Stage 1 Disinfection By-Products Rule
Beginning January 2004 all community or non transient non community (NTNC) water systems that use continuous chlorination or ozonation during the treatment process must monitor their disinfectant residuals and disinfection by-products.
In order to make this easier, the Department of Health has developed a template for systems that are required to have a Disinfection Byproducts Monitoring Plan. The template is based on an Excel© spreadsheet. To download the template, click below. For specific questions or help contact Kelly Williquette.
