"Last year, Jean-Louis Borloo, then Minister of Ecology granted exploration contracts with oil companies on one-tenth of the country's surface. He amended the mining code to relax environmental protection legislation and to keep secret the results of these explorations, "he explains. According to François Mandil, the area of Pontarlier would not be spared. An exploration permit would have already been signed in 2010.

The "Wikileaks" of shale gas on radioactivity
The gigantic survey on shale gas published by the New York Times is a new bomb launched on this extraction technique against which the mobilization grows in France. Not only is the evidence of health effects increasing, but the investigation reveals that the water released by the wells is radioactive.
The US newspaper has spent a lot of time deciphering 30 000 pages of confidential documents from the US Environmental Protection Agency, the EPA, and from various industry sources. is procured. A method "in the manner of WikiLeaks", but with the professionalism of the newspaper teams, who added to the raw data:
* an interactive computer graphics: a map shows the radioactivity present in 149 of some 200 wells installed in the State of Pennsylvania and lists 42 wells whose rejected water exceeds the authorized norm for radium drinking water, 4 in the case of uranium, 41 in the case of benzene, 128 exceed them for "gross alpha" (radiation caused by uranium and radium emissions);
* a video report where Rocky Mountain residents (Colorado) are forced to move because shale gas has "poisoned" them. Nausea, diarrhea, nosebleeds ... they say they are contaminated by leaks from extractions around their homes;
* and an excel file of analysis of more than 200 samples taken in the wells: the radium and uranium levels are mentioned as well as the carcinogenic benzene.
Hydraulic fracturing, the technique of mini-earthquakes
To fully understand how extraction can affect health, we need to keep in mind the whole special process of hydraulic fracturing, the unconventional method of extracting natural gas from very deep geological pockets.
As the infographic explains, the derricks temporarily installed on the surface dig a well several thousand meters underground, a vertical and horizontal well (L-shaped) at the place where the gas is present.
Sometimes drilling goes through groundwater. Cement is used to seal the well, but it may be porous and chemicals injected to explode the rock contaminate groundwater (those used for drinking water).
The technique of hydraulic fracturing provokes an explosion of permeable rock thanks to the injection of millions of liters of water laden with chemicals at very high pressure, a method which is similar to the creation of a mini-earthquake. Earth.

Let's go back to Poland. How is the situation today?
Everything went very fast, and at the same time the way in which the public authorities implemented the process seems reasonable. Very quickly: a hundred licenses have already been distributed, representing almost half of the Polish territory: 150000 km2 (on 330000). End 2011, about fifteen exploratory drilling had been undertaken.
In total, 40% of the licenses were awarded to Polish companies. The rest went mainly to large Anglo-Saxon groups in Statoil (Norway), the Japanese. On the Polish side, there are three main actors. The first is PKN (Polski Koncern Naftowy), a company that specializes in refining and distribution, which is its first opportunity to go upstream. They put a lot of effort into promoting their technology and the precautions they were going to take. They got seven licenses and started two holes. The second is Polskie Górnictwo Naftowe i Gazownictwo (PGNiG), a public company based in Warsaw who has her experience and obtained 17 licenses. They are now advanced enough to evoke production start dates, to 2013-2014 - that is, tomorrow!
