Ron is experienced in delivering large-scale and multi-site programs including local, regional, and multi-national programs. At a petroleum refinery, Ron delivered a multi-year program of works including site characterization, human health and ecological risk assessment, LNAPL plume stability assessment, pilot scale remedial testing, remedial option feasibility study, Cleanup Plan development, and engagement with third party stakeholders and regulators. He developed a collaborative data set from traditional, forensic and in situ measurement tools and by employing dynamic work strategies (e.g., EPA&'s Triad approach) to build conceptual site models for multiple plume areas. Ron also performed vendor due diligence for a major multinational oil and gas company exiting the Australian market. The project included technical review and baseline environmental condition summary report development for their highest potential environmental liabilities across Australia. As part of a baseline environmental conditions assessment, Ron helped an electric and gas utility evaluate and benchmark their environmental liability identification and quantification process. The scope also included developing a procedure and associated tools for environmental reserve disclosure, measurement, and tracking. He completed a comprehensive site characterization, risk assessment and remedial plan at a former iron works in Houston, Texas. Work was conducted concurrently as the site was redeveloped for mixed residential and commercial land use. The project is one of the largest brownfield projects ever completed in Houston. Additionally, Ron developed an expert report used by a natural gas producer defending a legal claim that their exploration activities resulted in methane impact to a domestic water well. The findings provided multiple lines of evidence that the methane's concentration and isotopic composition in groundwater were consistent with those expected within the natural formation and not a result of the client's activities.
To advance the state of the practice, Ron has presented at conferences on the investigation and remediation of contaminated sites, sustainable landfill closure and environmental liability reduction. He recently contributed to an emerging contaminant guidance document for the National Groundwater Association.
