greater than one tenth the concentration in sample. Hence, the Diethyl phthalate obtained results for both 05/06 PLWTP¿s effluent and influent composite samples were flagged as non-reportable. |
