Definitely looking for alternatives is one of the strategies, but certainly there's also reuse and recycling, utilizing it in other areas to minimize the amount of fresh water we use.
Shell, for example, has a very innovative project where they utilize waste water from the city of Dawson Creek as some of their source water for their hydraulic fracturing operations.
So absolutely we are looking for alternative means to the use of fresh water.
You mentioned the disposal. I will just mention very quickly that there are very strict regulations that govern the integrity of disposal wells in Canada. In fact, in Alberta and British Columbia there is no surface disposal of produced water; it's only allowed underground, under strict regulations.
