Groundwater Rise and Infrastructure Preparedness Act of 2025

HR 4144, the Groundwater Rise and Infrastructure Preparedness Act of 2025, requires the U.S. Geological Survey to create national maps showing future groundwater rise along U.S. coastlines through 2100, including risks like flooding and saltwater intrusion. It mandates identifying high-risk coastal areas and funding a two-phase study with the National Academies to assess impacts on infrastructure (such as roads, sewers, and foundations) and public health (like contaminated water). The bill directs the creation of a public website displaying these maps and requires a final report to Congress within three years. This law directly affects coastal communities, local planners, and emergency managers by providing data to prepare for groundwater-related threats.
