Brian, The Canadian standards, in all frankness, are better than the US's because their process is more honest and less politically manipulated. While not perfect, I would accept Canadian national standards for heavy metals, etc, as being a good guideline for community gardeners.
That said, here are some local contacts that may be helpful for you in your knowledge search: I. First, to keep you from re-inventing the wheel, I'd contact your local Utah State agricultural extension: <A HREF="http://extension.usu.edu/cooperative/index.cfm/cid.246/">Utah Ag Extension</A> The Salt Lake contact numbers are: Contact Information: 2001 South State Street #1200 Salt Lake City, UT 84190-2350 801-468-3170 County Website: <A HREF="http://www.usuextension.slco.org/">www.usuextension.slco.org</A> Information via Utah Reach <A HREF="http://utahreach.org/salt%20lake/">http://utahreach.org/salt%20lake/</A> II. The director of Utah's Organic Agriculture Program is listed below. I believe specific queries on soil testing and standards are best made to these folks in your area. If you have never been involved in soil testing, there is a learning curve, and talking to reputable experts is well worth your time.
