Wellfield Protection Areas
The Hamilton to New Baltimore Ground Water Consortium defines well field
protection areas as “surface and subsurface areas which will contribute
water to a well or well field over a specific time period (generally five years).”
The well field protection designation is intended to protect the Region’s valuable
drinking water at the site where it is withdrawn from the aquifer.

The Ohio Environmental Protection Agency’s (OEPA) Wellhead Protection
Program specifies that two well field protection areas, inner management
zone and outer management zone, be defined around each public water
supply site or well field to establish different management strategies. The
inner management zone is the protection area immediately surrounding a
well field while the outer zone is beyond the inner management zone.

Similar to the U.S. Environmental Protection Agency’s (USEPA) classification,
Going Places classified the Region into three areas: inner ring well field protection
area; outer ring well field protection area; and no protection area.
