Sometimes we may need to draw upon that knowledge to figure out where tomorrows food comes from and how to prepare it. I applaud you for retaining that ability. At least your Grandchildren won't go hungry.
# guerilla gardening is a skill to teach. Maybe a walk down to the creek with your bucket reaps several pounds of produce growing in the wild.... take it home...eat it.... natural goodness..... Yum!!
Well I would look up stream 1st. Ya never know what your neighbors have been up too. A case in point. I would never eat fish or produce out of Animas river after that EPA spill that they never cleaned up. And certainly no fish from the Pacific given the nuclear disaster in Japan. I would eat food down stream from an confined animal facility as long as there was 4ft between the animal pen and the water. Why? Because I saw the studies in Oregon that showed that the water from feed pen is clean as long as you have a 4 ft perimeter of soil be teen the pens and the water. The soil apparently filters better than we thought
It turns out even sand is ok after 4 ft. Weird I know but I saw all the tests. I would never have guessed that 4 ft was all you needed.
Interesting... I'd like to read that study... That would mean you could drop a well within a short distance from a stream and be relatively safe.
i see you grasp the genius of this study, it disproved alot of the EPA's objections to winter feed lots along the Snake River. I'll see if i can find it and pm you the link.
