Water should be your very first consideration when planning for your long-term survival. If you're like me and have limited experience with non-municipal water systems, you may have some learning to do. Have your water tested to determine the kinds of filtration and other treatment needed - your health and the health of your house systems will thank you. Your testing results will be specific to your location. Do your research and consult professionals if you need guidance- not all filtration systems are equal or appropriate for your situation.
