EPA implicates fracking as a polution source

CHEYENNE, Wyo. — The U.S. Environmental Protection Agency for the first time has implicated fracking — a controversial method of improving the productivity of oil and gas wells — for causing groundwater pollution.

The finding could have a chilling effect in states trying to determine how to regulate the controversial process.

The practice is called hydraulic fracturing and involves pumping pressurized water, sand and chemicals underground to open fissures and improve the flow of oil or gas.

The EPA announced Thursday that it found compounds likely associated with fracking chemicals in the groundwater beneath a Wyoming community where residents say their well water reeks of chemicals.

Health officials advised them not to drink their water after the EPA found hydrocarbons in their wells.

The EPA announcement has major implications for a vast increase in gas drilling in the U.S. in recent years. Fracking has played a large role in opening up many reserves.

The industry has long contended that fracking is safe, but environmentalists and some residents who live near drilling sites say it has poisoned groundwater




When you are up to your butt in alligators, it is hard to remember your intent was to drain the swamp. Stay focused!

The EPA also emphasized that the findings are specific to the Pavillion area. The agency said the fracking that occurred in Pavillion differed from fracking methods used elsewhere in regions with different geological characteristics.

Re: EPA implicates fracking as a polution source

Here's the quandary... There are 4 new EPA rulings (Hazardous Air Pollutant/HAP, Cross State Air Pollution Rule/CSAPR, another to do with coal combustion residual disposal/CCR, and a new one forcing plants with once-through raw water cooling to convert to closed loop cooling towers- Combined the 4 rules (due to be phased in 2014-2015), plus increasing coal costs(due to expanded EPA rules on mountaintop removal mining), will cause close to 60 GW of coal power production to close down.

Now, power demand is increasing, and wind/solar can deal w/some of the shortfall but they are intermittent (that is, what the enviro-types don't want to talk about is that for every 100 MW of wind you need 100 MW of dispatchable, non-committed thermal generation to take up all the slack for the majority of the time when those resources aren't producing a single kW).

Due to EPA rules, the only feasible fuel for new generation is natural gas. This is true for the wind-chasers as well as for any new thermal capacity built. So just as there has been a massive buildout of wind power in the US, it's all for naught w/o commensurate buildout of traditional thermal.

The demand for natural gas is going to skyrocket as a result of all these new EPA rules shutting down coal and the large buildout of renewables. If the price of gas gets too high, people won't invest and we will start experiencing brown and blackouts on a regular basis, and this will happen sooner rather than later.

Watch California. they are trying to close to nuclear generating stations and have nothing in place to replace the electic the plants are generating.

Imagine that!!
... "The geology was different there"...
I'm sure they said it was perfectly safe there too...


until they found out it wasn't....

Fracking has been going on since the 1940's... It's been fairly safe... My opinion.

Re: EPA implicates fracking as a polution source

if you read the WHOLE article that timber posted, you will see there are a lot of discrepances and way more to the story

Your never to old to learn something stupid

Vertical and Horizontal fracking are two different beasts entirely. Comparing the technique used since the 40's and the current method of horizontal fracturing wells that can be in excess of a mile long is really a case of apples vs oranges.

From http://www.desmogblog.com/fracking-t...re/danger.html

Traditional hydraulic fracturing is a process that has been employed by the gas industry since the 1940s, a favorite talking point among fracking defenders.[1] Pioneered by Halliburton, the process involves the injection of water, sand and chemicals into a well to release trapped gas deposits. Hydraulic fracturing has long been used to access conventional oil and gas deposits. However, recent technological developments in drilling have opened up previously inaccessible unconventional gas deposits across North America.

Gas extraction underwent a significant technological transformation in the 1990s, when operators began using a technique developed for oil extraction: horizontal drilling.[2] [3] With the combination of hydraulic fracturing and horizontal drilling into a new technique known as High Volume Slickwater Hydraulic Fracturing, the overall scope of gas extraction has transformed, calling for unprecedented amounts of water, chemical additives and drilling pressure. Hydraulic fracturing experts like Dr. Anthony Ingraffea consider current gas drilling “a relatively new combined technology.”[4] Although industry likes to characterize the process as successfully proven for over six decades “what they fail to say is that they’ve had fewer than 10 years of experience on a large scale using these unconventional methods to develop gas from shale,”[5] Ingraffea says.

Re: EPA implicates fracking as a polution source

Its only common sense anytime you pump chemicals down past the ground water depths there will be some form of contamination..

not so sure about this premise. Horizontal drilling enables covering more ground from one well than many verticals covering the same ground. In other words one horizontal well saves many many verticales from being drilled and fluid being injected into each well aside from the surface disturbance of each and every vertical well pad.
