Peter Dollar is a Principal Hydrogeologist based in Ontario with more than 20 years of experience focused on site characterization, remediation strategy, remedial design and implementation, and risk management. In particular, his professional practice focuses on the characterization and remediation of sites impacted by chlorinated solvents, petroleum hydrocarbons, and metals in soil and groundwater.
His technical expertise is focused on the geochemistry of contaminated soils and groundwater, and contaminant fate and transport in porous and fractured media, with a particular focus in assessment and remediation of chlorinated solvents and other dense non-aqueous phase liquids in soil and groundwater at industrial sites. .
With practical experience spanning North America, South America, the United Kingdom, Europe, and Australia, he has consulted with clients on the implementation of in situ permeable reactive barriers, in situ chemical oxidation, and enhanced in situ bioremediation for treatment of chlorinated solvents. He also specializes in remediation project management; full-scale implementation of newly emerging remedial technologies at impacted sites; and risk-based redevelopment of client sites. His project management experience encompasses site investigations, evaluation and selection of remedial alternatives, and remedial design and implementation in a wide range of regulatory environments.
To advance the state of the practice, Peter continues to serve as managing director of SiREM, a laboratory formed in 2002 in response to the growing demand for bioremediation treatability studies and bioaugmentation. SiREM began as an offshoot of contract laboratory treatability and microbial culture development work being performed at the University of Toronto. Simultaneously, a license agreement with DuPont Corporation was formed that laid the groundwork for commercialization of SiREM's Gene-Trac molecular testing service.
