Water Quality Restoration Studies Total Maximum Daily Load (TMDL) Program DEM's Office of Water Resources develops water quality restoration studies, 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 studies, 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. Learn more about RI’s water quality restoration efforts. Rhode Island’s TMDL studies identify water quality goals, necessary pollutant reductions to achieve these goals, the sources of pollution found contributing to the pollution problems, and the necessary pollution control actions to achieve the required reductions and restore water quality. To learn more about which waterbodies have TMDLs completed and to view TMDL documents, visit TMDL and Water Quality Restoration Study Documents.
