The purpose of this legislation, known as the Water Resources Technical Assistance Review Act of 2025, is to improve the technical assistance provided by the Environmental Protection Agency (EPA) related to clean water infrastructure. It aims to ensure that the assistance offered is effective, well-coordinated, and meets the needs of various communities, especially those that are economically distressed.
