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.
