| What is the
source of my drinking water? |
|
|
|
|
|
|
|
|
| The source for the Valley Field water supply is two bedrock
wells and a pump station. Well # 1 is
located 274 feet west of the pump house.
Well # 3 is located 605 feet northwest of the pump house. Treatment consists of manganese green sand
filtration to remove iron and manganese, aeration to remove radon, sodium
hydroxide to adjust the pH, and chlorine addition to kill bacteria. |
