Description: Level B Mapping delineates a preliminary aquifer protection area, providing an estimate of the land area from which the well draws its water. Level A Mapping delineates the final Aquifer Protection Area, which becomes the regulatory boundary for land use controls designed to protect the well from contamination. As Level A Mapping is completed for each well field and approved by DEEP, it replaces the Level B Mapping. Final Adopted Level A Areas are those where towns have land use regulations for them.
Description: Aquifer Protection Area Adjacent States is a 1:24,000-scale, polygon feature-based layer that includes wellhead protection areas in Connecticut's neighboring states, Massachusetts and Rhode Island. This data is updated as needed.
