This SWAP zone map identifies nearly 100 known and potential toxic sites within the recharge area of two public water supply wells on Long Island. The identified sites include MTBE (methyl tertiary butyl ether) releases, an Inactive Hazardous Waste Disposal Site, hazardous waste generators and dozens of leaking tanks and spills. Each mapped site can be given a unique identifier number to allow it to be tracked on a going-forward basis.
