HVHF timeline in the US


Hydraulic fracturing is used to extract natural gas for the 1st time

1/1/1947 - 1/2/1947

EPA rules that fracking doesn't fall under Safe Drinking water act

1/1/1974 - 1/2/1974

Therefore fracking operations are able to proceed unhindered

Horizontal drilling is used with hyrdaulic fracturing

1980 - 1990

1st done in a frack job in Northern Texas

Fracking in Alabama leads to lawsuit against EPA

1/1/1996 - 12/1/1996

The lawsuit alleged that the injection of fluids for fracking must be monitored by the EPA under the SDWA

The current method of fracking is used from the 1st time

Used first in the Barnett Shale in Texas. This now allows formerly inaccessible gas reservoirs to be open for fracking

House explodes due to gas buildup in Pittsburgh, PA

EPA reports that fracking fluids are toxic

6/1/2004 - 6/2/2004

EPA reports that some portion of these toxic fluids remain in the ground after a frack job. However, report concludes “injection of hydraulic fracturing fluids into coal bed methane wells poses little or no threat” to drinking water supplies.

7/3/2005 - 7/4/2005

Citing the EPA’s 2004 study, Congress passes Energy Policy Act of 2005, exempting fracking from the SDWA

EPA issues plan to study potential impacts of fracking

11/2/2011 - 2014

By request of the U.S. Congress, the EPA issues a Plan to Study the Potential Impacts of Hydraulic Fracturing on Drinking Water Resources, to be completed by 2014.
