Steve Lipsky of Parker County, Texas, holds photographs of his well water burning during a briefing organized by anti-fracking groups at the Cannon House Office Building on Capitol Hill February 5, 2014 in Washington, DC. Lipsky's water well was the subject of an EPA emergency order after he says it was contaminated by oil and gas exploration. People from communities affected by underground hydraulic fracturing used to extract natural gas, or fracking, called on members of Congress, the Environmental Protection Agency and President Barack Obama to continue investigating the connection between fracking and residential water contamination.
