Arsenic can come out of CCA-treated wood. It can contaminate the soil directly below and next to the wood, or it can leave a residue on the wood’s surface.
Young children and people who work with wood are most likely to come in contact with CCA-treated wood.
Children could come in contact with arsenic while playing on or under structures made with CCA-treated wood. Their clothes and hands could pick up arsenic from the soil and the surface of the play structure.
People who spend a lot of time working with CCA-treated wood, including contractors and homeowners, could come in contact with high levels of arsenic, especially if they do not use protective gear.
If you have garden beds that are framed with CCA-treated wood, the Health Department recommends building new raised beds or garden borders with different materials.
