The 1,063-acre Newport Naval Education/Training Center (NETC) site has been used by the Navy as a refueling depot since 1900. An 11-acre portion of the site along the shore of Narragansett Bay, known as McAllister Point Landfill, accepted wastes consisting primarily of domestic refuse, acids, solvents, paint, waste oil, and oil contaminated with polychlorinated biphenyls (PCBs) from 1955 to the mid-1970s. Five tank farms are located in the Melville area; one is located in Midway. Sludge from nearby tank farms was dumped on the ground or burned in chambers. Other contaminated areas on site, such as the Melville North Landfill, are classified as Formerly Used Defense sites and are being addressed separately. Surface water and groundwater flow toward the bay, which is used for boating and fishing. One tank farm is located 300 feet from a coastal wetland. Other areas of concern include Old Fire Fighting Training Area/Site 09, Tank Farm Four/Site 12, Tank Farm Five/Site 13, Gould Island, and Derecktor Shipyard. An estimated 4,800 people obtain drinking water and 220 acres of land are irrigated from private wells located within 3 miles of the site. Approximately 10,000 people live within 3 miles of the site.
