Beaver Run Reservoir (also known as Beaver Dam Reservoir) is a reservoir in Westmoreland County in the U.S. state of Pennsylvania, 23 miles east of Pittsburgh. The elevation of Beaver Run Reservoir is 1053 feet above sea level.〔 The reservoir is the source of drinking water for 150,000 people, including those in Murrysville, Export and Delmont. 〔(Company cited after fracturing fluid spill at Beaver Run Reservoir ), ''Trib Live'', July 31, 2013, Daveen Rae Kurutz.〕 Fishing in the reservoir and hiking near the reservoir are not allowed, due to public health concerns.〔(Fracking at Drinking Water Source for 80,000 Pennsylvanians Raises Alarms ), ''InsideClimate News'', 20 July 2011, Anthony Brino.〕 ==Gas drilling== The Municipal Authority of Westmoreland County (MAWC),〔(Municipal Authority of Westmoreland County )〕 the local water utility, leased the watershed in 1999 for gas drilling, and about 100 shallow gas wells have been drilled since then.〔 And in 2008, deeper drilling and fracking for gas in the Marcellus shale began near the reservoir.〔 As of 2013, 41 deep wells have been drilled on 6 pads.〔 The drillers are Consol Energy's CNX Gas. Some of the chemicals used by Consol for fracking have been listed online by the MAWC.〔(Municipal Authority of Westmoreland County Marcellus Shale Updates )〕 There is no information on the location, date, or total quantities of chemicals used, but Material Safety Data Sheets discuss the hazards and properties of these chemicals and others: * hydrochloric acid; * DAP-901-1, which contains methanol and phosphoric acid, and other toxic chemicals; * DWP-938-1, which contains methyl alcohol and other toxic chemicals; * DWP-944-3, which contains polyethylene glycol and other toxic chemicals; and * crystalline silica. In June 2013 there was a spill of 100 gallons of recycled frack wastewater into the ground at a pad near the reservoir. To limit pollution from the spill, soil was excavated, and testing for chlorides was done, and the tests indicated acceptable chloride levels. Fracking resumed several days later.〔(June 1, 2013 Leak on Kuhn’s Pad ), author unknown.〕 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「Beaver Run Reservoir」の詳細全文を読む スポンサード リンク
