The Petroleum Technology Alliance Canada, for example, recently stated that its “largest concern ” in the oil sands was water use and reuse because “bitumen production can be much more fresh water intensive than other oil production operations. ” 5 A 2006 Alberta report (Investing In Our Future) noted that “over the long term the Athabasca River may not have sufficient flows to meet the needs of all the planned mining operations and |
