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.
