• Zero-Valent Iron (ZVI) in situ injections to target and treat a former dry cleaning site. 100,000-lbs of ZVI and Emulsified Vegetable Oil (EVO) amendment mixed via an above-grade injection setup to target high levels of PCE and TCE chlorinated compounds in soil and groundwater. Injected 50,000 gallons of amendment mixture, followed by performance monitoring sampling to evaluate geochemical parameters.
• Primary task manager for complex PCB cleanup project at an existing retail store in Elizabeth, New Jersey. Provided design and engineering support to implement a large-scale, waste oil free-phase LNAPL recovery process. Managed LNAPL recovery system repair, upgrade, and operation and maintenance (O&M) for ongoing PCB-impacted LNAPL recovery activities at the Site. In addition, the project included the management of methane mitigation system design evaluations, repair, and O&M activities. Work was performed in accordance with the United States Environmental Protection Agency (USEPA) Toxic Substance Control Act (TSCA) regulations.
• Lead engineer of a in situ Enhanced Reductive Dechlorination (ERD) injection event to treat chlorinated compounds in groundwater at a Vineland, New Jersey industrial facility. Project included completion of Discharge to Groundwater Permit-By-Rule Report, injection designs for dosage, and implementation of direct push injections. Injected over 20,000 gallons of activated carbon slurry during two separate mobilizations at 48 separate injection points. Results indicated contaminated reductions in all site groundwater wells near the injection area and the Site is currently in the long-term monitoring phase.
• Various Vapor Intrusion (VI) investigation and pre- and post- development construction evaluations and costing to support industrial warehouse builds. Prepare Order of Magnitude (OOM) estimate including passive and active system design options.
