Please reply directly to the sender as he's not subscribed to the APD. I
decided to forward this because bioremediation is of special interest to me

>I have a question about duckweed that I'm hoping you could help with.
>I work at an industrial facility, and our domestic wastewater is treated in

>This year, however, the duckweed just hasn't taken hold. We have very small

>I have a couple of questions:
>1. What are the conditions that promote duckweed growth?
>2. Is it possible to transplant duckweed? There are several ponds nearby by

>of theirs to get ours going.
>I would greatly appreciate any help or advice you can give.
