Protect clean air, clean water, and public health and conserve working farms, forests, and natural lands. It is therefore important to maintain a suitable amount of free chlorine throughout the entire distribution system to react with any contaminants that may be introduced into the distribution system through breaks, backflow, treatment breakdown or other avenues. By meeting the goal, it not only provides for extra public health protection, but also helps with evaluating increasing trends that may indicate either treatment or distribution system issues that may not have otherwise been detected.
