Ohio University B.S. Geology ’81, Queens University M.Sc. ’84

I am an Associate Vice President at the ARCADIS U.S.(opens in a new window) office in Wexford, PA, working as a Principal Geologist and Project Manager for soil, groundwater, sediment, and surface-water investigation and remediation projects, primarily located in the United States, as well as in Canada and Europe. I earned my B.S. degree from Ohio University in 1981 and my M.Sc. degree from Queens University in 1984. I toured the world for a year and began my career in 1985 at Integrated GeoSciences as a geologist/geophysicist exploring petroleum targets by electromagnetic methods in the northwest and central United States.

After returning for post-graduate studies in hydrogeology at Ohio University in 1986-1987, I began my environmental consulting career in 1987 with Groundwater Technology in the Washington, D.C. area. From 1996 until 2000, I worked with Philip Services Corp. in the Pittsburgh area. I took a position with PTS from 2000-2001 and began my current position with BBL/ARCADIS in 2001.

My career has focused on providing a broad range of consulting services to industrial clients during the performance of investigations and implementation of remedies under RCRA-/CERCLA-regulated programs. My projects include those targeting a wide spectrum of organic and inorganic constituents in all environmental media with a focus on those sites impacted by chlorinated solvents, wood-treating wastes, metals (primarily arsenic and lead), and petroleum fuels. My investigation experience includes use of a broad range of techniques, including drilling/soil and sediment sampling, well installation/groundwater sampling, geological mapping, electromagnetic geophysical surveying, subsurface geophysical evaluations, and hydraulic characterization testing via state-of-the-art techniques. I have performed these investigations in a wide variety of geological environments, including karst and fractured rock, weathered rock residuum, glacial and glacial outwash deposits, alluvial deposits, and beach deposits.

I have managed projects that used the following remediation techniques: biologically based reductive dechlorination, geochemically based metals sequestration, groundwater containment and treatment, physical isolation using engineered barriers, physical state transformation/removal, direct physical removal, and monitored natural attenuation.

I serve as the primary liaison between my project team (including nationally recognized technical experts in a wide range of fields) and clients, regulatory representatives, legal representatives, and the public. In addition, I provided, and continue to provide litigation support through expert and factual witness testimony.
