The Groundwater Rise and Infrastructure Preparedness Act of 2025 directs the U.S. Geological Survey to map how groundwater levels will rise in coastal areas across the continental United States through 2100 and to study the potential impacts on infrastructure and public health. The bill responds to concerns that rising sea levels—expected to increase 8 to 15 inches by 2050—will cause groundwater to rise in ways that threaten roads, buildings, water systems, and sewage infrastructure, yet no national assessment of these risks currently exists. The legislation authorizes $5 million for fiscal years 2025 and 2026 to develop the groundwater maps and create a public website for community planners and emergency managers, while a separate study commissioned through the National Academies will examine specific impacts to infrastructure and public health over a three-year timeline. The bill affects coastal communities, local governments, water utilities, and federal agencies involved in infrastructure planning and environmental protection, and it requires Congress to receive recommendations on additional resources needed for more accurate future projections.
