Apr 26, 2012 Site 3 is a West Virginia Dolomite quarry with in excess of 10,000 gpm (38,000 L/min) of river inflow at 120 feet (37 m). This is the site of North America's largest bitumen grout curtain in karst limestone. A new conduit developed adjacent to the remediated feature. The local geology is Tomstown dolomite-Antietam sandstone.
karst-forming rocks. Karst is a type of topography that is formed on limestone, gypsum, and other rocks by dissolution that is characterized by sinkholes, caves, and underground drainage regions. Karst areas constitute about 10 percent of the land surface of the world (fi g. 1) (Drew, 1999), and there is widespread concern
