Total Maximum Daily Loads (TMDLs)

Total Maximum Daily Loads (TMDLs) are scientific assessments that determine the maximum amount of a pollutant that a body of water can receive and still meet water quality standards. They are essential for protecting aquatic ecosystems and public health. TMDLs consider various pollution sources, including runoff from urban areas and agricultural land, and aim to allocate limits among these sources. By setting these limits, TMDLs help states and communities develop effective strategies to reduce pollution, restore water quality, and ensure safe drinking water and healthy aquatic habitats.
