David,
I noticed your request for information on the dioxin-l list. You may
be interested in a paper that we presented at the recent IFCS meeting
in Japan on alternative destruction technologies. It is avaliable on
the IFCS website at http://www.who.int/ifcs/isg3/d98-17b
Here in Sydney, the NSW Government have recently committed to
remediating the contaminated sediments of Homebush Bay - adjacent to
the Sydney 2000 Olympic site. The sediments contain dioxins (up to 550
ppb ITEQ) and a range of other organochlorines including DDT, DDE, DDD
(at above 1000 ppm!!), which resulted from dumping by a Union Carbide
2,4,5 T factory. The commitment is to remove and treat the sediments
using non-incineration destruction technology. A number of treatment
methods have been proposed including variants of Base Catalysed
Dechlorination (BCD), gas phase hydrogenation, and catalyic
hydrogenation (all discussed in above paper).
Other useful resources are the USEPA Haz Waste Cleanup website at
http://clu-in.org
Environment Australia have produced an overview of alt-detox
technologies which is also availavble on the web at
http://www.environment.gov.au/portfolio/epg/environet/swtt/contents.ht

On the issue of sediment remediation, the Great Lakes National
Program Office have a number of useful documents available at:

To most people solutions mean finding the answers.
But to chemists solutions are things that are still all mixed up.
