cirby: "Toxicology tests on the plaintiffs found the presence of toluene, benzene and arsenic in their bodies, according to the complaint."...and how much did they find in the drinking water around the site?How much was naturally occurring?What level of "contamination" was found? Parts per million? Billion? Trillion? The first rule of biased science writing: toss out a list of chemicals "found" somewhere, but not the amounts, and never tell anyone that they've been found in the water there since well before humans moved onto the continent...
Dougie AXP: I know I'm going to catch hell for this but I am an EH&S professional for a large Nat Gas operator in the Marcellus (they also operate across the company)The PADEP requires all home/water wells be tested at the cost of the company with 2000 ft of the vertical well bore before any drill bit touches the earth.Some companies test further out to be safe.The aquifers and mercellus zones are separated by THOUSANDS o feet of rock.PA was the birthplace of the oil industry in the United States and has had continuous, albeit small, oil and gas presence ever since. There are shallow gas zones (some as Low as 500 feet) all over the state. Shallow gas pockets will find the path of least resistance to the surface. Also, what do you think makes coal burn? Methane evolves off of coal seams and can leach into the ground/water with no human interaction.The geological makeup of PA is unique. To get an idea of how complex the fracture structure is take a pane of glass, spider web it and repeat that several hundred million times on top of each other.Speaking to landowners a majority of whom have no interest or leases you find out the history of the areas and routinely hear that they could see methane vents in springs and they're water wells well before the industry as a whole showed up.Someone asked who would pay for the carbon filtration systems, that would be the leasing company. In PA if there is a registered complaint and the DEP finds methane where it shouldn't be the leasing gas company is legally required to do whatever the DEP states, at a cost to the company, and provide drinking water (bottled or filtration system) at their cost until the water returns to normal. At which point the homeowner gets to keep the system for piece of mind.And for an article stating the DEP has no authority or is in the industry's back pocket, I'd like to disagree given how much they talk to us and can shut down jobs if their not completely satisfied with (which I am perfectly fine with, I've personally kicked off contractors for failing to heed my companies requirements for environmental protection).As for the makeup of frac fluids: most major players in the Marcellus use fracfocus.org to disclose fluid compositions to the public. Additionally, fluid compositions are disclosed to regulating bodies.Lastly, you want this low gas price environment and high regulation to continue. This pushes out the mom and pop shops (who are more apt to cut corners and can't afford to meet the basic requirements of environmental protection) and leaves the companies well versed in this environment to develop the needed infrastructure and best practices to do this safely and effectively./dons flame retardant suit//here we go.
BarkingUnicorn: There will be small, short-lived riots no matter who wins.
EnviroDude: If the frack wells are shallow and near the water producing sands, then they might interconnect. But my experience shows most residential water wells are shallow (Anyway, the easiest way to remove Arsenic (naturally occurring), and BTEX is to install carbon filtration systems at each of the drinking water well heads.
Girl From The North Country: I think the best course of action is to remove as many regulations from business as possible because the free market will ensure they do the right thing.
Gulper Eel: jbuist: We got ourselves an article that doesn't state any particular levels of contamination but surely the industrialists are to blame for this, uh, something, I guess.The testing appears to have been about markers more than levels. For some reason TFA didn't link to the original Times article, but here you go.I'm inclined to support fracking, if only because it's opposed in NY the same dipshiats who think Indian Point should be closed because of OMG TSUNAMI MOTHRA.
