| Details: | SUMMARY: Elevated Turbidity Levels DETAILS: Dave Elder called at 3:15 pm to report that they have had elevated turbidity all day (due to heavy rains and higher tides) ranging between 1 and 1.9 NTU. They completed additional sampling in the distribution system and recorded a chlorine residual of 0.31 to 0.41 mg/l, with an entry point chlorine residual of 0.73 mg/l at the time of highest turbidity (1.9 NTU). ACTION NEEDED: Continue to monitor chlorine residuals and turbidity levels and keep DWP informed of significant changes in either chlorine residuals or turbidity. | ||
