the lake air i mentioned was having to do with all the industy factories in the great lake area.i should of made that clear. would some type of sediment type filter get the water to a state of being able to wash with. and are there any know alges that would /could be use to purify the water to be able to drink it, instead of a chlorine or bleach. those are some crude ideas, but would they be worth doing to save run time on the well pump.
