Calgary scientists create mini-worlds to test water-treatment strategies
from Globe and Mail
Leland Jackson knows scum when he sees it — and he couldn't be happier to find it spreading throughout his $38.6 million state-of-the-art research facility on the banks of the Bow River. Scum is a key ingredient in Dr. Jackson's plan to plug a gaping hole in our knowledge of water pollution and accelerate the search for effective ways of treating it. The more faithfully he can generate scum that's just like the slimy film found in rivers and streams all around Canadian towns and cities where waste water is released, the better he can replicate what's going on in that water and gauge its downstream effects on people and the environment.
