Water is resilient and responds well to treatment. However, using water and abusing water by contaminating lakes, streams, and wells with toxic chemicals are two different things. To keep our drinking water safe, we need not only appropriate treatment, but also appropriate source protection. Most of our water has been touched by some type of human or animal activity. Therefore, it's always best to drink water that you know has been treated.
Bottled water is safer than tap water.
The safety of bottled water and tap water initially depends on the source of the water. Monitoring and source protection, treatment and testing ultimately determine the quality of the finished product. In the United States, the 1996 Reauthorization of the Safe Drinking Water Act will require that bottled water be monitored and tested in the same rigorous manner that tap water has been subject to for years. Using a home water treatment device will make tap water safer or healthier to drink. Additionally, all home treatment devices, regardless of the technologies they use, require regular maintenance.
