The Cowichan River could run bone dry before the end of the month if rain doesnt start falling by the bucketful, raising concerns for environmentalists, municipal officials and representatives of the nearby paper mill. Globe and Mail, October 7, 2012
Arctic sea ice losses during 2011 were the second- greatest in the satellite record dating back to 1979, according to an official NSIDC report…. However, ice loss in recent years has been proceeding faster than the models predicted. EarthSky 2011 Headline: 2011 already costliest year for natural disasters.

NRT Water Sustainability Program Report II // NOV 2011 Information & advice to ensure the sustainable use of water by Canadas natural resource sectors Report I // JUNE 2010 Current state of water use by Canadas natural resource sectors & key issues
Water use forecasts – by sub sector 1.1% of total national use Unconventional oil and gas and agriculture biggest forecasted users.
Water intake intensity Natural resource sectors have steadily decoupled economic growth from their water intake & use.
Water, water everywhere… Misperception that Canada has an abundance of water Stresses on water resources already exist in some regions Economic growth & increasing demands for Canadas natural resources will mean more water will be needed Changes due to climate change will create uncertainty concerning temperature changes, rainfall, droughts and floods 24

Water & shale gas Water problem in shale is drawing a flood of capital (Houston Chronicle, Sept 19 th ) The need for huge volumes of water is a growing challenge for oil and gas companies working in shale formations, despite dramatic improvements in drilling speeds that have lowered other costs, energy executives said Wednesday. New shale gas licences at risk without common standards –study (London, Reuters, Sept 25 th ) "Public acceptance is paramount to the successful permitting and operation of shale gas projects," said Steinar Thon, associate director at DNV, who led the recommended practice study. DNV said it was crucial for companies to closely monitor fracking work and to communicate findings openly to the public, especially in regions where shale gas production is not an established industry. Shale gas well developers should also carefully handle the water and energy resources required for exploration, especially waste water, which has been a key concern in the public debate. New Brunswick researchers raise concerns about shale-gas fracking (Fredericton, Globe and Mail, Apr. 23 rd ) Researchers at the University of New Brunswick say shale-gas fracking should not proceed in the province unless there is an environmentally sound option for the disposal of waste water that is a by-product of the process. FRACTURED FUTURE: Scientific fact vs. public fears on water issues ( op-ed by Donald Siegal, CBC NB website, Nov 29, 2011) The public in New Brunswick should not fear that their water supplies and their air quality will be compromised because of hydro-fracking.
