Heavy metals are difficult to remove from the water, but having said that, I would still have a Berkey System on hand for use with another source of water.

would this be the same issue for iron
oldest son lives up on the iron range in Mn. and the water is loaded with iron
the well test safe for bacteria and is working fine
also the locals deal with what is called septic cysts and was wondering if is a water issue
at this point they are drinking bottled water
but if SHTF that wont last long
one thought is catching rain water and filtering with a berkey
what are your thoughts
