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
and others on the list.  -Cynthia

>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
>an aerated lagoon.  The lagoon typically gets covered with duckweed by this
>time of the year, and we believe that the duckweed is what prevents algae
>growth.  Typically, with the duckweed, our lagoon effluent is very good.
>This year, however, the duckweed just hasn't taken hold.  We have very small
>patches of it, but not enough to make a difference.  There is significant
>algae, and our effluent is suffering.
>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
>with prodigious amounts of duckweed, so I'm wondering if I could take some
>of theirs to get ours going.
>I would greatly appreciate any help or advice you can give.
