==Refuting EPA's finding that fracking pollutes groundwater==
In December, 2011, the [[U.S. Environmental Protection Agency]] definitively linked groundwater contamination in Pavillion, Wyoming, to hydraulic fracturing ("[[Fracking|fracking"]]) activity taking place in the area of the aquifer.<ref>Dominic C.

==Price fixing allegations==
In June 2012 Reuters reported that, under the direction of CEO [[Aubrey McClendon]], [[Chesapeake Energy]] plotted with top executives of competitor EnCana to suppress land prices in the Collingwood Shale formation in Northern Michigan. In emails between Chesapeake and Encana Corp, the rivals discussed dividing up Michigan counties and private landowners to avoid bidding against each other in a 2010 public land auction and in at least nine prospective deals with private land owners. Price-fixing between competitors is illegal under the [[Sherman Antitrust Act]]. In Michigan alone, the two companies combined hold more than 975,000 acres of land - an area about the size of Rhode Island.<ref>Brian Grow, Joshua Schneyer, and Janet Roberts, [http://www.reuters.com/article/2012/06/25/us-chesapeake-land-deals-idUSBRE85O0EI20120625 "Special Report: Chesapeake and rival EnCana plotted to suppress land prices,"] Reuters, June 25, 2012.</ref>
