Comparison: State vs. Federal

Rules. Louisiana received primacy in 1977 from EPA for Safe Drinking Water Act (SDWA) enforcement authority. Under state drinking water regulations, new and existing systems, as well as DWRLF applicants, must meet specific requirements. See the national section DRINKING WATER for more information about the SDWA.

Administration and enforcement. DHH's Office of Public Health is responsible for administering the SDWA requirements in Louisiana. Several other state regulatory programs have an impact on drinking water, including pollution control programs of DEQ, the Office of Conservation in the DNR, and the Office of Public Works in the LDTD.
