Are there any websites or mailing lists that describe the groups you have worked with that are doing work in NOLA?
There is a fellow in Florida who discoverd a type of fern that hyperaccumulates
arseniic in its tissues' I suppose this means that you can harvest them for HAZMAT disposal.
Maybe you can use this and get some stock donated by the nursery in Florida that sells them.
There are references to this on the web and I have a few somewhere in my archives.
At one time I regularly archived, before the Internet/WWWeb and the body of information it accesses got so huge,
newsworthy email and news articles plus files from gopher and ftp sites. Subsets of this collection cover
hyperaccumulation, bioremediation, aquaculture, composting, mycology and vermiculture. Most of this information
is old but some is timeless and may be of value to you. Look for the above words in the directory containing folders of
the same names.
You might want to consider getting donations of hundreds of tons of rock dust/siltation pond fines from rock quarries in
the NOLA area. If you could use a loader to mix some dust with the things you are trying to remediate or compost your
job would be made a lot easier. If I had the time and money I would go down to NOLA to spearhead a project to use rock
powders in this way just to prove that it would work. I would enjoy meeting those Bioremediators. Pond fines are usually
free for the hauling and you might find a contractor already working there who could haul them to your jobsites. What is
being done for sewage treatment? grey water? black water? composting humanure-lets.
Let me know if you want more ideas or info.
