I agree with the other posts, then there is the aspect of
Pytoremediation where all plant material will break down organic
contaminats in the ground and surface water.

I find the propensity to dredge all waterways a bad thing to for the

as for evaporative loss in irrigaton and potable aquiducts arid climate
governments would do good to enclose them. 

Here in wisconsin it is an old practice to plant a willow down slope
from a septic system.
