"...Washington Department of Ecology is planning the next phase of arsenic and lead cleanup associated with a century of operations at the former Asarco smelter in Ruston.... These properties are within a 200 square-mile geographic “service area” that includes the most highly contaminated portions of the Tacoma Smelter Plume....."
"...Ecology will clean up ...areas with results that average above those cleanup levels or that have a reading of 40 parts ppm arsenic or 500 ppm for lead in one location...."

There was an article in the El Paso Times, that stated the plume effected everything and everyone in a 50 mile radius - 50 miles in each direction, that's 200 miles all together. It all depended on which way the wind blew.
