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 |
