ADEQ oversees the Water Quality Improvement Grant Program. The grant program allocates money from the US Environmental Protection Agency (EPA) to interested parties for implementation of nonpoint source management and watershed protection. The distribution of grant funds from EPA is provided pursuant to Section 319(h) of the Clean Water Act and administered by the ADEQ Water Quality Division.
ADEQ uses these federal funds to implement on-the-ground water quality improvement projects to control nonpoint source pollution. Nonpoint source pollution is polluted runoff from many different sources and remains the nation's largest source of water quality problems. Pollution occurs when rainfall, snowmelt or irrigation runs over land or through the ground, picks up pollutants and deposits them into rivers, lakes and coastal waters or introduces them into groundwater. Agriculture, forestry, grazing, septic systems, recreational boating, urban runoff, construction, physical changes to stream channels and habitat degradation are potential sources.
