1136728 10/21/2024 Deficient Monitoring Daily total coliform samples are required to be collected from the final effluent sample REC-001 and are used to represent samples collected at REC-002 and M-003A. On 10/21/2024, a temporary power outage occurred, and water was diverted from the aeration basin rather than discharged to the recycled system to respond to the outage, and to access the vault to make repairs by the maintenance staff. During this time, the daily compliance sample was collected during the diversion but was deemed unrepresentative of the final effluent as it was not being sent to the system for tertiary recycled water reuse. A representative sample for that day was not collected; however, based on prior results, there is no indication that water quality changed during this period.
