Queens, New York Brownfield Site Goes Green

BLOOMFIELD, CT. February 21, 2012. VeruTEK Technologies, Inc. (VTKT), a provider of patented Green Chemistry technologies for environmental remediation and enhanced oil recovery, announced today a Certificate of Completion (COC) has been issued by the New York State Department of Environmental Conservation (NYSDEC) for the successful cleanup of a New York City brownfield.
The site, located along the East River in Hunters Point, Queens, NY will be redeveloped for a new branch of the Queens Public Library and a New York State Parks ranger station. VeruTEK successfully implemented its patented Surfactant-enhanced In Situ Chemical Oxidation (S-ISCO) technology at this former industrial site to remediate contamination from coal tar repurposed from Manufactured Gas Plants (MGPs) for use in the production of roofing products.
This S-ISCO remediation marks the first time a Green Chemistry solution of this kind has been used to remediate MGP-related contamination in New York City and sets a precedent for the use of innovative technologies to achieve a COC within the state’s Brownfield Cleanup Program.
S-ISCO provided a low-impact solution that benefits the health and safety of the community and environment. Specifically VeruTEK’s innovative treatment:
Destroyed contamination in place, avoiding digging and hauling thousands of truck-loads of contaminated soil through the community while preserving the stability of the subsurface and high-rise buildings on adjacent parcels;
Prevented surrounding businesses and residents from being exposed to dust and emissions related to large scale excavation, and also reduced soil gas contamination;
Took place during a short time frame (five months), without disturbing the community; and
Provided a permanent solution to site contamination, preparing the site for safe and productive reuse.
Arana Hankin, President of Queens West Development Corporation (QWDC), the New York State public authority responsible for the development of the Queens West project, said, “Issuance of a Certificate of Completion for this brownfield site is an exciting milestone in the redevelopment of Queens waterfront property. We look forward to beginning the next phase of redevelopment, construction by the City of New York of a state-of-the art public library on the site, which was cleaned up with virtually no disruption to the community.”
At this urban site, VeruTEK conducted S-ISCO injections to treat more than 50,000 pounds of coal tar contamination in the soil by destroying in-situ (in place underground) over 90% of the combined polycyclic aromatic hydrocarbons (PAHs) and BTEX compounds, including 95% of the naphthalene. VeruTEK’s novel S-ISCO technology combines patented plant-based surfactant and co-solvent mixtures (VeruSOL) with free-radical oxidant systems to safely release (desorb) and destroy recalcitrant contaminants from the soil. VeruTEK’s S-ISCO technology destroyed the primary source of contamination, yielding a permanent solution for the site.
VeruTEK’s S-ISCO technology was selected by Fleming Lee Shue, a New York City based environmental management and consulting company which was commissioned to design and manage the cleanup effort by QWDC and a leading national developer and manager of high quality apartment communities. The S-ISCO treatment was augmented by Wavefront Technology Solutions US Inc’s (Wavefront) Primawave pressure-pulsing technology, as well as the RemMetrikSM process to quantify subsurface contamination, optimize its treatment and measure effectiveness.
Arnold Fleming, President of Fleming Lee Shue, added, “Our firm identifies and commissions innovative technologies which deliver cost effective and thorough environmental cleanup. We were very impressed with the results of VeruTEK’s S-ISCO technology implementation. Compared to full-scale excavations conducted on similar nearby sites, VeruTEK’s remedy not only reduced the project cost by over $5 million dollars but also avoided the release of dust and odor, prevented disruption to the community, and reduced the carbon footprint of the clean-up. The project was done cost effectively, completed on-time, under-budget and resulted in a Certificate of Completion.”
Dan Socci, VeruTEK’s CEO, praised the work of the combined Fleming Lee Shue and VeruTEK team that designed and implemented the S-ISCO remedy, as well as the results achieved, stating, “We are proud of the outcome of this project and had a very positive experience collaborating with Fleming Lee Shue. We look forward to repeating this project’s success and bringing a safe, effective and environmentally preferable solution to other brownfield sites, enabling their return to productive use.”
VeruTEK has successfully implemented S-ISCO at locations worldwide to treat former MGP sites, chlorinated solvents contamination—including industrial cleaning and dry cleaning chemicals, home heating oil spills, and gasoline station tank leaks. The successful destruction of MGP-related coal tar at the Hunters Point brownfield site in Queens, adjacent to the East River and in a densely developed urban setting, demonstrates the ability of S-ISCO to achieve contaminant source destruction in-situ quickly and safely for the benefit of the community and the environment.
