As discussed earlier, I bought a RO filtration unit. Below you will find the pre and post analysis of my well water. My untreated water is more alkaline and has more sodium than it did three years ago; perhaps I should check it more frequently. We have, as many, been in considerable drought conditions. I don't know, if this is related. Regardless, the treated water should be fun to brew with.
