Dave Sherman is a Principal Geologist based in Pennsylvania with more than 20 years of environmental consulting experience focused on site investigation, groundwater assessment and remediation, and vapor intrusion (VI) evaluation and mitigation.


Dave has managed and planned numerous projects, including hydrogeologic investigations; large-scale compliance and performance monitoring programs; subsurface vapor intrusion assessments; analytical and numerical groundwater modeling; air monitoring; and several diverse environmental due diligence and remediation projects. His clients are within both the public and private sectors, and comprise major industry players as well as municipal, state and federal agencies. Dave has expertise with site-wide strategies, hydrogeologic evaluations, remedial characterization, data analysis and interpretation, risk assessment, conceptual site modeling, and site closures. He is proficient with a variety of remedial construction and oversight work including building demolition, UST installation and removal, soil and sediment excavation and disposal, and health and safety. He has familiarity with many hydrogeological and geophysical methods including ground penetrating radar, resistivity testing, downhole geophysical technology, packer testing, rock coring, and geologic logging techniques. Dave is also knowledgeable about operations and maintenance of groundwater remediation systems including groundwater extraction and treatment, multi-phase extraction, biosparging, and bioslurping. In-situ bioremediation and chemical oxidation are also remediation technologies with which he has great familiarity.

Among Dave’s key benefits to clients is his experience in sitewide and remedial strategy development, RI/FS evaluations, pilot testing and remedial design, site investigation and characterization, vapor intrusion assessments, and remedial and regulatory communication and negotiations. Dave has assisted clients who are regulated under a variety of frameworks, including RCRA, CERCLA, state-lead, and voluntary cleanup programs across the Northern Regions, including New York, New Jersey, Pennsylvania, Delaware, West Virginia, and Maryland. To better assist his clients, Dave develops cost-effective alternatives to conventional remedial approaches that take advantage of the latest technologies and innovative applications of existing technologies while achieving regulatory acceptance to address contaminants within complex geologic settings.

Dave has also directed and managed soil and groundwater remediation work, using state of the art investigation methods, at numerous commercial, industrial, and residential locations throughout the United States. During which, he has developed various Community Relations and Notifications Programs, attended public meetings, and provided demonstrations of SI/RI/RA techniques to multiple regulatory agencies.

To advance the state of the practice, Dave’s efforts have focused on the development and implementation of site-specific risk management strategies for commercial and industrial facilities.

These strategies combine the elements of human health and ecological considerations with regulatory and engineering factors as well as industry standards to obtain integrated risk analyses and management solutions. He is an active participant in Geosyntec’s internal groundwater practice group.
