Ingham County Groundwater Survey

The tri-county region relies on groundwater for the vast majority of our drinking water resources, whether it’s delivered to consumers’ homes through public water suppliers or individual private wells. Relying on this underground and out-of-sight resource requires an innovative approach to properly manage its consumption and ensure its safety for all.


To help better understand our groundwater system, the Ingham County Health Department launched a survey of the Saginaw Formation, our regional aquifer, for the entire county in the early 1980s. This original survey sampled over 300 wells and analyzed the groundwater quality of all 16 townships. Published as the Report on the Aquifer of Ingham County, the collected well data was used to develop more effective groundwater management programs.


In 2015, the Ingham County Groundwater Survey project began as a follow-up to the original 1980s report. The goal of the survey was to re-sample as many of the same wells as possible to identify any changes in the composition of the county’s groundwater. This also provided an excellent opportunity to educate well owners on well protection, determine future strategies for groundwater protection, and provide a framework to expand the project into Eaton and Clinton Counties.


Thanks to countless hours of work, support from the Groundwater Management Board, and a wide range of partnerships across the county, the project has completed well sampling in all 16 townships and shared the results with each community to help educate public officials on effectively managing our groundwater.

Clinton County Groundwater Surveys

In partnership with the Lansing Board of Water and Light, the Groundwater Management Board is pleased to report the Groundwater Survey has expanded into neighboring Clinton County. Well sampling for this project was completed in 2021 with wells located in DeWitt Charter and Bath Charter Townships. View the final report of these townships in the gallery below.
