Environmental Services

NGI and its Principal Engineers have been providing environmental site assessment, site characterization, and remediation oversight services since the late 1980s. NGI understands that the quality of its environmental services is directly related to the personnel completing the field and office services. In addition to being registered Professional Engineers, NGI’s principals have been specially qualified as Environmental Engineers in Oregon and Washington. Thomas Ginsbach, P.E., Env.E., is a Diplomat in Environmental Engineering from the American Academy of Environmental Engineers and Steve Day, P.E., Env.E holds a Juris Doctor in Environmental Law. NGI also has heating oil tank and Soil Matrix Supervisor licensing, HAZWOPER certification, as well as continued training in ASTM E1527 Phase I Environmental Site Assessments.

Environmental remedial investigations and feasibility studies completed by NGI have involved petroleum hydrocarbons, heavy metals, polychlorinated biphenyls, dioxins, pentachlorophenol, solvents, and pesticides.  NGI has overseen remedial cleanups of these contaminants that have utilized excavation with underpinning, air sparging with vapor extraction, groundwater pump and treat, bioremediation, and risk based closures.

NGI’s clients have included the U.S. Army Corps of Engineers, Oregon Department of Environmental Quality, U.S. Environmental Protection Agency, City of Portland BES, ODOT, national homebuilders, and local automotive dealerships. These clients have benefited from NGI’s ability to not only identify and characterize the environmental contingencies associated with a property but in the ability to manage the environmental cleanup and obtain agency “No Further Action” status.  Many of these remedial actions have been conducted in the Independent Cleanup Pathway of the Oregon DEQ Voluntary Cleanup Program to allow expedited site closure and subsequent timely site development.
