Our data show that any contamination will not be limited to one lake, but will over time extend down the length of the network of rivers. We had thought of these lakes as isolated biological laboratories. Now we are going to have to think again. |
The lakes are like a set of beads on a string, where the lakes are the beads connected by a string, or river of water. |
What this paper shows is that not only could you contaminate a lake, you could contaminate the whole drainage system. |
