Scott Drew, LSRP, an environmental scientist in Geosyntec’s Princeton office, will kick off
a breakfast seminar series
March 13 that addresses the updated Vapor Intrusion Technical Guidance of the New Jersey Department of Environmental Protection (NJDEP).
The event, sponsored by Alpha Analytics, will begin at 7:30 a.m. at the Hilton Garden Inn in
Edison, NJ. The morning series is designed to assist environmental professionals in their efforts to comply with the requirements for assessing the vapor intrusion pathway at potentially impacted sites throughout New Jersey.
Scott is among the preparers of the
vapor intrusion technical guidance for
. It was released in January 2012 and incorporates a risk-based, staged approach to the evaluation of potential vapor intrusion at impacted sites in New Jersey. He also has served on a three-man team that presented two NJDEP sponsored training seminars and webinars in February.
Scott served on the NJDEP's Vapor Intrusion Guidance Stakeholders Committee alongside state officials and a select group of individuals from industry and consulting backgrounds. Additionally, Todd McAlary, a hydrogeologist for Geosyntec’s office in Toronto, served as a technical reviewer for an earlier draft of the document. McAlary was a contributing author to the 2005 NJDEP Vapor Intrusion Guidance.
The nine-member guidance stakeholders committee convened in June 2010 and meetings were held every two weeks to prepare the revised document. A draft was released in May 2011 for public comment, generating more than 800 responses that were addressed in the final version.
Scott specializes in environmental technology, site investigation and remediation, and environmental chemistry. A
Licensed Site Remediation Professional for New Jersey
, he is currently managing projects using anaerobic bioaugmentation technology in fractured bedrock and aerobic biodegradation in a karst formation. Scott’s past experience includes projects ranging from the field demonstration of innovative approaches for the in situ biodegradation of the gasoline oxygenates MTBE and TBA, to serving as a co-investigator for a research program evaluating the biodegradation of RDX.
Todd specializes in the evaluation of contaminant fate and transport in groundwater and the vadose zone. He is especially experienced with the migration of volatile organic compound (VOC) vapors originating beneath and around buildings and the assessment of inhalation exposures from subsurface vapor intrusion to indoor air. He co-authored the first technical publication demonstrating the potential for groundwater contamination attributable to vapor diffusion and subsequent dissolution of VOC vapors into infiltrating water. He also was one of three primary authors for the U.S. EPA’s supplemental guidance on vapor intrusion and continues to lead workshops and presentations on the subject at major conferences across North America.
