Hydrofracking is increasing the availability of natural gas in the Marcellus shale region that runs through much of Mid-Atlantic states west of New Jersey and into Ohio. Hydrofracking involves pumping a mix of water and various chemicals, including biocides and surfactants into deep wells under high pressure to displace natural gas. Much of the hydrofracking fluid is recovered, and the recovered fluid additionally includes brine, metals, and normally occurring radioactive material. Accidents and non-compliance associated with hydrofracking may contaminate aquatic food webs with metals and organic contaminates that are harmful to wildlife.
