Before Z After

I do not live in Zihuatanejo I am only a visitor. But if someone was dredging in my bay, I would want to know the arsenic levels. There has to be a plan here? You cannot dredge and pile the crap in the same area.

(Rob has a translator on the top of the page) but one (translated) quote is "He explained that temporarily, in a Tarquina, or kind of pot, to be installed in the grounds of Las Salinas, the sludge will be deposited with a hose.
