The federal Environmental Protection Agency has implemented a plan to clean up the former Wolff-Alport chemical company Superfund site in Ridgewood. The federal Environmental Protection Agency has implemented a plan to clean up the former Wolff-Alport chemical company Superfund site in Ridgewood. The Superfund site is located at 11-25 to 11-39 Irving Ave. and 15-14 Cooper Ave. The $39.9 million project does not have a clear start or end date and the EPA community coordinator did not return a request by the Queens Tribune for comment by press time.
According to the EPA’s website, the Wolff-Alport location was designated a Superfund site in 2012 after an independent study stated that there are potential health risks due to the radiological contamination to on-site workers and locals who use sidewalks near the site.
The Wolff-Alport Chemical Company worked at the site from the early 1920s until 1954. The thorium waste created from its work was sent into the sewer and possibly buried on the property. It is believed that residual contamination still exists on site and in or around the sewer lines downstream of the facility.
The EPA wrote on its website that the contamination “may present an imminent and substantial endangerment to public health, welfare or the environment.” The EPA will plan a demolition of the site’s buildings and then excavate the soil at the site. The agency will then clean and relocate the soil. Superfund sites are polluted locations that require a long-term response to clean up hazardous-material contaminations. The agency has a national list of sites that are mandated for clean up.
