CCA chemical treated wood. It has been banned from retail sales but has some kind of exemption for coastal areas - which is nuts. http://www.origen.net/ccawood.html http://www.epa.gov/oppad001/reregistration/cca/ http://www.atsdr.cdc.gov/csem/arsenic/routes.html http://www.ecologycenter.org/factsheets ... _wood.html http://www.beyondpesticides.org/photost ... eek_40.htm |

Howard, Is there a product in the organic program that we can use to treat our lumber that will preserve the wood? |

Thanks for the info Joe! I didn't think there was an organic method of wood treatment. I was sort of leaning towards using untreated timbers for building some raised beds, and letting them rot over time. |
