" water quality (testing for pollutants from runoff?)"

Considering sewage treatment facilities,when actually working, are minimal at best, you can imagine how well they function without power.

A group was coordinating divers to recover materials out of CGB.

Water shoes at minimum and I'd be a bit more cautious when swells are up and moving a lot of sand.

Just ran across this on FB a few minutes after posting. "There is a huge environmental issue on the beaches with a lot of debris under a layer of sand."
