He designed and led site investigations and remediation actions at a site with chlorinated solvents and hexavalent chromium encompassing a one square mile using high resolution site characterization and designing in-situ remediation remedies using chemical oxidation for VOC and biochemical reduction to treat hexavalent chromium and volatile organic compounds. Richard has completed RCRA/CERCLA hazardous waste investigations/closures; implemented in-situ innovative recirculation well technology to capture, treat and reinject remediate groundwater within the same well; identified and developed high yielding groundwater supplies in surficial and bedrock aquifers; completed numerous hydrogeologic evaluations and groundwater models; and has provided depositions, bench and jury expert testimony regarding litigation issues. Most recently, Richard leads GZA’s PFAS initiative and has participated on CT PFAS Task Force Committees. Since 2015, Richard has been an active member on the Interstate Technology & Regulatory Council (ITRC) “Characterization and Remediation in Fractured Rock”, “Optimization of In-Situ Remediation and Injection Strategies” and “Per- and Polyfluoroalkyl Substances (PFAS)” teams. Richard earned a bachelor's degree in Geology from Northeastern University in Boston, Massachusetts in 1982.
