This was in response to me fussing at the Texas GOP leadership for telling US cities and counties that they could not ban fracking anymore.<\/p>\n<blockquote><p>I think we have <a href=\"http:\/\/www.annualreviews.org\/doi\/pdf\/10.1146\/annurev-environ-031113-144051\">good and strong evidence<\/a> to put those myths to sleep once and for all, but may be I\u2019m wrong and it would be nice if he could tell me why he thinks what he thinks.<\/p><\/blockquote>\n<p>Well, I disagree. I think that the evidence holds that fracking is bad. The article that he links to there is this one:\u00a0 <span class=\"Apple-style-span\"><span class=\"Apple-style-span\">Jackson, R. <i>et al.<\/i> The Environmental Costs and Benefits of Fracking. <i>Annu.

At worst, it&#8217;s a deliberate misrepresentation of the the facts and the references there-in. I do not think that the cited article supports the claim that fracking is not harmful. This is an exceptionally long, detailed, and researched post, so be warned.<\/p>\n<p>Now, please understand, that this is not intended to be a condemnation of natural gas. While I loathe fossil fuels as only someone who grew up next to a refinery can, I understand that natural gas is better for the environment than coal. That is roughly equivalent to my preference HIV over ebola. Neither is good, but there is certainly one I would prefer catching over the other. I&#8217;ve talked a lot about renewables and my preferences should be quite obvious to any frequent reader.<\/p>\n<p>Fracking, however, is not a fossil fuel. It is a method of obtaining said fossil fuels by what is called hydraulic fracturing. In the most basic sense, a hydraulic fluid with additives is pumped into wells at very high pressure. This cracks the rocks deep in the well, allowing fossil fuels (usually light oil and natural gas) to flow more freely.<\/p>\n<p>This takes a tremendous amount of water and is the first discussion point in the paper.<\/p>\n<blockquote><p>Hydraulic fracturing and horizontal drilling require considerable water. A lateral from a single\u00a0well might be drilled 1\u20133 km sideways (see above) and divided into 20 or so \u223c100-m-long stages.\u00a0Across many plays (37), including the Barnett, Marcellus, and Fayetteville Shales, hydraulic fracturing typically requires 8,000 to 80,000 m3 (2 to 20 million gallons) of water for a single well\u00a0(Table 1). An additional 25% of water use is typically associated with drilling, extraction, and\u00a0sand or proppant mining (20); <strong>in Table 1 we use a more conservative estimate of 1,900 m3 (500,000 gallons) per well<\/strong> for these processes to account for different practices, such as whether\u00a0air drilling is used. (my emphasis)<\/p><\/blockquote>\n<p>In short, a well shaft is drilled. That shaft, which can be kilometers long, is pumped full of fluid (which is water mixed with stuff) at high pressure until the rock breaks. This article seems to accurately report the amount of water used for these operations with the knowledge that, especially for Texas, such reports are frequently not required and are industry reported. But then, inexplicably, the authors only assume one quarter of those values at the low end and less than 2% at the high end. Huh?<\/p>\n<p>Let give an example. The Barnett Shale in Texas has over 14,000 wells drilled into it. According to the referenced article (20:\u00a0 <span class=\"Apple-style-span\"><span class=\"Apple-style-span\">Nicot, J.-P. P. &amp; Scanlon, B. R. Water use for Shale-gas production in Texas, U.S.<i>Environ. Sci. Technol.<\/i> <b>46,<\/b> 3580\u20136 (2012).) the Barnett Shale, from 2000 to 2011, had consumed some 38,300,000,000 gallons of water. Which is roughly what is shown in the Table 1 referenced in the quote.\u00a0<\/span><\/span><\/p>\n<blockquote><p>Across Texas, for instance, the amount of water used for hydraulic\u00a0fracturing yearly is \u22641% of total water use (20).<\/p><\/blockquote>\n<p>I have no idea why this comment is in this article, except to provide some kind of comment for a pro-fracking person to use in a discussion. It&#8217;s a meaningless point. IF we could transport trillions of gallons of water all over the state, then, perhaps it would be a valid statistic. However, as the recent weather events of Texas have shown, we can&#8217;t move that kind of water.