ik zeg niks win-winsituatie doeg
In Groot-Brittannië is een gigantische hoeveelheid schaliegas ontdekt. Meer dan genoeg om het land tientallen jaren van gas te voorzien. Maar de winning ervan is smerig, gevaarlijk en dus omstreden.

Jackson and his crew determined that 82 percent of the 141 water wells tested had elevated levels of methane, with other additives appearing in unusually high numbers as well. In addition to finding methane concentrations at around six times the usual level, Jackson also found ethane concentrations 23 times higher in drinking water at homes near fracking sites. In ten of the sites located within one kilometer of a drilling, propane was detected in 10 separate water samples.
“The methane, ethane and propane data, and new evidence from hydrocarbon and helium isotopes, all suggest that drilling has affected some homeowners’ water,” Jackson wrote.
Steve Everley, a spokesman for Energy in Depth, told the Wall Street Journal that Jackon’s study "is not a smoking gun to say that gas drilling is a problem."
"There is methane concentration near gas wells, but there is also methane concentrations in areas where there is no gas drilling," he said. Energy in Depth, wrote the Journal, is funded by the Independent Petroleum Association of America.
Jackson’s peer-reviewed study appeared in this week’s edition of the Proceedings of the National Academy of Sciences.
