EPA calls for phase-out of copper arsenate treated wood. (News Flash!).

The lumber industry has recently announced that they plan to phase out the use of arsenic-treated wood, seeking alternative preservatives. By 2004, CCA-treated wood will no longer be available for residential use. Chromated copper arsenate (CCA) has been used to preserve wood since the 1940 s to protect it from dry rot, fungi, mold, termites and other pests. In some aspects, this preservative seems to benefit the environment, as wood treated with it lasts ten to twenty times longer than untreated wood. Currently, about seventy-five million square feet of it can be found in residential areas. It is often used in the construction of decks, picnic tables, play-structures, fencing, patios, and walkways.

Arsenic is known to be carcinogenic, so many critics believe that CCA should be banned entirely. The EPA maintains that there has been no proof that CCA represents any serious health risk. They feel already existing structures need not be replaced. However, they also admit that more research must be done before a real risk assessment can be made. According to several scientific studies, arsenic frequently leaks out and can contaminate the surface of the wood as well as its surroundings. Tests run on the soil from several Florida playgrounds indicated arsenic levels many times over the state s suggested limit. City officials have agreed to tear the structures down, but many have decided to simply close the parks until the EPA gives its verdict. Furthermore, sawing or burning the wood can lead to serious health complications by releasing toxic gases into the air. Food should not be placed directly on CCA treated wood, and children should always wash their hands after playing outdoors. Because this phase-out affects only residential uses of CCA, carpenters and contractors who are already at high risk will continue to have contact with the wood.
