1131497 07/22/2024 ATOX Acute Toxicity 3-Sample Median limit is 90 % survival and reported value was 85 % survival at EFF-001. Violation N eSMR Delta Diablo WWTP 435913 R2-2019-0035 N
1119668 07/07/2023 Deficient Reporting The analysis results for BOD samples (INF-001 and EFF-001) collected on July 7th are invalid because the tests failed the quality assurance and quality control (QA/QC) protocols for the test. Consequently, the District does not have the two valid BOD sample results required for the first week of July. The District reanalyzed the sample collected July 7th on July 13th. However, this test is beyond the acceptable hold time for BOD sampling. As such, these sample results are qualified in CIWQS as analyzed after the holding time expired. Violation N eSMR Delta Diablo WWTP 435913 R2-2019-0035 N
1115063 02/01/2023 Deficient Monitoring The analysis results for the BOD samples collected on February 1st and 2nd are invalid because the tests failed the quality assurance and quality control (QA/QC) protocols for the test. Consequently, the District does not have the two BOD sample results required for the first week of February. The QA/QC failed because the Laboratory Control Samples (LCS) for the BOD samples collected on those two days were prepared with the incorrect standard. The sample results for the Ammonia samples collected on February 8th and 9th were analyzed outside of the normal hold times. Violation N eSMR Delta Diablo WWTP 435913 R2-2019-0035 N
1114026 01/04/2023 Deficient Monitoring The analysis results for BOD samples collected on January 4 and 6 were invalid because the tests failed the quality assurance and quality control (QA/QC) protocols for the test. Consequently, the District does not have the two BOD sample results required for the week of January 1st. District staff investigated the cause of the failed analysis and determined the QA/QC failure was related to the heavy storms that occurred during early January. The significant storms over-diluted the primary effluent used to seed the BOD. Violation N eSMR Delta Diablo WWTP 435913 R2-2019-0035 N
1112692 12/31/2022 Unauthorized Discharge On Saturday, December 31, 2022, the District experienced extraordinarily high influent flows throughout its satellite collection systems and conveyance system as a result of the atmospheric river that hit the Bay Area. There was an overflow in the headworks area of the Delta Diablo Wastewater Treatment Plant (WWTP) located at 2500 Pittsburg Antioch Hwy in Antioch, CA. A portion of the overflow, consisting of wastewater that had been screened and underwent grit removal, may have reached a stormwater drainage canal to the east of the WWTP. Most of the overflow was contained onsite and sent through the WWTP for full treatment. The overflow started at 1715 and ended at 1830 (75 minutes) at the grit chamber. The total overflow volume is estimated at 84,375 gallons and the flow travelled to the west, north, and east of the overflow point and was mostly contained on the WWTP site where it will be returned through the system for full treatment (80,625 gallons). The portion of the overflow that may have reached receiving waters is estimated to be 3,750 gallons (50 gallons per minute for 75 minutes). The involved waterway was the Los Medanos Wasteway, a drainage canal running north to south along the east side of the WWTP. CalOES was notified of the unauthorized discharge. No receiving water sampling was conducted as river conditions were deemed unsafe for staff during the storm event. Observations of the receiving waters could not be made due to the discharge being diluted by inflow and infiltration and due to the saturation of the area due to the rainfall.
