Reed Harris Environmental Ltd. is a consulting company specializing in services to improve the current understanding of ecosystems, and predict future responses of ecosystems to change.  Our strongest expertise is in the field of mercury cycling and bioaccumulation.

Our mission is to provide clients with more than they expect, on time, and on budget.

reed_harrisReed Harris, BSc. (Civ Eng), M. Eng., P. Eng., has over 30 years of experience in the environmental engineering field, including predicting water quality and the transport and fate of contaminants in the environment, assessing the environmental impacts of electric generating technologies, and wind tunnel and wave flume engineering.  Since 1988, Mr. Harris has specialized in the behaviour of mercury in aquatic and terrestrial ecosystems.  He has developed and applied internationally recognized models of mercury cycling and bioaccumulation in lakes, reservoirs, wetlands, marine and terrestrial systems.  Reed is currently managing a joint Canadian-US whole-ecosystem mercury addition experiment (METAALICUS) in Ontario that is examining the relationship between atmospheric mercury deposition and fish mercury concentrations (See below – Harris et al. 2007a).

Mr. Harris has done work for the private and public sectors in Canada, the United States and abroad.  He has served on expert panels, as a technical expert witness at hearings, published numerous peer-reviewed articles in scientific journals, given plenary presentations at international conferences, and was a lead editor of a book outlining a national scale mercury monitoring program (See below – Harris et al. 2007b).
