What Does NPDWR Stand For?

NPDWR stands for National Primary Drinking Water Regulations

NPDWR, or National Primary Drinking Water Regulations, refers to the set of federal standards established by the United States Environmental Protection Agency (EPA) to ensure the quality and safety of public drinking water supplies.
