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

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 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.
