prohibition area depicted on Exhibit B is served by the City's public water supply so the prohibition will not create a hardship on area residents or businesses. Water well information is normally gathered through the use of the Source Water Assessment Program(SWAP) database. This database is maintained by the Illinois Environmental Protection Agency(IEPA) and is a compilation of data from the Illinois State Geologic Survey, the Illinois State Water Survey, the Illinois Department of Public Health, and the IEPA. Ground water flow modelsre ared b Bodine estimated that the maximum extent of contaminated p p Y ground water was 462 feet from the site. The water well survey of the area was completed using the IEPA's SWAP database. The database showed one potable water well existing within the proposed ground water ordinance area. A follow-up investigation by Bodine determined that this well is no longer in existence. City water serves the area so future wells will not be needed. The City maintains the location of ground water use restriction areas on its geographic information system(GIS). This information is shared with the Macon County Health Department which is the agency in the County that permits well installation.
