1142425 02/15/2025 Deficient Monitoring During the week of 2/15/25 a sample was submitted to the contract laboratory for Total Coliform analysis. The Chain of Custody was correctly filled out requesting Total Coliform analysis, however the contract laboratory incorrectly logged the sample into their custody and assigned the sample for Fecal Coliform instead of Total Coliform. Due to this mistake, there is not a Total Coliform result for that week, and there is only a Fecal Coliform result. Violation N eSMR Ukiah City WWTP 458153 R1-2024-0016 N
1142424 02/08/2025 OEV Total Coliform 7-Day Median limit is 23 MPN/100 mL and reported value was 130 MPN/100 mL at EFF-002. Violation N eSMR Ukiah City WWTP 458153 R1-2024-0016 N

1139588 11/07/2024 Deficient Monitoring The TSS Sample that was collected on 11/07/2024 for location INF-001 was submitted to the contract laboratory for analysis, however the contract laboratory failed to log the sample in for TSS and did not report TSS results. By the time the mistake was caught the contract lab had disposed of the source. No TSS Value is available for the week of 11/07/24 for INF-001. Violation N eSMR Ukiah City WWTP 458153 R1-2024-0016 N
1135065 08/31/2024 Deficient Monitoring August 20th 2024: The Coliform sample collected for monitoring location EFF-002 (Discharge point 002) was analyzed using SM9223 instead of SM9221. The reason for the incorrect analysis was due to an error on the Chain of Custody which requested 9223 instead of 9221. The chain of Custody format has been updated to reduce the chances of recurrence. | September 17th 2024: No Coliform sample was collected for sampling location REC-001 (Discharge point 003) even though discharge had occurred on that day. The sample was not able to be collected while producing Recycled Water due to a communication failure caused by upgrades being performed on the fiber optic communication system.
