Drinking Water Compliance and Enforcement
National Primary Drinking Water Regulations (NPDWRs or primary standards) are legally enforceable standards that apply to public water systems. Primary standards protect public health by limiting the levels of contaminants in drinking water. These contaminants are divided into:
- Disinfection Byproducts
- Inorganic Chemicals
- Organic Chemicals
The Compliance and Enforcement Program determines whether a PWS is in compliance with all state rules and federal regulations pertaining to the Safe Drinking Water Act. Such determination is based on results of the chemical/contaminant monitoring required for each PWS. If a system is out of compliance, a violation is then issued requiring the PWS to do public notification activities to inform the public that here was a problem, what happened, and what they are doing to fix it.
