Using less water not always environmentally preferable

Jacobs Consulting has released a study on the pluses and minuses of water recycling in the oil sands. Recycling can greatly reduce water use, but can also lead to more green house gas emissions, particularly when using a evaporation methods to recycle the water, which is necessary if there are high levels of dissolved solids.

Short story? Dealing with water is an environmental problem that involves trade-offs. In areas where plenty of water is available, like in northern Alberta at the moment, it may make more sense to use fresh water from rivers than salty water from aquifers because less greenhouse gases are ultimately released.


  1. green house gasses come from my bum, does that mean I need to pay a personal carbon tax?

    1. Yes, but the amount would be negligible unless you eat a lot of fruit. Also, I think you're posting on the wrong story, your insight would make more sense on this one:

  2. I'm sure sour gas comes from your bum too, so I imagine your insight would be more appropriate for the 'CNRL charged fro H2S release' article.
