New York City may soon notch a third site on the EPA’s Superfund list of the nation’s most hazardous waste sites. The candidate is the Wolff-Alport Chemical Company site, a defunct business that processed and sold minerals containing thorium from the 1920s to 1954 in Ridgewood, Queens. Wolff-Alport imported monazite sands, rich in thorium, from central Africa. The site is currently radioactively contaminated, although the risks from this residual radioactive contamination do not represent a health concern in the short-term, it could pose a health risk under certain long-term exposure scenarios. Additional investigation and remedial work is needed, so the EPA is proposing that Wolff-Alport be added to the National Priorities List of Superfund sites.
A lot of work has already been done at the site. The EPA installed protective shielding on portions of the site that will prevent nearby residents, employees and customers of area businesses from being exposed to elevated gamma radiation from below the surface. The shielding material included concrete, lead and steel, depending on the area.
Reporters often ask me to compare the cleanup work at the two other NYC Superfund sites, the Gowanus Canal and Newtown Creek. The Gowanus Canal was built in the 19th century to ease the transport of goods and services. After its completion in the 1860s, the canal became a busy industrial waterway including manufactured gas plants, coal yards, concrete-mixing facilities, tanneries, chemical plants, and oil refineries. Sadly, it also became a giant receptacle for untreated industrial waste, raw sewage and runoff. EPA’s $506 million Gowanus cleanup will require the removal of contaminated sediment and the capping of dredged areas. The plan also includes controls to reduce sewage overflows and other land-based sources of pollution from ruining the cleanup.
Newtown Creek and the Gowanus Canal share a legacy of urban and industrial pollution as major arteries in the City’s transportation system. In the late 1800s and throughout most of the 1900s, Newtown was replete with sprawling oil refineries, petrochemical plants, factories, plants, sugar refineries, canneries, sawmills, and lumber and coal yards. Similarly, the creek is negatively impacted by discharges from combined sewer overflows and sewer treatment plants.
Where the Superfund sites differ significantly is in the status, or better said, where they are situated on the Superfund Roadmap. In 2013, the EPA issued a Record of Decision for the Gowanus cleanup. This milestone document explains what cleanup alternatives the Agency has decided are the best choice to clean up a Superfund site. In the case of the Gowanus, the decision document came after the EPA held a 120-day period to receive public comments and hosted two formal public meetings. Prior to the Record of Decision, the Agency evaluated more than 1,800 e-mails, letters, postcards and petitions about the cleanup. Conversely, Newtown Creek is a few years away from a Record of Decision. Currently, the creek is undergoing assiduous sampling and study as part of the EPA’s Remedial Investigation and Feasibility Study. During this phase, the EPA will determine the nature and extent of contamination. This scientific work is expected to be completed in 2018 and would be followed by a proposed cleanup plan for the public’s consideration.
Another NYC site, the Radium Chemical Company site at 60-06 27th Avenue, Queens was on the Superfund list from 1989 to 1995 when the EPA led a successful cleanup of a radioactively-contaminated plant that no longer poses a threat to public health or the environment. It has since been delisted.
Naysayers claim that placing these sites on the Superfund list creates a stigma and is “bad for business.” Protecting human health and the environment is EPA’s first concern, but there is ample evidence to suggest that a Superfund cleanup can help communities and be a boon to local commerce by creating economic opportunity and using innovative technologies to mitigate contamination in a cost-effective manner. A cleanup also gives rise to redevelopment of an area that was once blighted, thus returning a contaminated property to the community and the tax rolls.
