| What is the source of my drinking water? | |||||||||
| The sources of the Liberty Tree water supply are two wells located between Washington Drive and Lincoln Drive in Raymond, NH. BRW # 1 is 12 feet east-north-east of the pump station and BRW # 2 in 8 feet south-south-east of the pump station. Treatment consists of chlorine addition to kill bacteria and softening to reduce water hardness. | |||||||||
