The whole San Francisco Bay and CA Central Delta that feeds it is polluted
from mercury from way back in the CA gold rush. Not quite as bad, but one
shouldn't eat more than two fish (or waterfowl or crawdads, etc) per month.
That's too scary for me.

There's hardly a river in the US that isn't grossly polluted by something.
I'm only 60 miles from the pristine origins of the Arkansas River here in
CO. Guess what is right at the beginning of the very first snow trickle
runoff. An ex toxic waste site, the Climax Mine, a molydedenum mine that's
been polluting for over a century. It's been pretty much cleaned up, now,
and a fish and game biologist swears there's no real threat of of tainted
fish, but....

You pays your money and takes yer chances.
