ATSDR Leroy Township report finds elevated well water chemicals – Exact cause of elevated levels unclear Press Release by The Agency for Toxic Substances & Disease Registry, November 07, 2011
The Agency for Toxic Substances and Disease Registry (ATSDR) investigated the water quality of seven residential wells surrounding the Chesapeake ATGAS 2H natural gas well site in Leroy Township, Bradford County, Pa., at the request of the U. S. Environmental Protection Agency (EPA) following a well blowout. One of the seven wells, Well No. 4, showed a 10-fold increase in methane and various salts, compared with samples taken in July 2010, before natural gas drilling began at the site. These chemicals are consistent with those expected to be mobilized from natural gas extraction activities.
