The source of the Whispering Winds water supply is the Dame, Ducharme, and Weinstein wells, located in Litchfield.  A supplementary source of water is the Pennichuck Pond System during peak demand periods.  Treatment for the three well supplies consist of chlorine for disinfection, pH adjustment for corrosion control, and phosphate addition for corrosion control and iron and manganese sequestration.

Radon is a radioactive gas that you can't see, taste or smell.  It can move up through the ground and into a home through cracks and holes in the foundation.  Radon can also get into indoor air when released from tap water from showering, washing dishes, and other household activities.  It is a known human carcinogen.  Breathing radon can lead to lung cancer.  Drinking water containing radon may cause an increased risk of stomach cancer.  Presently EPA is reviewing a standard for radon in water.
