The Limestone Road Superfund Site is a Superfund site located in Cumberland, Maryland on land on both sides of Limestone Road. "The Site is located in the Valley and Ridge physiographic province of the Appalachian Highlands. The area is dominated by steeply dipping slopes and ravines and northeast/southwest trending ridges. Relief in the vicinity of the Site is approximately 1,100 feet, ranging in elevation from 590 feet above sea level at the North Branch of the Potomac River to 1,700 feet above sea level at the crest of Irons Mountain. The Site itself is located on the western slope of Irons Mountain. The elevations across the Site range from 660 feet above sea level to approximately 900 feet above sea level.".〔(【引用サイトリンク】url=http://webapp1.dlib.indiana.edu/virtual_disk_library/index.cgi/2766887/FID702/RODS/Region03/R0300292.pdf )〕 == History == In 1956, the Cumberland Cement and Supply Company bought a 191-acre piece of land next to Limestone Road. In the 1970s, the company started to allow dumping of housing material onto the property.〔(【引用サイトリンク】url=http://webapp1.dlib.indiana.edu/virtual_disk_library/index.cgi/2766887/FID702/RODS/Region03/R0300292.pdf )〕 The Environmental Protection Agency states the "properties were used for the disposal of commercial, residential, and demolition waste during the 1960s and 1970s. In 1981, approximately 110 tons of waste sludge containing chromium, lead, and cadmium were illegally dumped on both properties. In June of 1981, following an initial investigation by the State of Maryland, the property owners were ordered to clean up their respective properties. This order was eventually stayed when the EPA took over the lead at the site in 1982."〔(【引用サイトリンク】url=http://www.epa.gov/reg3hwmd/npl/MDD980691588.htm )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Limestone Road」の詳細全文を読む スポンサード リンク
