Where can the federal Safe Drinking Water regulations be found?

The federal Safe Drinking Water regulations are outlined in the Code of Federal Regulations (CFR) under Title 40, specifically in parts 141 and 143, with part 136 providing procedures for effluent guidelines related to water quality. Part 141 establishes the National Primary Drinking Water Regulations, which set enforceable standards for contaminants in drinking water. Part 143 includes secondary standards for drinking water, which are non-enforceable guidelines regarding aesthetic qualities. These regulations are crucial for ensuring safe drinking water quality across the United States. The other titles and parts listed do not pertain to drinking water regulations; they cover different subjects, such as mining (30 CFR) or transportation (50 CFR), thus solidifying the importance of referencing the correct Title and parts in the context of Safe Drinking Water regulations.
