Groundwater Resources

Groundwater Resources

About 42% of Ohioans rely on groundwater for their source of water. Knowing where groundwater can be obtained and how it can be managed is important for economic development and mitigating environmental impacts. The Groundwater Resources Group collects data and creates maps that show groundwater availability in Ohio. The group also conducts technical investigations and prepares reports to help all groundwater users understand impacts to the resource. In areas where groundwater withdrawals exceed natural recharge, the group can designate groundwater stress areas with special reporting requirements for groundwater users. Upon request from local governments and boards, the group holds public meetings or hearings to help disseminate groundwater information in conflict areas.
