Speaking of water, we live in the Washington, DC area. Our pipes are so old that we have a breach at least once a month. Then you are told to boil your water at least 10 minutes for drinking water. Of course, by this time, all the bottled water is gone from the stores. There are five of us in this house, and my granddaughter who is 12. We gave up and bought a Big Berkey unit. It is so wonderful. You pour any kind of water in the top and it filters out everything. Chlorine and all. To test it you add a few drops of red food coloring and the water comes out clear and tastes so good.
I use it for everything now. We had a rain barrel but the county told us we couldn't keep it. I loved to wash my hair in rainwater. We put it thru the Berkey until we had to ditch it. We are warned that at some point we will be hit inDC.
