DIOXIN STUDY NEEDED FOR DIXICO

Continuing thoughts on the Dixico incinerator:
When organic solvents are burned at low temperatures, and burned incompletely, dioxin and furans are produced. These are known and undisputed carcinogens. The Dixico incinerator was documented repeatedly as burning at too low temperature. One document reads temp was "400."
Back in the 80s, dioxin was not reported by industry-including Dixico; although the dioxin problem is practically synonymous with plastics and PVC, which Dixico dealt with in tons.
Dioxin degrades to half in 15 years, years which have past, UNLESS it is below ground and mixed and bound with sediment in soil as at the bottom of a lake, stream, river, or creek.
I am thinking a dioxin study of Dixico is in order. And...a water study also.
If Dixico were to be studied for CERCLA, many enlightening studies would be done.
But will that happen?
Isn't it easier to let bygones be bygones? It would be if ... so many neighbors had not died.
If two creeks weren't involved, if the chemicals used had been less dangerous and in smaller amounts....So many ifs and so many buts...
What ever happened to enforcing the intent of environmental law in a timely manner-or at all?
