When most people think of toxic water pollution, they think of pipes spewing discolored, evil-smelling liquid into a river or lake. Indeed, the leading source of toxic water pollution now is toxic air emissions. The water pollution caused by these mercury air emissions alone have prompted public health agencies in forty states to issue formal advisories warning people to limit their consumption or avoid eating entirely certain species of fish caught from lakes and streams because of mercury contamination. These agencies have issued additional consumption warnings because of fish contaminated with dioxins, PCBs and other toxic pollutants. Even fish from remote areas, like Lake Superior, are contaminated.
