Ground Water & Hydrology

Spencerville, Ohio – Source water delineation and testing and modeling for strategic water planning

Spencerville has a high-capacity carbonate-aquifer wellfield in a politically and technically sensitive aquifer setting (a designated sole-source aquifer) in which both public water suppliers and private-well owners maintain marginal ground water supplies. Work included analysis of studies by other consultants in the area and technical liaison with the state and neighboring communities, WHPA delineation using MODFLOW, based on detailed local data collection, well capacity testing and regional aquifer-scale testing to update the numerical model of the wellfield.
