The extraction of shale gas--natural gas found in deep layers of shale rock formations--is on the rise in many states. Gas drilling companies will likely drill tens of thousands of wells by 2020. The Obama administration's Blueprint for a Secure Energy Future identifies shale gas reserves as an important new energy source as the U.S. transitions from its heavy reliance on oil to a "clean energy future."
Depending on where and how it’s done, natural gas drilling does have the potential to impact Pennsylvania’s waterways, an independent study reveals.
Report date: July 2015. The exploration of unconventional shale energy reserves and the extensive use of hydraulic fracturing during well stimulation have raised concerns about the potential effects of unconventional oil and gas extraction (UOG) on the environment.
Report date: June 2015. The U.S. Congress urged the U.S. Environmental Protection Agency (EPA) to study the relationship between hydraulic fracturing and drinking water.
Report date: April 2015. This assessment provides a review and synthesis of available scientific literature and data to assess the potential for hydraulic fracturing for oil and gas to impact the quality or quantity of drinking water resources, and identifies factors affecting the frequency or severity of any potential impacts.
Report date: April 2015. New techniques of high-volume hydraulic fracturing (HVHF) are now used to unlock oil and gas from rocks with very low permeability. Some members of the public protest against HVHF due to fears that associated compounds could migrate into aquifers.
Sep 2014. Methane in water bores is a major concern in areas of coal seam gas (CSG) development. There are risks associated with ignition and asphyxiation in closed spaces around bores that create real concern. There are also other risks, such as gas lock in pumps, colour and odour impacts from water quality changes, toxicity due to other gases and build up of gases affecting the integrity of the bores.
14 leading US fracking companies used over 2,500 products. More than 650 contain chemicals that are known or possible human carcinogens, are regulated under the Safe Drinking Water Act or listed as hazardous air pollutants.
This report outlines over 60 instances of water contamination & fugitive methane migration from gas drilling operations caused by the failure to contain well pressure, faulty production casing or accidental drilling into other abandoned or producing gas wells.
A detailed look at some of the effects of gas drilling on environment, communities and health. Based on investigations, findings, and statements of state and federal regulators.
