1 CORDELLO AVENUE

The MacKenzie Chemical Works, Inc. (MacKenzie) site, located within a residential/light commercial area of Central Islip, is bounded to the north by the Long Island Rail Road, to the east by private property, to the south by Railroad Avenue, and to the west by Cordello Avenue. The property encompasses approximately 1.4 acres. A two-story block building, which included a former manufacturing building, storage warehouse, and a warehouse/laboratory, was demolished in 2004. Three one-story block buildings were demolished in 2006. The property is abandoned. MacKenzie used the property from 1948 to 1987 for the manufacture of various chemical products, including fuel additives and metal acetylacetonates. The Suffolk County Department of Health Services (SCDHS) and the Suffolk County Fire Department documented poor housekeeping and operational procedures. According to SCDHS, MacKenzie stored 1,2,3-trichloropropane (1,2,3-TCP) in three 10,000-gallon tanks on the property. Other historical waste sources include other storage tanks, leaking drums, waste lagoons, cesspools, and storm-water drywells. Spills, explosions, and fires have occurred at the facility, including a methyl ethyl ketone (MEK) spill in 1977, a nitrous oxide release in 1978, and an MEK spill/fire in 1979. Drinking water wells within four miles of the site serve approximately 141,000 people (three municipal supply wells and one private supply). The nearest municipal supply well is located approximately 3,500 feet southeast of the property. This well has not been affected by site-related contamination. Site Responsibility: This site is being addressed through federal actions.
