1131232 07/03/2024 DMON On July 12, 2024, the City was notified by the contract laboratory, Eurofins, that the CalScience sub-laboratory had been experiencing contamination issues with one of their BOD instruments and have had failing Unseeded Control Blank and Laboratory Control Samples. They have been working on mitigating the issue by ordering new parts to replace instrument tubing and to conduct decontamination cleanups. Samples impacted include WRF No. 3 weekly influent and effluent BOD samples collected on July 3rd. Impacted samples with results that did not align with historical values were reanalyzed past hold time for result confirmation. A corrective action report was requested for these samples and is included in this report. The backup instrument was prepared for the next batches and troubleshooting the contamination began. The plan was to replace all tubing and carboys. Most were available in stock and some had to be ordered. The bottle cap cleaning regimen was changed to using bleach and oven drying. Once the ordered tubing had been received and all tubing was replaced, a blank study was performed. The study took the entire five days. The results were still showing detections in the USB. There was a small length of tubing that was used to extend the seed tube dispenser that had been overlooked. This tube was removed and was not replaced. Another blank study was performed. This time the blank was clean. Corrective Action: 1. Bottle cap cleaning regimen was changed to using bleach and oven drying. 2. Replacement of tubing on a schedule. Contamination of the BOD instrument system is a common issue in this analysis. The 5-day closed system leaves the outcome uncertain. We make best efforts to sustain a clean system with the unclean samples we expose it to. An additional blank study was begun on 8/19/2024 as an additional quality control measure. We expect that study to return clean and the instrument can be put back on line. Violation U eSMR
1122969 11/25/2023 DMON On November 27, 2023, the City of Corona was notified by the laboratory, Eurofins Drinking Water Testing (Eurofins), that all November 25th samples collected by the Eurofins field technician were not preserved on ice and are not valid for compliance. This includes the WRF No. 3 effluent total coliform sample. The City requested a Corrective Action Report from the lab which will be included in the December monthly report. Violation U eSMR
1108843 08/02/2022 DMON Ammonia Nitrogen was collected on 8/2/22 in an improperly preserved container. The City was not notified and the lab missed resampling for this. Lab confirmed volume from TSS from 8/31 to run ammonia nitrogen, but data would not be valid for compliance. The City has requested a Corrective Action Report from the lab for this sample. Violation U eSMR
1103488 03/29/2022 Order Conditions WRF No. 3 experienced low chlorine conditions. No discharge from CCB during low conditions, wasted to sewer. Violation U eSMR
