I envision that run-off is most easily captured from a paved lot. It could be
put through some type of filter trap to remove oil/gasoline/brake fluid, etc.,
then perhaps put into a biofilter of some type.
If the lot is not paved, has anyone had experience with using a membrane
beneath gravel to keep run-off water from sinking into the ground, presumably
carrying the pollutant with it?
If I'm on the wrong track altogether, please suggest what is the best way to
think about this problem. I'm very interested in solutions that people have
actually built (it's fine for this question to spark a long theoretical thread,
but I'm looking for installations!)
Thanks
Marc
