Researchers at Oregon State University have confirmed decks built with today’s pressure-treated preserved wood products cause no environmental harm from preservative chemicals leaching from the wood and into rainwater or surrounding soil. The researchers collected runoff and soil samples the first and fourth years after construction of a deck built with wood pressure treated with Copper Azole (CA-C), the preservative used to treat the preserved wood sold for decks and other residential projects.
