The Wellhead Protection Viewer is an interactive online mapping application that provides a variety of data – including well locations, time of travel areas, brownfields, potential contamination source locations, and more – so communities and organizations can be better informed when making development decisions that may affect our groundwater throughout Clinton, Eaton, and Ingham counties. This tool is a useful resource for planners looking to identify locations at greatest risk for groundwater contamination when preparing site plan reviews, emergency response plans, and risk and resilience assessments, all of which help protect our drinking water at its source!

Since its creation in 1999, the Viewer has undergone numerous updates to provide this data and continues to be made available for public use thanks to a combined effort of grant funding, cost sharing, and regional collaboration between Tri-County and member communities of the Groundwater Management Board (GMB).
