Hi Janet,
Monday, May 08, 2000, 11:15:47 AM, you posted what appears to be a
forwarded request:
JG> Here is a question concerning planting trees and grasses in
JG> Delaware.
It's a waste water issue concerning phytoremediation.
JG> Does anyone have any advice for the person?
JG> Thanks,

It would have been good to include "the person"'s email address.

It's not clear that the person is looking for direct remediation;
uptake and tranformation of designated waste products.

There are other factors involved (i.e. soil, temperature, cloud
cover) and neither the goal nor the mechanism is clearly stated.
I was going to suggest that the person contact vita.org. They have
people who deal with the things I assumed she or he was looking. But
I don't know if VITA will get involved with something for Delaware
(they helped me get together what I needed to evaluate a wate water
issue in Jalisco some time back) and I'm not sure whether what's
being looked for is viable.
A plant that takes up a lot water is wanted? Water lilies have been
used for this (waste water phytoremediation) and there are other
water loving succulent plants that thrive in damp earth, like
watercress, nastursiums.
