The Hooker (Hyde Park) site is located in Niagara Falls, New York. The 15-acre area was used for the disposal of about 80,000 tons of waste, some of it hazardous material, from 1953 to 1975, resulting in sediment and groundwater contamination with hazardous chemicals. Following cleanup, the site no longer poses a threat to nearby residents or the environment. Construction of the site�s remedy finished in September 2003. Long-term groundwater treatment and monitoring are ongoing.
