In partnership with the U.S. Environmental Protection Agency and Purdue University, the Local Government Environmental Assistance Network (LGEAN) recently launched an online tool to help local government planners measure the water quality impacts of land use changes. Specifically, local governments provide information about their location, the proposed land use change, and the area's soil type. Based on community-specific climate data, the Long-Term Hydrologic Impact Assessment (L-THIA) model estimates changes in recharge, runoff, and non-point source pollution resulting from proposed development.
