Mark Hanish

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

Mark Hanish is an Associate Vice President at the ARCADIS U.S. 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. He earned his B.S. degree from Ohio University in 1981 and his M.Sc. degree from Queens University in 1984. Since that time, he toured the world for a year and began his 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 1986-87, Hanish began his environmental consulting career with Groundwater Technology in the Washington, D.C., area in 1987. In 1993, he took a position with Philip Services Corp. in the Pittsburgh area until 2000, at which time he took a position with PTS from 2000/2001 and took his current position with BBL/ARCADIS in 2001.

Hanish’s career focus has been 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. His 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. His 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. Hanish has 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.

Hanish’s remediation experience includes projects that he managed for which the following remediation techniques were applied: 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.

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