<\/p>\n<p>This is important, because shale oil fracturing operations are very localized in space. In spite of the huge number of wells and the vast distances a well can cover horizontally, it&#8217;s still a very local phenomenon. For example, that Barnett shale only covers some 48,000 square kilometers. The entire North Texas metro area (Dallas, Fort Worth, Denton) sits on top of this with one of the highest populations in the United States (4th in metro areas).<\/p>\n<p>The Jackson et. al\u00a0paper fails to mention some of the other stats listed by the Nicot paper they reference. Annual water use for the Barnett shale is about 9% of the water use for the city of Dallas (population 1.3 million).<\/p>\n<blockquote><p>Water use for\u00a0shale gas is &lt;1% of statewide water withdrawals; however, local impacts\u00a0vary with water availability and competing demands. Projections of cumulative net water use during the next 50 years in all shale\u00a0plays total \u223c4350 Mm3 [ed. 1,100,000,000,000,000 gallons, that a million billion], peaking at 145 Mm3 in the mid-2020s and decreasing to 23 Mm3 in 2060. Current freshwater use may\u00a0shift to brackish water to reduce competition with other users.<\/p><\/blockquote>\n<p>Now, we need to be clear about something here. Every single one of these estimates of water usage, is just that, an estimate. Texas has an unbelievable hodgepodge of environmental agencies, most with little or not enforcement powers, and a deep cultural history of promoting fossil fuel production over all other factors ( <span class=\"Apple-style-span\"><span class=\"Apple-style-span\">Rahm, D.

However, Michigan laws also largely exempt fracking from key water protection statutes, like Michigan\u2019s codification of the Great Lakes Compact.\u00a0 In fact, Michigan\u2019s codification of the Great Lakes Compact under the Natural Resources and Environmental Protection Act of 1994, <a href=\"http:\/\/www.legislature.mi.gov\/(S(zncmmg5504zy0e5550zfmc55))\/mileg.aspx?page=getObject&amp;objectName=mcl-451-1994-III-1-THE-GREAT-LAKES-327\" target=\"_blank\">Great Lakes Preservation section<\/a>, <strong>exempts the oil and gas industry from complying with the requirements of large quantity water withdrawals, including obtaining a water withdrawal permit, <a href=\"http:\/\/www.legislature.mi.gov\/(S(zncmmg5504zy0e5550zfmc55))\/mileg.aspx?page=getObject&amp;objectName=mcl-324-32727\" target=\"_blank\">stating<\/a> a withdrawal undertaken as part of an oil and gas activity are exempt withdrawals unless they result in a diversion.<\/strong> Considering that fracking has been occurring in Michigan over the past few decades, and deep horizontal well drilling has been in abundance since 2010, Michigan\u2019s laws and regulations are minimum at best. (<a href=\"http:\/\/vjel.vermontlaw.edu\/fracking-michigan-drilling-natural-gas-impact-great-lakes\/\">Vermont Journal of Environmental Law<\/a>, my emphasis)<\/p><\/blockquote>\n<p>OK, that&#8217;s a problem. We don&#8217;t actually know how much water fracking activities are using. The producers may not even know. Why would they monitor and keep records for something that they aren&#8217;t required to (and might be used in a court later)?<\/p>\n<p>But what about recycling? Surely this water can be recycled and used again or treated and then returned to the environment. Well, many people say that water can be and is being recycled, but I find it exceedingly difficult to verify such claims.<\/p>\n<p>As of mid-2014, the <a href=\"http:\/\/www.dallasnews.com\/business\/energy\/20140809-fracking-companies-begin-slow-shift-to-recycling-wastewater.ece\">Dallas Morning News reports<\/a> that<\/p>\n<blockquote><p>But estimates are that in places like the Eagle Ford and Permian Basin, 10 percent to 20 percent of the water being used now comes from recycling. And that number is expected to at least double over the next decade, said Marcus Gay, a water analyst at research firm IHS who has since left the company.<\/p><\/blockquote>\n<p>One former oil.gas consultant started a recycling business, seeing the trend. He said that, now, water might be 20%, but 2 years ago, it was zero. Further, it doesn&#8217;t make economic sense for most companies to recycle, not when they can inject the wastewater into deep wells (see a brief discussion on earthquakes below). If water is plentiful in the area, then there&#8217;s no economic sense in recycling the water. It&#8217;s only when water becomes scarce that it begins to make sense to recycle it. Once it becomes scarce for the drillers, then the non-fossil fuel users of that water are already hurting.