Todd Creamer, P.G.

Todd Creamer is a Principal Geologist based in New England with more than 20 years of experience in environmental consulting services, surface water hydrology, and oil and natural gas exploration and production.

His work has focused on the characterization of and remedial strategy for industrial, institutional and residential properties impacted by chlorinated solvents and petroleum hydrocarbons. Specializing in vapor intrusion of volatile compounds into indoor air and LNAPL behavior in porous media, his technical experience includes complex regulatory negotiation, construction of conceptual site models, vapor intrusion field methods development, LNAPL mobility modeling, and site characterization using hydro-geologic and advanced geophysical methods.

Todd's client service has included oversight, strategy formulation, and participation in public outreach on Department of Defense and litigious projects involving former industrial facilities with historical releases of chlorinated solvents or LNAPL to the subsurface and groundwater impacts extending into residential areas. He has conducted extensive field investigations at these sites under public scrutiny. Recent technical challenges have included mitigation of vapor intrusion to offsite residences, groundwater remedy implementation under major traffic arteries and construction of a subterranean structure by a third party in a downgradient contaminant plume.

Since 2005, Todd has been involved in multiple applied research projects with Department of Defense and academic partners including Professor Paul C. Johnson. Through technical presentations to agencies and in public forums on these and other projects, he is contributing significantly both to the national discussion on subsurface contaminant vapor behaviors near structures and to the availability of innovative assessment tools such as quantitative passive samplers, high volume sub-slab sampling and building pressure control. Todd was an invited instructor for the 2015 Massachusetts Licensed Site Professional's Association for-credit course on vapor intrusion, reaching 500 professionals. He is the Fundraising Chairman for the Piscataqua Post of the Society of American Military Engineers.
