(My most recent absence can be attributed at least in part to the fact that I, along with most of Bozeman's Symphonic Choir, got up at an appallingly early hour on Saturday morning to catch the bus to Billings for a joint concert. We acquitted ourselves honorably (three standing ovations, though one being for Bach's 4th Brandenburg Concerto which features not a note for singers, it's hard to take credit for all three. I'll give it a try, though: we were eloquent even in silence? No? Anyway, after the reception some of us sang all the way home, arriving at those homes about nineteen hours after we'd left them. Such excursions require a day or two to catch one's breath.)
Last week Jen in Maryland left the following comment on my January post “Compost vs. Arsenic: And the winner is–compost!” about dealing with arsenic in garden soil:
As a gardening novice, I placed a small veggie garden next to an old telephone pole in my backyard. It then dawned on me that maybe the soil could be contaminated with whatever they treated the pole with. The house is 60 years old, so I don’t know, but now I’m tempted to give up, for fear of contaminating my family. Advice?
The stuff we are talking about here is the copper chromate arsenate (CCA) that was used as a wood preservative from the 1930s on. By the 70s it had became the outdoor wood-treatment of choice across the United States until concerns that matched Jen's led to its being banned by the EPA, save for a few rare exceptions, in 2003.
