Benefits of using a disinfectant residual
Given the age and vulnerability of some US water distribution systems, use of a disinfectant residual as an added safeguard makes sense.
Water distribution systems in the United States routinely carry chlorine residuals < 0.05 mg/L and invariably carry residuals > 0.1 mg/L. This article outlines some of the benefits of using chlorine as a disinfectant residual and considers system characteristics (e.g., system age and vulnerability) that support this application. Benefits accruing to maintenance of a chlorine residual include protecting against modest degrees of intrusion of contaminants, serving as a sentinel for the presence of such contamination, and reducing the potential for growth of heterotrophic organisms.
