So, I've been putting together some preparedness supplies for a stormy day, and I've gotten to water purification. I've done some online research, but I'm not sure who to believe. I'm looking at providing enough water for an average-sized family.My geography provides some lake and pond water, storm run off's, a fair amount of rain, and access to wells that have organic material (not potable directly). I would be interested in a "base camp" style setup, and then some "short term" solutions as well. Any thoughts out there?
