Look at the Berkey purifiers. I have one black two filter (double 5 gal bucket) kit on the shelf ready to use. I got it
here for $75. For the water out of my well, I'll pre filter it with a coffee filter then run it through the Berkey. My well water is not the best drinking water (we use it for irrigating), but my house is on community water. It is a small water district with three different wells and a large tank. I'm setting up to store 100 gallons in two barrels and ten gallons in 2.5 gallon jugs. This will be short term. The Berkey filters are for long term solution for unprocessed water from my well, or the seasonal watershed creek by my house.
My brother currently lives in Mexico on the mainland. He uses this Berkey kit for all of his consumed water. The water there is very chlorinated to the point of it smelling like a public pool. And it is not safe to drink without purifying. After the Berkey, it's good to go.
