Village of Ada - First fully endorsed wellhead protection plan in northwest Ohio and further implementation of the plan

Pioneering source water protection planning – essentially defining how source water protection was to be done 1990-1998 in Northwest Ohio. Work included delineation conducted with MODFLOW-MODPATH, using onsite data (aquifer testing, fracture analysis), and planning protection practices. The delineation submitted was one of the first in northwestern Ohio and was a test-bed for acceptance of MODFLOW-MODPATH delineation in the carbonate aquifer (building on existing Ohio State University experience). The PPSI was relatively detailed due to the long industrial history and numerous glacial layer perforations in the vicinity of the wellfield. The MEP was the first endorsed in northwest Ohio, and was endorsed with little request for modification by the Ohio EPA.
