So i have a large pond on a farm. If anything happens id like to be able to go down, get some water and purify for use in home.
Have well water now, the spring feeds the pond. I mention the farm thing bc of fertilizers and other potential runoff. We dont drink our home water rn but use it for brushing teeth and ice cubes. Its been tested and isnt bad but has some turbidity so its not aesthetically appealing.

Or, for a non-electric distiller: https://mypurewater.com/shop/portable-emergency-water-purification-system/. ["Limited supply" in case you're interested in one of these]
EDIT: We use an electric distiller for our well water (the water is very hard and Berkey's don't remove minerals); this one in particular: https://mypurewater.com/shop/mini-classic-ct-distiller/ -- it's been terrific for us; have used it for years.
