| Nitrate in drinking water at levels above 10 ppm is a health risk for infants of less than six months of age. High nitrate levels in drinking water can cause blue baby syndrome, Nitrate levels may rise quickly for short periods of time because of rainfall or agricultural activity. If you are caring for an infant you should ask advice from your health care provider. | |||||||||

| What is the source of my drinking water? | |||||||||
| The source of the Pinehaven water supply are four point wells located 30 feet north of the pump house. The pump house is located on Pleasant Drive in Londonderry, NH. Treatment consists of chlorine addition to kill bacteria, aeration to remove radon from the water, and sodium hydroxide to adjust pH to aid in corrosion control. | |||||||||
