water purification
I am trying to find the name and address of a man in the north east U.S.
who has setup a working water purification system using plants.He had a
large green house filled with various vessels containing plants and water
animals and microbes and was able to completely clean polluted water. He
was featured in a television program dealing with world water problems. The
program was with David Suzuki and aired last spring. Thanks

Perhaps the place to start would be getting an analysis for heavy metals.
I would expect them to be concentrated in the ash. Whether or not they're
present probably depends on the type of wood and where it grew.
And, as you probably know, addition of ashes to already alkaline soil
(most desert soils) is a mistake. Here in the middle of the Mojave
desert, we put a lot of effort into reducing soil pH.
