"EVERETT -- For decades, the Kimberly-Clark plant provided countless jobs in Snohomish County and paper products to millions of people.

Now that it's closed, the plant is leaving behind another, not-so-positive legacy.

Dioxins -- toxic substances thought to cause cancer in humans -- have been found in the waterway next to the plant at a level 15 times higher than what the state considers safe. The dioxins in sediment under the water are a result of the bleaching process in making paper.

On land, some petroleum contamination has been found at the 66-acre plant site and under what is now a parking lot south of the plant. Oil companies used parts of the current plant site and the parking lot for petroleum storage and distribution during much of the 20th century."
