dragonrider, I remember a local news story from my area about a development built on an old battery recycling facility. They were able to unearth pieces of battery cases and the EPA made them all leave while the clean-up took place. PPM of lead and acid were way too high so it pays a person to research the area before buying but in this case I think these were mid-income homes. It sounded like it was an underhanded deal by the contracter, developer , and the EPA for my state to me. Its not suprising since our current gov. is sort of "not a legal minded person". I think he's more worried about his libedo than his job but I guess thats the in thing to do these days.
I think your post was a good one and certainly proves a big point, poverty is the most formidable enemy of the environment. I was interested in the
GIS portion especially. I've tried to educate people on its use for also regulating industrial hemp production as tobacco is on its way out but the
old southern baptist, which are based in the cotton growing states who don't want hemp as competition, refuse to credit it usefulness.
