Winning van schaliegas kan drinkwater vervuilen

Update[*]: hydraulic fracturing kan leiden tot stromen radioactief afvalwater en kankerverwekkend drinkwater



Het Brabants Dagblad meldt vandaag: 'Als Brabant Resources in de Boxtelse bodem naar schaliegas op zoek gaat, worden er chemicaliën gebruikt en drinkwater om naar dat gas te boren. Dinsdagavond hadden onder meer D66 en CDA in de Boxtelse gemeenteraad een aantal zeer technische vragen aan wethouder Peter van de Wiel over het boren naar schaliegas.'

In Amerika is het winnen van shale gas door middel van hydraulic fracturing ('fracking') in de buurt van drinkwatervoorraden inmiddels zeer omstreden geworden, met name betreffende de grote voorraden gas bij en onder New York en Pittsburgh. De zorgen over verontreiniging van drinkwater door chemicaliën en zelfs dieselolie - die soms illegaal wordt ingespoten - zijn groot. Zie bijvoorbeeld:

Engelstalige en Nederlandstalige wikipedia over boren naar schaliegas.
Nederlandse wiki: Tweede Kamerlid Van Tongeren (GroenLinks) [heeft in 2010] vragen gesteld aan de minister van Economische Zaken over de winning van onconventioneel gas in Nederland. In het antwoord verwijst de minister naar het staatsbedrijf Energie Beheer Nederland dat een 40% belang heeft in de ondernemingen die de boringen uitvoeren. Verder geeft de minister aan dat er voor het 'kraken een heel klein percentage chemicaliën wordt toegevoegd aan het water en zand'. De minister geeft toe dat 'de samenstelling van de chemicaliën is vaak bedrijfsgeheim, omdat deze mede het succes en de effectiviteit van het "kraken" bepaalt. De concurrentie op deze markt is groot. De toezichthouder SodM krijgt wel inzicht in zowel de kwantitatieve als kwalitatieve samenstelling van de chemische additieven die gebruikt worden'.

Ongehoord dat we dus niet eens mogen weten wat voor rotzooi de bedrijven de bodem inspuiten om het gas te winnen![**]

Ik ben benieuwd hoe kritisch de vragen van D66 en CDA waren en of men goed op de hoogte is van de ontwikkelingen in de VS rond de gevaren van deze vorm van gaswinning.

Ook schaliegas is niet vrij van milieubezwaren

Steeds meer gemeenten tegen schaliegasboringen
Persbericht Milieudefensie, 21 september 2012

De winning van schaliegas is omstreden omdat de boringen kunnen leiden tot aardbevingen en vervuiling van grond- en drinkwater. De klimaateffecten kunnen nog negatiever uitpakken dan bij kolen. Bovendien is schaliegas een fossiele brandstof, die niet past in de noodzakelijke overstap naar duurzame energie.

Chemicals From Marcellus Shale Fracking Could Reach Surface In ‘Just A Few Years,’ Study Finds

Scientists have theorized that impermeable layers of rock would keep the fluid, which contains benzene and other dangerous chemicals, safely locked nearly a mile below water supplies [...] But the study, using computer modeling, concluded that natural faults and fractures in the Marcellus, exacerbated by the effects of fracking itself, could allow chemicals to reach the surface in as little as "just a few years."

Frack this: More dangers to public health from natural gas hydraulic fracturing emerge
Door Tom Kenworthy, CAP / Climate Progress, 7 maart 2011

In its second story, the Times charges that recycling of the wastewater produced during drilling also entails risks to public health and the environment:
'Some methods can leave behind salts or sludge highly concentrated with radioactive material and other contaminants that can be dangerous to people and aquatic life if they get into waterways. Some well operators are also selling their waste, rather than paying to dispose of it. Because it is so salty, they have found ready buyers in communities that spread it on roads for de-icing in the winter and for dust suppression in the summer. When ice melts or rain falls, the waste can run off roads and end up in the drinking supply.'

'Fracking' Comes to Europe, Sparking Rising Controversy

As concerns grow in the U.S. about fracking to extract natural gas from shale, companies have set their sights on Europe and its abundant reserves of this "unconventional" gas.

Hydraulic Fracturing Process Dangerous for the Environment
Door Emily Kennedy, Mother Earth News, 1 oktober 2010

(...) Hydraulic fracturing, also known as hydrofracturing or hydrofracking, is a process used to increase the water flow from a bedrock well. This process occurs when the size of the fractures in bedrock is increased so that more water can enter into the well. Some drilling companies argue that hydrofracking costs less than, and is a better alternative to, drilling deeper. However, according to the January 4, 2010 newsletter issue for the Center for Health, Environment & Justice titled “Growing Opposition to High Risk Hydrofracking Technology”; many scientists are opposed to the process because of the high levels of radium it releases into the environment. The newsletter also states that “water brought thousands of feet to the surface from drilling had levels of radioactive radium – 226 as high as 267 times the limit safe for discharge into the environment.

Disclosure of chemicals in gas fracking advances
Door Tom Kenworthy, Climate Progress, 3 december 2010

(...) this week, three oil and gas industry trade associations – America’s Natural Gas Alliance, the Independent Petroleum Association of America and the American Exploration & Production Council – announced their support for the establishment of a fracking chemicals registry being developed by the Ground Water Protection Council and the Interstate Oil and Gas Compact Commission. Though participation in the registry would be voluntary by individual companies, it still represents a meaningful, if incomplete, step. Obviously, the energy industry is beginning to read the writing on the wall as far as public disclosure is concerned.

EPA Wants to Look at Full Lifecycle of Fracking in New Study
Door Nicholas Kusnetz, ProPublica, 9 februari 2011

The EPA has proposed examining every aspect of hydraulic fracturing, from water withdrawals to waste disposal, according to a draft plan. If the study goes forward as planned, it would be the most comprehensive investigation of whether the drilling technique risks polluting drinking water near oil and gas wells across the nation.

The agency wants to look at the potential impacts on drinking water of each stage involved in hydraulic fracturing, where drillers mix water with chemicals and sand and inject the fluid into wells to release oil or natural gas

    Weer heerlijk staaltje dom denken. Het gaat maar om 'kleine percentages'... Nou en. 1% van ontzettend veel is nog steeds veel. En die troep die ze inspuiten wordt niet na afgebroken, maar komt wel in het grondwater terrecht...
    Zo moeilijk is het niet.
