Yeah, cause they write something like this(google translated):

The shale gas industry has used forty chemicals in fracturing operations in Quebec:

(SAINT-HYACINTHE) The shale gas industry has used forty chemicals in fracturing operations in Quebec, said the Ministry of Sustainable Development, Environment and Parks (MDDEP), which has not yet completed its analysis of their impact on the environment.

"Until now, we had information on a quarantine of products," said Isabelle Guay, a water specialist working in the service of monitoring the state of the environment MDDEP.

Ms. Guay answered questions from the commissioners of the Bureau d'audiences publiques sur l'environnement (BAPE), who yesterday continued his study of "sustainable development of shale gas industry." "The goal is to establish the list of contaminants that may have an impact on the environment, as has been done for other industries," said Ms. Guay.

But until now, the department is far from having all the necessary information to complete its work. For now, the BAPE will be satisfied with incomplete information about it.

"We want to know their toxicity, persistence, bioaccumulation, said Ms. Guay. All this allows to establish if the products they want to avoid at the outset, and others, we want to see if there are solutions. "

"Currently, we have a list of products with chemical names," she said. It remains to be the quantities and concentrations used. "

"We also need the list of substances found naturally in rock and degradation products of the substances used. For an industry such as paper, are well known all these elements. That's why we asked for a complete list of products used. "

According to the head of environmental studies at MDDEP, Renee Loiselle, specialists have not had time to do their job. "There is no shortage of data, lack of time to analyze them," she said in an interview.

I took this from an other artickle:

The future of biogas

For its part, an expert Gaz Métro, Jean-Pierre Noël, gave his opinion on the future of biogas produced from waste or organic matter in the context of the Quebec shale gas would arrive on the market.

Biogas is more environmentally friendly than fossil fuels, but in the best case, it will not replace all of Quebec consumption of natural gas, according to Mr. Noel (Christmas. this was google:). "Current production is at best 1% of consumption," he said. In the longer term, we're talking 12 to 20% max. "The biogas alone will fail to meet our needs," he said.

Moreover, the industry has committed to make public by the end of the week's study by Secor, regarding the economic benefits it provides.

In this regard, Mr. Laliberté, the MNR said that to his knowledge, the 200 million that the industry has spent so far for its exploration work, about 20% (or 40 million) went to businesses and local services, against 80% to outside firms in Quebec. "But as as the industry will grow, there will be more local benefits," he said
