Site Description

The MacKenzie Chemical Works, Inc. site is located within a residential/light commercial area of Central Islip. The 1.4-acre property houses three one story block buildings. A two story block building, which included a former manufacturing building, storage warehouse, and a warehouse/laboratory, was demolished in August 2004. The property is abandoned.

The property was used from 1948 to 1987 for the manufacture of various chemical products, including fuel additives and metal acetylacetonates. According to the Suffolk County Department of Health Services, MacKenzie stored 1, 2, 3-trichloropropane 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.

Current Site Status and Cleanup Actions to Date

  • EPA selected a remedy for the site in a Record of Decision (ROD), or cleanup plan, in March 2003. The ROD called for thermally-enhanced in-situ soil vapor extraction (SVE) (PDF) (80 K, 2 pp) for soils contaminated with volatile organic compounds, limited excavation and off-site disposal for soils contaminated with semi-volatile organic compounds, demolition of the former laboratory building, and treatment of the groundwater using in-situ air sparging with ozone injection.
  • In March 2004, work began on constructing pilot-scale treatment systems for the soil and groundwater remedies. This effort culminated in completion of the construction of the SVE system (the soil remedy) and the ozone injection system (the groundwater remedy) in May 2004. The systems started up in June 2004 and have run continuously since that time. Based on an evaluation of the data generated relative to the SVE system, it appears at this time that the system is successful in removing contaminants from subsurface soils. An evaluation of data generated relative to the ozone injection system is underway.
  • In August 2004, EPA demolished the former laboratory building.

Current Funding Status

  • Thus far, EPA has provided $500,000 (FY-03) to perform pilot-scale treatability studies related to both the SVE and ozone injection remedies and $1.2 million (FY-04) to carry out the remaining cleanup work at the site.
