  • Do municipal water treatment systems take out all harmful substances from your water?
    - No. There are 35,000 pesticides containing 600 chemical compounds. Yet, at the time of this writing, municipal water systems are only required to test for six. Many of these chemicals are known to cause birth defects, nerve damage, sterility and cancer. A recent government study found that more than 25% of all large U.S. public water systems contain traces of one or more toxic substances. Public water systems do not test for the carcinogens and other dangerous chemicals that are being found. Water treatment plants are not always effective at removing harmful substances from your water supply. To ensure the protection of you, your family, and your children, it is recommended that you get a R.O. System to rid your water supply of all contaminants. However, if you cannot afford a R.O. System, look into Whole House Water Filters or other water filter types to rid your water of contaminants.
