WASH Access Data Collection Act of 2024

This bill establishes a federal working group within the EPA to survey U.S. households lacking reliable drinking water or wastewater treatment, focusing on geographic distribution and cost estimates for improvements. It directs the group to use non-personal data (like ZIP codes) to avoid privacy issues and develop a methodology for estimating infrastructure costs. The group will coordinate with agencies like Interior, Agriculture, and Census, and produce a public online index linking federal and state water access data. Every five years, the EPA must report to Congress with detailed findings, including cost estimates broken down by state and congressional district, to inform future water infrastructure planning.
