Dave Parkinson is a Principal Scientist based in Washington with more than 20 years of environmental consulting experience focused on a wide variety of groundwater, surface water, water resources, environmental site investigation, characterization, and remediation projects.


Dave provides project and technical lead on site characterization, remedial feasibility, and implementation. He has led pilot and full-scale thermal remediation projects that require significant site characterization and has utilized innovative technologies for understanding technology implementation. The types of projects range from development and implementation of Total Maximum Daily Loads (TMDLs) for stream restoration, to allocation support for CERCLA sediment mega-sites. He has prepared and reviewed a number of modeling efforts aimed at understanding quantity, quality and impacts to and from both groundwater and surface water.

Site characterization and understanding has been a central aspect of the work Dave pursues. He has performed numerous site investigations, developed remedial investigations, and evaluated site data. In addition, he provides litigation and allocation support based on review and understanding of complex site characterization data.

Dave has been involved with thermal remediation projects for over twenty years. He has participated on expert panels as well as overseen the successful deployment of thermal remediation systems in a variety of challenging hydrogeological and logistical environments. He led the design and implementation of the steam pilot project at LC34 Cape Canaveral Air Station for the Interagency DNAPL Consortium. He also led the design team and provided support for construction and operations for the steam remediation project at Department of Energy Savannah River Site M-Basin.

Water resource and water quality projects Dave has been involved with include investigation and design of artificial recharge of aquifers, groundwater modeling of recharge impacts, geochemical modeling of groundwater impacts of artificial recharge, review of groundwater-surface water interaction models, and the review of surface water models for the development of TMDLs.
