We hear a lot of shale gas in recent months. It is therefore important to have a comprehensive guidebook. Grand Algorithm so you will be happy to make the cover in 3 subjects ( The Origin , Poison and Conspiracy ).
The first issue, we made the transition ... Poof, the bubbles sort of like a bottle of Champagne ... Because yes, a first glance, technical advances have enabled the discovery of a great store of wealth that are the shale gas can dream and feast like a booty snatchers left by hackers .. . But is this money so easily won?
How the operation of the gas damages the environment?
As you read in the previous presentation techniques that can pierce the rock and release the gas is at a depth of over a kilometer, well below the water table, but it is not isolated from the ecosystem. Four factors make the operation of this gas is harmful to the environment and for people who live around.
- The cocktail used to fracture the rock and release gas: a mixture of water and sand to 99.4%, say the experts, but it remains no less than 72,000 liters of chemical carcinogens polyaclylamide ... , isopropanol, hydrochloric acid, trisodium monohydrate nitrilotriacéate. They thought dilluées these substances, when injected, then once lifts: are left in the basement of 6 to 8,000,000 liters contaminated.
- Groundwater. The geological formations are like a huge cake traveled fractures and pores. Compounds could react with each other or with other substances in the soil. Some compounds will remain underground. Experts do not really know what will happen to these mixtures which remain underground, but we now know that the lighter compounds rise to the surface. Other chemicals could also escape from the wells if the concrete jacket crack, methane and other Gas find a way to migrate to drinking water wells which makes flammable, noxious and unfit for human consumption or animal feed.
- Wastewater receding from producing wells is collected in holding tanks (not will be very safe as shown The Infoman not immune to leaks) and then transported by truck to a water treatment plant. But no study has shown that wastewater treatment plants have the ability to remove these contaminants. In addition, factories in Quebec municipalities will they be able to handle such volumes of water contaminated?
- Greenhouse effect. The Cornell University professor Robert Howarth has shown that the outcome of the operation and use of shale gas is also cleaner than coal: the dirtiest of all fuels.
So how did it go elsewhere?
Evil. No other answers. Lessons from the United States and Alberta, including documented and filmed by award-winning documentary proves it ...
- " My cow peeing blood, eyes, mouth, nose, ears and back. She plowed her belly with his hooves. My vet had never seen it. "... after drinking water contaminated with methane.
- Browse 30km 3 times a week to pick up bottled water, either centainres liters per week required, would you?
- water that sparkles like 7-Up, water flowing from the tap and that ignites a quick match.
Do we know what we do?
This money does not smell ...
Do you come more ... Next episode: how the exploitation of shale gas is not in all of Quebec's interests?
