Re: agent orange's fingerprints
Thanks Jon, I'll look into it. I am aware of some of that story, but Greenpeace
no doubt has agood write-up.
Yep, we do have an astounding amount of contamination. The 40 miles of Kanawha
River below Monsanto's plant has had an advisory on it since 1986 for people to
be aware not to eat the fish. Still, the WV DNR maintains public fishing areas
on the river which are not posted with any warnings. The DNR has nice pamphlets
to hand out to the public telling them of all the good waters in the state in
which to fish, but nothing regarding which streams have fish advisories.
Compare this to other states. Arkansas, for example, has a "quarantine" on
fishing for the Arkansas River due to drainage from Vertac via Bayou Meto. I
worry that my state's officials are more concerned with selling fishing licenses
than protecting the fishermen.
