A monthly oil and grease sample was missed at M-001E for the reporting period. This was due to an error in sample preparation and an accidental oversight in the master schedule which cause the sample to be missed. All other samples for the month were collected as planned. Since no operational changes occurred during this period, no differences in results are expected compared to previous months |
IRWD is currently implementing a new LIMS software with features for tracking and scheduling samples, which will enhance the identification and resolution of sampling gaps. This system is expected to go live in late 2025. |

The 24-hour composite samples for Weekly Turbidity and TDS samples at M-00E(Irvine Desalter Project Potable WT System) were not monitored for the week of 7/30 to 8/5. The composite sample was scheduled for 7/31, but due to the composite sampler malfunctioning, a grab sample was collected and analyzed in lieu of a 24-hr composite. Due to lack of communication, the sampling schedule was not adjusted to recollect the weekly Turbidity and TDS 24-hour composite samples. |
As a corrective action, sampling staff will receive additional training to ensure composite samples are rescheduled to meet the weekly 24-hour composite requirement of the permit. |

IRWD Regulatory Compliance Monitoring staff did not collect the Oil & Grease sample for M-001E, PTP Brine location for the month of October. The South Orange County Wastewater Authority (SOCWA) Region 9 NPDES Permit requires a monthly sample for Oil and Grease at this sample location and the monitoring was scheduled to occur on October 6, 2022. The Regulatory Compliance Monitoring group was short staffed that week and were unable to collect the monthly sample and needed to reschedule for a later date. There was a gap in communication and follow up to ensure that the sample collection was rescheduled, resulting in the missed sample. |
As corrective actions, IRWD Regulatory Compliance Monitoring staff have implemented a thorough review of October sampling events to ensure no other SOCWA R9 samples were missed. Additionally, Regulatory Compliance staff have implemented additional measures of coverage for the schedule tracking sheets and defined verbal and written communication protocols for samples that are needed to be rescheduled.

While re-reviewing the submitted data this morning for the ACOO, we discovered that there was a missed sample weekly event at M-001B for dissolved oxygen. All other entities were sampling for D.O. during that week so please advise if we will need to withdraw the submitted CIWQS report, and add a deficiency for the weekly monitoring. As a reminder, we are sampling at each plant because the monitoring station at the outfall has been down. We have the monitoring station scheduled in our capital program and should have a unified sampling location soon. - Amber Baylor |

On June 10, 2021, the sewage sludge force main between the South Orange County Wastewater Authority¿s (SOCWA¿s) Coastal Treatment Plan (CTP) and the Regional Treatment Plant experienced a pipeline failure resulting in a spill of non-chlorinated sewage sludge within the Aliso and Woods Canyons Wilderness Park (AWCWP) (Figure 1). The spill was situated along a dirt maintenance road off Alicia Parkway on the east side of Aliso Creek; the road is intended to provide the dual purpose of providing access to existing sewer and wastewater infrastructure as well as providing trail use to those who recreate in the AWCWP (Figure 2). The pipeline leak was repaired, and the spill was contained on the same day. A total spill volume of approximately 1,920 gallons of sewage sludge was released, cleaned up, and disposed of properly offsite. |
