Fracking: Should We Worry?

In an earlier post I forgot to ask what research had been done to identify and justify the use of  solvents and waste water in fracking the shale below the water table.  The oil bearing shale is thought to be well below the water table and the process is shown in the video 

Safe fracking…  There may be other views on the effects of fracking: Problems with fracking…

There have been other issues such as earthquakes in some areas: Huffington Post article…

Gas Well Spews Polluted Water

By THE ASSOCIATED PRESS, Published: April 20, 2011 
ALLENTOWN, Pa. (AP) — A blowout at a natural gas well in rural northern Pennsylvania spilled thousands of gallons of chemical-laced water on Wednesday, contaminating a stream and forcing the evacuation of seven families who live nearby as crews struggled to stop the gusher.

The Chesapeake Energy Corporationlost control of the well site near Canton, in Bradford County, around 11:45 p.m. Tuesday, officials said. Tainted water continued to flow Wednesday afternoon, though workers finally managed to prevent any more of it from reaching the stream.

No injuries were reported, and there was no explosion or fire.

Chesapeake said a piece of equipment failed late Tuesday while the well was being hydraulically fractured, or fracked. In the fracking process, millions of gallons of water, along with chemical additives and sand, are injected at high pressure down the well bore to break up the shale and release the gas.

State environmental regulators were taking water samples from the tributary of Towanda Creek, which is stocked with trout.

The blowout comes amid a natural gas drilling boom in the Marcellus Shale formation.

About carlos

I'm a curious person, of reasonable intellect, "on the beach" (retired) and enjoying my interest in anthropology, language, civil rights, and a few other areas. I've been a hippie/student/aerospace tech writer in the '60s, a witness to the Portuguese revolution in the ‘70s, a defense test engineer and witness to the Guatemalan genocide in the '80s, and a network engineer for an ISP in the '90s. Now I’m a student and commentator until my time is up. I've spent time under the spell of the Mesoamerican pyramids and the sweet sound of the Portuguese language. I've lived in Europe, traveled in Brazil, Central America, Iceland, New Zealand, and other places. My preferred mode of travel is with a backpack and I eat (almost) anything local. Somehow, many of the countries I have been to have had civil unrest (for which I was not responsible). I'm open to correspond with anyone who might share my liberal, humanist interests. I live in San Buenaventura, California.
