Order Conditions |
On 3/1, 2, 6, and 8, the daily average FIL-001 NTU exceeded 2 NTU. This is due to filter backwash cycle ending and when Valves switch back to normal operation a small amount of high NTU leaves the filter. The more backwashes, the more this affects the daily average. |

Deficient Monitoring |
1) Unaware RSW-001and 002 needed fecal coliform and not total. We tested for total. 2) Did not sample for Total nitrogen (as N) or TTHM for Eff-001. Once I realized, we had already switched flow since it was after June 15th. 3) Did not collect a sample during the first week for Ammonia, as I forgot it was no longer once a month. We did collect one the following week while discharging to Eff-001. 40 Influent flow meter was found to have errors in the initial setup and no flow data was collected from 6/15 - 6/30/2023. The average flow (0.450 MGD) for that time period was used in the report. the meter and SCADA programming have been corrected and are now in working order. |
