Three bedrock wells supply the Badger Hill water system.  Well # 1 is located 199' north west of the pump house, Well # 2 is located 30' north of the pump house, and Well # 3 is located 590' south west of the pump house.  Water treatment consist of iron and manganese removal, chlorine for disinfection, and bag filters to remove sediment.

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.
