Water Quality Improvement Grant Program

Water Quality Improvement Grant (WQIG) Program allocates money from the United States Environmental Protection Agency (U.S. EPA) to interested parties for implementation of nonpoint source management and watershed protection. The distribution of grant funds from the U.S. EPA is provided to help Arizona citizens achieve the goals of the Clean Water Act with the assistance of ADEQ's Water Quality Division. ADEQ uses these federal funds to implement on-the-ground water quality improvement projects to control nonpoint source pollution. The program strives to fund projects that implement sufficient, economically and scientifically sound management practices that result in quantifiable improvements to surface water quality. 

WQIG program funds projects that address polluted runoff, also known as “non-point source pollution.”  This type of pollution occurs when rainfall, snowmelt or irrigation picks up pollutants and carries them to rivers, lakes or groundwater. Some common pollutants in Arizona are bacteria, nutrients and sediment, with potential sources that include agriculture, forestry, grazing, septic systems, recreation, non-permit regulated urban runoff, construction and physical changes to stream channels. The ultimate goal is to prevent further impacts from such pollution and return Arizonas impaired waters to their designated uses.