<\/p>\n<p>Parts of the Eagle Ford shale (south of San Antonio Texas) are reporting the aquifer has dropped 70 feet in a year. Sure, some is due to agriculture. But some is also due to fracking and oil\/gas extraction. And that water, unless heavily treated cannot be reintroduced to the environment (see the discussion on toxic chemicals below). That water is now, for all intents and purposes, gone from our water cycle.<\/p>\n<p><a href=\"http:\/\/www.technologyreview.com\/news\/512656\/skipping-the-water-in-fracking\/\">Fracking can be accomplished without water<\/a>&#8230; although some technologies (to me) represent more a problem than using water. For example, propane fracking. Putting a lot of highly compressed, flammable material in a bore hole seems to be fraught with peril and letting the propane gas back out of the hole&#8230; But there are some other technologies. But so far, the watchword is &#8220;<a href=\"http:\/\/stateimpact.npr.org\/texas\/2013\/03\/27\/waterless-fracking-makes-headway-in-texas-slowly\/\">slowly<\/a>&#8221; and<a href=\"http:\/\/insideclimatenews.org\/news\/20111104\/gasfrac-propane-natural-gas-drilling-hydraulic-fracturing-fracking-drinking-water-marcellus-shale-new-york\"> in a very conservative industry<\/a>, it will take lots of time (at billions of gallons of water per year). And there are fewer regulations on these technologies than for water-based fracking (which says a lot).<\/p>\n<p>I&#8217;m not dismissing these out of hand. Of course, if water was the only issue (it&#8217;s not), then I would say go for it. But, at this point, why invest so much energy in a system that we don&#8217;t really need anymore and still isn&#8217;t going to fix global warming.<\/p>\n<p>I will also admit that there are some benefits to natural gas. For example, natural gas power plants don&#8217;t use water. So, that&#8217;s more water available for other uses (like getting the natural gas). But then, solar and wind also don&#8217;t require water.<\/p>\n<p>Going back to the Vermont Law statement. Read the first sentence again. Frackng activities are exempt from &#8220;most federal laws&#8221; for environmental protection.<\/p>\n<p>The <a href=\"http:\/\/water.epa.gov\/type\/groundwater\/uic\/class2\/hydraulicfracturing\/wells_hydroreg.cfm\">EPA<\/a> says much the same thing.<\/p>\n<blockquote><p>While the SDWA [ed.

Ethane was 23 times higher in homes &lt;1 km from gas wells (P =\u00a00.0013); propane was detected in 10 water wells, all within approximately 1 km distance (P = 0.01). Of three factors previously\u00a0proposed to influence gas concentrations in shallow groundwater\u00a0(distances to gas wells, valley bottoms, and the Appalachian Structural Front, a proxy for tectonic deformation), distance to gas wells\u00a0was highly significant for methane concentrations (P = 0.007; multiple regression), whereas distances to valley bottoms and the\u00a0Appalachian Structural Front were not significant (P = 0.27 and\u00a0P = 0.11, respectively).

However, tert-butyl alcohol is not expected to\u00a0occur naturally in ground water.<\/p><\/blockquote>\n<p>The Jackson report mentions both of these cases, but labels them &#8220;controversial&#8221;.<\/p>\n<blockquote><p>Although part of the controversy\u00a0concerns the lack of predrilling data at the site, one aspect is very different from typical practices.\u00a0Hydraulic fracturing in this tight sandstone formation occurred as shallowly as 322 m, and local\u00a0drinking-water wells were as deep as 244 m (91). A lack of vertical separation between fracturing\u00a0and drinking water increases hydraulic connectivity and the likelihood of contamination.<\/p><\/blockquote>\n<p>This is very interesting. They label it as controversial because there is no data prior to the wells being developed. So, I&#8217;m really curious what the totally natural source for things like isopropanol or gasoline and diesel.<\/p>\n<p>Further, they label them controversial, then admit that the vertical separation between the two is much smaller than the known distances that fracking can propagate.<\/p>\n<p>I know that there is much, much more to this that I could go into detail on. I&#8217;ll briefly mention the evidence for earthquakes due to fracking AND deep injection of waste. But Avant Garde says that these are small earthquakes and therefore no big deal. That&#8217;s very much a head in the sand approach to this issue.