Reading about the hazard of selenium fumes in glass smelters, was reminded about this example in our own backyard.

The new report, written by a Bullseye contractor based in Tigard called the Bridgewater Group, said most of the pollution was found near the contaminated dry well at the site's southwest corner. In groundwater at that location, it found cadmium, another toxic metal, at a level that was 26 times the EPA's drinking water standard. It also found elevated levels of arsenic, cadmium, copper, lead, selenium, silver and zinc.
