Long story short, over the fence of my backyard is an old canal that in the 1930's carried waste water from kennecott coppers lead mine plant. The old canal I guess has high concentrations of arsnic, that as of yesterday they started to dig it all out. I'm not the kind to get overly freaked out by something like this, but in the same breath I want to be as educated as I can about it. From what I've read the main/only concern is not to injest/eat the arsnic. Having said that my wife is about to plant a fairly large garden in our back yard. Bad idea??? If I was smarter I'd put up a link to the article, you can google "magna canal project" and see/read about it. Prolly no one cares but me but I thought there may be someone out there with some mining or chemestry background that could let me know their thoughts on this. Thanks and sorry for the long read, sincerly your toxic waste boater. Kreg.
