Public asked whether Flagstaff water nitrate and disinfectant are natural; staff says nitrates are naturally occurring and disinfectant is chlorine
Summary
A public commenter asked whether nitrates and an observed disinfectant in Flagstaff water are naturally occurring; Water Services Director Lee responded that nitrates would be naturally occurring and that the system uses chlorine (forms hypochlorous acid) as the disinfectant.
At the start of the open-call portion, Ryan Saraf asked whether nitrate levels and a water disinfectant he saw in published water reports were naturally occurring. Chair Doba deferred technical detail to Water Services Director Lee.
Lee answered that nitrates noted in reports would be naturally occurring and that the only disinfectant added by the utility is chlorine, which forms hypochlorous acid to prevent waterborne illness. Staff offered to provide follow-up information by email or through the water quality address for more detailed or technical questions. A second speaker, Sophia Murray, had filed a written request; staff deferred her topic to Lee for follow-up.
