GPR at a superfund (hazardous wast) site, Vermont, New Hampshire, USA

A geophysical investigation was conducted at the Parker Landfill Superfund site in Lyndonville, Vermont. The site is underlain by glacial lacustrine deposits primarily comprised of thinly to thickly bedded silty fine sand. Ground penetrating radar (GPR) was utilized in conjunction with other geophysical methods to characterize the site. Three Industrial Waste Sites, IWSI, IWS2, and IWS3, were identified as potential areas where 55 gallon drums containing solvents had been buried. GPR was used to determine the extent of the fill, characterize subsurface materials, locate buried drums and other objects, and identify buried materials which impede intrusive exploration by borings or test pits. A magnetic survey, which delineated the approximate location of ferro-magnetic materials, and test pits were conducted to assess the accuracy of the GPR interpretation.
