Details: Operator contacted DWS to report that their finished water chlorine monitor (Hach CL17) was recording incorrect data compared to grab sample spot checks. DWS instructed operator that this constitutes failure of chlorine monitoring equipment, and the City should begin collecting grab sample readings every 4 hours until the on-line monitor was operational.

Hach will visit the City on 2/20 to repair or replace the finished water chlorine monitor. The City will inform DWS when their continuous monitoring equipment is operational and they have stopped grab sampling.
