# Plain Language Summary: Removing Nitrate and Arsenic in Drinking Water Act

This bill creates a new federal grant program to help communities remove nitrate and arsenic from their drinking water. Nitrate and arsenic are contaminants that can seep into water supplies from agricultural runoff, industrial activities, and natural deposits in the ground. Both are health hazards—nitrate is especially dangerous for infants and young children, while arsenic exposure can cause serious long-term health problems. The bill authorizes $15 million per year starting in 2026 to fund projects that reduce these contaminants.

The grants can go to community water systems, nonprofits with expertise in water treatment, municipalities, and state agencies. Before receiving money, applicants must identify where the contamination is coming from and explain how their project will actually reduce the problem. The program prioritizes disadvantaged communities that have failed to meet federal safety standards for these contaminants in the past three years, as well as projects protecting vulnerable populations like children in schools and daycares. Communities can use the grants to purchase and install treatment technology, with special focus on helping low-income homeowners and renters afford these improvements.

The bill also requires the EPA to review how well the program serves economically disadvantaged and underserved populations to ensure the money is reaching communities that need it most. Only 4 percent of the grant money can be used for administrative costs, meaning at least 96 percent goes directly to actual water treatment projects. This is a relatively modest investment compared to the scale of water contamination problems across the country, but it provides targeted federal support for communities struggling with these specific contaminants.
