Between the piffle and blather put out by the oil & gas industry shills and the flakiest 2% of the ecology movement there is some ground--perhaps--somewhere far away from these not-to-be-believed extremes, where the truth lies.
Fracturing in the past didn't result in wholesale widespread contamination on a permanent basis of essential groundwater/deepwater aquifers. True....but current fracturing practices to extract oil/gas from tightly bound rock are vastly different in scope and density than the traditional fracking to get a water well, or to drill a traditional oil/gas well which is pressurized internally naturally, and trapped in a big pool under an impermiable rock shell or salt dome. Think of getting one needle for a flu shot, and then compare getting 1,784 needles all over your body at the same time to immunize you. Not the same situation at all, and the oil and gas industry is being disingenuous by saying all fracking is the same. It is except for the details, but as the saying goes, the devil IS in the details. Shale/rock fracking is such a different situation from traditional well drilling, that I'm uneasy about the consequences. After all, ground water aquifer contamination--like nuclear waste storage--is a lot closer to 'forever' than we might think. If the water took 5000 years--or even 100 years--to permeate rock down to deep water levels, just how long would toxic contaminents take to leach out again if they were artificially injected into these regions?
Water (and chemical) injection does cause earthquakes. True...but it is a matter of scale in most places. It would not be going from 1.x or so (not detectable except with sensitive instruments) to devastating 6.x or 7.x earthquakes, generally speaking. Remember, most people don't realize that the Reichter scale is logorithmic, so a 6.6 quake is ten times as strong as 6.5 which is 100 times stronger than a 6.3 and so forth. Would a sudden increase in frequency and intensity of quakes cause actual harm? It all depends on the frequency and the increase in the intensity by ACTUAL measurement in the SPECIFIC area--there is no general answer. If you are going from regular 1.6 mini adjustments once a month to 1.9 once a week, or even 2.1 daily, you wouldn't notice any of this until you were informed by the media, likely. However, if you are living in an area with clay soil, especially Leda clay, severe results can happen with relatively minor quakes, so an increase in intensity or frequency can have consequences far different from other areas, and much more than you might expect. soil liquification, landslips and slides, road/pipe breakage, subsidence, can all happen. Injecting water is just like greasing something stuck and working at it with ever larger effort; it might start moving very slowly right away (extremely minor quakes) or it might build up and suddenly give way under a lot of pressure (larger quakes)

Gas industry needs to get their acts and facts together before lobbying for any more drilling...total overall impact environmentally!!!

Oh, yeah. Like the auto industry did so well with their own regulations and the oil industry has done since they started. Shortsightedness and desire for quick money always works out so well.

BIG OIL & GAS love us
FROM THE ARTICLE:
The main presenter was Jeff Brami, a retired Exxon Mobil geologist who now heads his own consulting firm in Texas. He discussed in detail a number of API's standards related to fracking, which API distributed to attendees in three-ring binders (in photo). He praised the standards because they are based on science and "don't deal with emotion."
However, neither Brami nor any of the other presenters discussed any of the problems the gas industry has experienced despite API's standards, which include cases of water contamination near fracking sites in Pennsylvania, Colorado, Texas and Wyoming. Neither did they mention the Duke University study that found gas contamination of drinking-water wells near fracking operations, nor the Environmental Protection Agency draft study that concluded contaminated wells near a Wyoming gas drilling site "can be explained by hydraulic fracturing."
But that's not altogether surprising, given that an industry which is a master of denial still denies these findings have anything to do with fracking. For example, the Hydraulic Fracturing Primer on API's website claims that there are "zero confirmed cases of groundwater contamination connected to the fracturing operations in one million wells hydraulically fractured over the last 60 years."

Let them set their own standards.......they need the money, this is an election year.
