| Details: | Saturday 6:10 pm Jake is hopeful. They are jar-testing. CFE is now 2.1 NTU. All filter NTU is dropping. Collected 4 coliform samples, sent to lab. Chlorine residuals in town range 0.5 ppm to 0.85 ppm. WT3 and WT4 operators are on staff 24/7 to try to lower turbidity. Their SCADA system only reads to 1 NTU so needs to visually check actual turbidities. Sunday 8 am CFE is 0.393 NTU. IFE’s: 0.84, 0.29, 1.03, and one in backwash. Chlorine is at 1.29 ppm. Sunday 1:20 IFE’s improving slightly. CFE 0.236 NTU. They are increasing flow rates through filters. Sunday 5 pm All coliform samples are absent for TC. |
