| Arsenic: While your drinking water meets EPA’s standard for arsenic, it does contain low levels of arsenic. EPA’s standard balances the current understanding of arsenic’s possible health effects against the cost of removing arsenic from drinking water. EPA continues to research the health effects of low levels of arsenic which is a mineral know to cause cancer in humans at high concentrations and is linked to other health effects such as skin damage and circulatory problems. | |||||||||

| What is the source of my drinking water? | |||||||||
| The source of the Stone Sled Farm water supply is two wells located in the Stone Sled Farm development in Bow, NH. Well # 1 is located 85 feet east of the pump house and well # 2 is located 30 feet east of the pump house. Treatment consists of ion exchange to reduce iron and manganese levels, aeration to remove radon, phosphates to sequester iron and manganese, and arsenic removal. | |||||||||
