Un ONG de la province, The Conservation Council of New Brunswick, explique ses inquiétudes face à la nouvelle technique d'extraire le gaz naturel du roc près de la ville d'Elgin. Se basant sur ce qui se passe déjà aux États-Unis dans plusieurs états, on peut se rendre compte de contamination de puits d'eau potable, une réduction de la disponibilité d'eau potable et la pollution de l'air. Quand le forage s'intensifie, l'industrialisation de la communauté est inévitable.
Apache Corp., une compagnie du Texas, commencera à forer pour du gaz naturel et explore de plus belle depuis qu'on a découvert des nouvelles sources de gaz naturel l'automne passé. Corridor Resources a annoncé au mois de mai que des puits conventionels abandonnés pourraient fournir plus de gaz grâce à la fracturation hydraulique. Si on découvre assez de gaz, on pense forer jusqu'à 480 nouveaux puits.
Le département de l'environnement de la province doit donner son aval avant. Mark Glynn, le directeur des procédés industriels dans le département de l'environnement dit que les lois existantes encadrent bien les risques. "Les puits eux-mêmes sont 2 kilomètres de profond ou plus. Les matériaux qui restent à 2 kilomètres de profondeur seraient certainement séparés de n'importe quelle aquifère d'eau potable. Il n'y aurait pas de trajectoire d'exposition."
Ce n'est pas tellement ce qui se passe à 2 kilomètres de profondeur qui m'inquiète, c'est ce qui se passe à la surface!

"Drilling process concerns N.B. environmentalists
The Conservation Council of New Brunswick is raising concerns over a new technique that will be used extract natural gas from shale deposits located near Elgin. David Coon, the policy director for the Conservation Council, said the hydrofracking process raises environmental concerns. "Based on what's happened already across the United States, in a number of states, there's contamination of well water, reduction in supply of water from water withdrawals, air quality problems," Coon said. "When you start to get a lot of drilling activity, the industrialization of the local community where the drilling is intense."
Apache Corp., a Texas company, will begin drilling for natural gas and it's a ratcheting up of exploration following some promising finds last fall. Corridor Resources announced in May that a formerly abandoned well could have more natural gas than is available in all of western Canada's proven reserves. If sufficient gas is found Apache Corp. and Corridor Resources could team up on drilling as many as 480 new wells.
Drilling plans have to be cleared by the province's Department of Environment. Mark Glynn, the manager of industrial processes with the environment department, said existing regulations cover the risks. "The wells themselves are two kilometres or deeper. Material that remains down two kilometres below would certainly be separate from any drinking water aquifers. There wouldn't be an exposure pathway," Glynn said."

It's not so much what's going on 2 km deep that worries me! It's what's happening on the surface!
