Water Quality Restoration Planning in Rhode Island
TMDL icon
Total Maximum Daily Load (TMDL) Program

DEM's Office of Water Resources develops water quality restoration plans, with public input, to restore and maintain water quality for impaired/polluted waters. Waters are impaired if they do not meet state water quality criteria. These plans, required by the federal Clean Water Act, are called Total Maximum Daily Loads or TMDLs. TMDL is a term that represents the total pollutant that a waterbody can assimilate and still meet water quality standards.
