Researchers: Treated wood poses long-term threat
Arsenic from treated lumber used in decks, utility poles and fences will likely leach into the environment for decades to come, possibly threatening groundwater, according to two research papers published online Wednesday.
Researchers from the University of Miami, the University of Florida and Florida International University examined arsenic leaching from chromated copper arsenate, or CCA-treated wood, from a real deck as well as from simulated landfills.
