Dr. Peter Zeeb, PG, LSP, principal hydrogeologist based in Massachusetts, focuses on the characterization and remediation of soil and groundwater impacted by recalcitrant and emerging contaminants of concern. He is highly experienced in site investigations, pilot tests, remedial strategy development/alternatives analyses, and full scale remedy design.

Practice Specialties
During Dr. Zeeb's 15 year professional career, he has served as the technical lead for hydrogeological, chemical fate and transport, and monitored natural attenuation evaluations. He has directed investigation and remediation strategy development at some of the most challenging sites in the country including CERCLA-regulated sites in New England and the Midwest. He has also managed numerous state-regulated sites on behalf of clients such as AstraZeneca, DuPont, Invensys, Shell, and Merck.

Advancing the State-of-the-Practice
He continues to advance the state-of-the-practice through authorship of guidance documents on protocols and assessment methodologies for natural attenuation demonstrations focusing on groundwater impacted by chlorinated solvents and the gasoline additive, MTBE. He serves as a steering committee member on the Remediation Technology Development Forum (RTDF) Source Area BioRemediation (SABRe) project, an applied R&D project located in central England designed to examine the efficacy of accelerated anaerobic bioremediation as an alternative treatment for source areas contaminated with dense non-aqueous phase liquids (DNAPLs), particularly TCE.

Academic Accomplishments
In addition to his work on guidance documents for natural attenuation demonstrations, Dr. Zeeb has authored more than 25 publications on groundwater and soil remediation, groundwater fate and transport modeling, and vapor intrusion. These publications include his doctoral dissertation on the effects of small scale subsurface features on groundwater flow and transport through wetlands, and the relationship of wetland systems to glacial aquifers. Due to the specialized focus on the geochemistry and transport of arsenic, this work was of particular importance to those responsible for protection of public water supplies.
