 The county has been determined as a Tier I county for economic development.The state claimed that the Warren County site was the best available site; however, the site selection process was not based on scientific criteria — soil permeability properties or the distance to groundwater — but on other, less tangible criteria, including the demographics of the county.EPA and state officials claimed they could compensate for improper soil qualities and the close proximity to groundwater with the engineering design of their "state-of-the-art", "dry-tomb", zero-percent discharge landfill.
