Can you tell me more about filtered water as opposed to tap water?

The quality of tap water can vary depending upon where you live and whether the water is provided from a municipal site or you have your own spring or well. Contamination can occur not only from the water source but also from sources closer to home. For example, the quality of your water can be affected by your type of plumbing (whether you have copper lined pipes, lead solder containing plumbing, etc.), whether you use a well, and whether there is contamination from agricultural chemicals. If you are curious about the quality of your water, you may want to get it tested. In general, it would be best to filter city water before consumption. With rural (well) water, the decision about filtering is usually best made on a well-by-well basis.

If you are concerned about the quality of your tap water, you may want to investigate getting a water filter. In general, the best water filters involve blocks of carbon (rather than granulated carbon) and are often combined with reverse osmosis filters. The under-sink types of filters are typically more effective than the type that attach at the faucet. I recommend carbon block or reverse osmosis filters over distilled water because I believe that too many desirable minerals are lost during the process of distillation. Another option that may be available in your area is water filtration systems in supermarkets. Many natural foods supermarkets offer good quality water filtration systems where you can refill your own jugs. For some this is a convenient option, yet for others having a home filtration system is more convenient.

Whatever option you use for guaranteeing high quality water, you also need to make sure that you consume enough water during the course of the day. Water is usually best consumed between meals if you are drinking a sizable amount (8 ounces or more). As for intake goals, the National Academy of Sciences recommends (in its Dietary Reference Intake (DRI) recommendations) about 13 cups of water each day for men and 9 cups for women.
