Program objective
The objective is to assist communities that are small or disadvantaged to comply with the Safe Water Drinking Act (SDWA). Funding is awarded to states, territories, and Tribes/Tribal water systems, for projects/activities that are necessary for public water systems to comply with national drinking water standards established by SDWA. Funding will continue to support projects and activities that benefit underserved communities. Underserved communities have an inadequate system for obtaining drinking water and include those communities that do not have household drinking water or wastewater services, or are served by a public water system that violates or exceeds a requirement of a national primary drinking water regulation issued under SDWA section 1412, including a maximum contaminant level; a treatment technique; or an action level. Additionally, funds may be used to provide support towards testing, reduction, and remediation of emerging contaminants. The funding priority will continue to be projects and activities that benefit small or disadvantaged communities. Small communities include those will populations less than 10,000 individuals. Disadvantaged communities are those that meet affordability criteria established by the state in which the project takes place. For FY25 funding, projects supporting private wells are also considered eligible activities.
