What chlorine level condition warrants a boil water notification?

A boil water notification is typically warranted when there are low chlorine levels in the water supply. Chlorine is a critical disinfectant used to kill harmful bacteria and pathogens in drinking water. If the chlorine levels drop below the acceptable minimum threshold, it indicates that there is insufficient disinfection occurring, which raises concerns about the safety of the water for consumption.

Consumers are advised to boil water to eliminate potential presence of harmful microorganisms until the water system can ensure that chlorine levels are restored to safe and effective concentrations. This precaution helps protect public health during periods of compromised water quality.
