Over the past decade, Dan has grown his practice to help new clients with environmental investigation and remediation. Beginning with a field pilot of the nanoscale zero-valent iron (nZVI) technology at their Trenton, New Jersey HVAC products facility, Dan was instrumental in assisting American Standard Inc. (Trane) and Ingersoll Rand with a multi-project remediation portfolio. Dan has spearheaded Geosyntec's government liaison and other efforts in ongoing brownfields redevelopment work at the Somerville landfill on behalf of the Borough of Somerville. As a consultant, Dan guided UNC-CH through a voluntary cleanup program for impacted soils at its cogeneration facility. He also helps lead a portfolio of projects with BASF, including several complex environmental investigations and remediation projects at current and former manufacturing sites throughout the U.S. Currently, Dan is leading a demonstration project involving a combined remedy featuring BASF's carbonyl iron powder (CIP) deployed with enhanced in situ bioaugmentation to treat chlorinated ethenes and methanes-impacted groundwater at BASF's 355-acre flagship facility in Geismar, Louisiana. Also, Dan is managing a unique project with Pfizer to assess losses of active pharmaceutical ingredients (API) to wastewater in their global supply chain.
Dan was a member of the Project Advisory Group of NANOREM, a consortium of universities, national research labs, and industry focused on developing and applying nanoscale environmental remediation technologies at brownfield sites throughout the European Union. He has co-authored numerous articles on the nZVI technology and applications in peer-reviewed journals and is a regular speaker at conferences in the United States, Europe, and China. He has extensive knowledge of environmental chemistry involving the fate and behavior of organic contaminants including pharmaceutical actives and intermediates. Dan is also a recognized expert in the chemistry, fate, transport, and treatment of the hexachlorocyclohexanes (HCH).
