Thank you for your interest in VeruTEK Technologies. The full case study – S-ISCO® Remediation of Coal Tar Contamination at NYC Brownfield is available by following the link below:

Site: Former Roofing Products Manufacturer, Queens, New York
VeruTEK Technologies successfully destroyed coal tar contamination at a former roofing products manufacturing site in New York City using Surfactant-enhanced In Situ Chemical Oxidation (S-ISCO).  The urban site, surrounded by dense residential and commercial development along the shores of the East River, was contaminated with coal tar repurposed from a nearby Manufactured Gas Plant (MGP) for the roofing manufacturing process.

Contaminants of Concern
VOCs (BTEX) & SVOCs (PAHs and naphthalene) related to MGP coal tar in soil & groundwater
Clean-up Objectives

• Reduce contaminant mass from 10-22 ft bgs to enable issuance of Certificate of Completion (COC);
• Reduce groundwater contaminant flux.

• VeruTEK’s Surfactant-enhanced In Situ Chemical Oxidation (S-ISCO®) with VeruSOL® and alkaline-activated sodium persulfate;
• Wavefront’s Primawave pressure-pulsing injection enhancement process;
• RemMetrik characterization process.

Results

• Soil: Destroyed >90% of total contamination targeted, including 95% of naphthalene;
• Groundwater: Reduced on and off-site concentrations; no NAPL mobilized; adjacent river protected throughout;
• Soil Vapor: Significant VOC & SVOC reductions, including 100% benzene & naphthalene, and 98% BTEX;
• Technology Fusion: Successful combination of S-ISCO with pressure-pulse technology.
