Comparison: State vs. Federal

Rules. EPA has granted primacy to DOH to administer the drinking water rules under the federal Safe Drinking Water Act (SDWA). Rhode Island's regulations specify that maximum contaminant levels (MCLs) for inorganic pollutants are the same as the federal regulations under 40 CFR 141, and the state has officially adopted all prevailing federal standards for public drinking water supplies. See the national section DRINKING WATER for more information about the SDWA and MCLs.

Administration and enforcement. DOH's Office of Drinking Water Quality in the Division of Environmental Health has primary responsibility for administering and enforcing the state's drinking water rules and regulations.
