Funded Projects

Examples of what this program has supported.

FY2025 Funding continues to support projects addressing drinking water contaminants and emerging contaminants in states, territories, and Tribes. Eligible activities include treatment, transmission & distribution, source, storage, creation of new systems, consolidation, household water quality testing, assistance toward technical, managerial, and financial (TMF) capacity, water contamination response efforts, and private wells.

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.

Matching Requirements

The statutory language requires the grant award to have a non-federal cost share/match of no less than 10% of the total costs of the project or activity unless EPA provides a waiver. For FY 2025 funding and awards funded with carryover from prior fiscal years, the cost share match is waived. Matching requirements are to be described in implementation documents. This program does not have a statutory formula. However, EPA allocates funds based on formulas contained in program guidance. Any resources contributed to the project beyond the funds provided by the agency would be considered leveraged resources. Matching requirements are mandatory under annual, non-IIJA appropriations. A non-federal cost share/match is not required under IIJA appropriations. The matching requirement under the SUDC Tribal program has been waived.
