National Secondary Drinking Water Regulations (NSDWRs or secondary standards) are The EPA has established the National Primary Drinking Water Standards (NPDWRS) as a mandatory quality standard for the quality of our drinking water. These new regulations are legally enforceable, and they set Maximum Contaminant Levels (MCL’s) to ensure that the public is protected from using water that may be a health hazard.
