Region 2 Superfund

Five Year Review [PDF 14 KB, 1 pg]

EPA added the Sealand Restoration Inc. Superfund site in Lisbon, New York to the National Priorities List on August 30, 1990 because contaminants were found in onsite soils and ground water.  The 210-acre site, located in St. Lawrence County, operated as a disposal facility for hazardous materials such as petroleum wastes. Ground water was contaminated with heavy metals and volatile organic compounds (VOCs), which are potentially harmful contaminants that can evaporate easily into the air. Approximately 1,000 people live within three miles of the site, but sampling indicated that contaminated ground water was not impacting residential wells. Soils were found to contain low levels of PCBs, pesticides, heavy metals and phenols, which are chemicals used to make plastics and detergents. Surface water also was found to be contaminated with metals.

Wastes on the surface of the site, contaminated soils, buried drums and waste water were removed from the disposal area. The area also was filled with clean soil and covered with a multilayered cap. Ground water was pumped to restore it to federal and state standards. EPA issued Five-Year Review reports in 1998, 2003, and 2008 that concluded that the cleanup has been protective of human health and the environment. Under current conditions at this site, potential or actual human exposures are under control.