<\/p>\n<p>While it&#8217;s true that earthquakes directly due to fracking tend to be smaller (as far as we have seen), the injection induced earthquakes can reach destructive levels. The largest so far being a 5.8 magnitude earthquake in central Oklahoma that destroyed 14 houses and injured two people.<\/p>\n<p>Between 1967 and 2000 there was an average of 27 earthquakes per year larger than magnitude 3. Between 2010 and 2012, the average was 100 earthquakes greater than 3. The states with the greatest increase in seismic activity include Arkansas, Colorado, Texas, Oklahoma, Ohio, New Mexico and Virginia.<\/p>\n<blockquote><p>Several examples since 2011 highlight the\u00a0difficulty in determining whether earthquakes\u00a0were induced by human activity. The Mw 4.0\u00a0earthquake on 31 December 2011 in Youngstown,\u00a0Ohio, appears to have been induced by injection\u00a0of wastewater in a deep Underground Injection\u00a0Control (UIC) class II well (12). The Mw 4.7\u00a027 February 2011 central Arkansas earthquake\u00a0has also been linked to deep injection of wastewater (13). The Mw 4.4 11 September 2011 earthquake near Snyder, Texas, occurred in an oil field\u00a0where injection for secondary recovery has been\u00a0inducing earthquakes for years (14). The Mw 4.8\u00a010 October 2011 earthquake near Fashing, Texas,\u00a0occurred in a region where long-term production\u00a0of gas has been linked to earthquake activity (15).\u00a0For others, such as the Mw 5.7 6 November 2011\u00a0central Oklahoma earthquake (16) or the Mw 4.9<br \/>\n17 May 2012 east Texas earthquake (17), where\u00a0active wastewater-injection wells are located near\u00a0their respective epicenters, the question of natural\u00a0versus induced remains an active topic of research. ( <span class=\"Apple-style-span\"><span class=\"Apple-style-span\">Ellsworth, W. Injection-Induced Earthquakes. <i>Science<\/i> <b>341,<\/b> 1225942 (2013).<\/span><\/span>\u00a0)<\/p><\/blockquote>\n<p>These are from injection wells, not fracking wells. Injection wells are where the industry is disposing of untreatable (or too expensive to treat) wastewater from both fracking and non-fracking well processes. This water is pumped into deep wells either drilled for the purpose or into empty oil\/gas wells. This pumped water can both increase pressure and lubricate movement along faults. There are many faults in the interior of tectonic plates, but they are rarely active (the <a href=\"http:\/\/en.wikipedia.org\/wiki\/New_Madrid_Seismic_Zone\">New Madrid fault<\/a> in Missouri being a notable exception).<\/p>\n<p>For example, the Barnett Shale in Texas had zero earthquakes for the 25 year period prior to 1998. Since then, there have been 25 earthquakes greater than magnitude 3. That&#8217;s the date the production began in the field.<\/p>\n<p>The Jackson report does discuss various induced earthquake types and then notes that, for deep injection, there are 5 steps to reduce their occurrence. \u00a0So the question becomes, does the industry do these five steps? If so, then we&#8217;re still getting earthquakes, then that&#8217;s an issue. If the industry isn&#8217;t doing those five steps, then that&#8217;s a bigger issue.<\/p>\n<p>In conclusion, I am not totally impressed by the reported suggested by Avant Garde as &#8220;good and strong&#8221; evidence. Honestly, it appears to me to be little more than an attempt to spin the direction of the discussion away from fracking and into areas that aren&#8217;t under discussion (like use of water by agriculture and dams also cause earthquakes).<\/p>\n<p>In my opinion, we&#8217;re letting the fox totally guard the hen house. Every once in a while, we go out and ask the fox how many chickens we have and sometimes the fox tells us and sometimes he doesn&#8217;t. Honestly, I was surprised at the complete and utter level of control the oil\/gas industry has. While some states have no trade secret laws (like California), other states (like North Carolina) have made it felony to reveal a trade secret. Even highly environmentally conscious states don&#8217;t ask questions about the oil\/gas industry.<\/p>\n<p>My research to date has done nothing to resolve my ill-will toward fracking and the oil\/gas industry.<\/p>\n<p>My conclusion is that fracking is bad. I will, of course, reserve the right to change my opinion when new evidence and a new regulatory framework comes into existence (probably by magic, because there&#8217;s no way our current government is going to do anything about it).<\/p>\n<p><strong>References Cited:<\/strong><\/p>\n<p>Colborn, T., Kwiatkowski, C., Shuitz, K. &amp; Bachran, M.
