Is Pressure Treated wood safe?

As of January 1, 2004, wood treated with CCA (chromated copper arsenate), has been phased out for consumer use. ACQ (alkaline copper quat) and CA (copper azole) are the new formulations used for treating wood against termite damage and rot. The EPA has approved all treatment methods for safe usage in residential applications. Other popular pressure-treated wood alternatives include cedar and tropical hardwoods.
