Safe Drinking Water Act

The Safe Drinking Water Act provides the rules that govern drinking water operations.  These operations are regulated in Maine by the State's Drinking Water Program.

Your drinking water can come from up to 5 different wells.  Brookside, Triangle and South wells are located on the west side of the river and Riverside South and Riverside North are located on the east side of the river.  

Your drinking water is thoroughly tested in accordance with Maine law and the Safe Drinking Water Act.

To help prevent tooth decay, well water is treated with 0.7 milligrams per liter (0.7 parts per million, ppm) of sodium fluoride.  Sodium hypochlorite (the active ingredient in laundry bleach) is also added to disinfect water from the wells and protect the distribution system from organic contaminants and other microorganisms.  A sequestering agent (polyorthophosphate) is added to reduce lead and copper levels at the tap and reduce both iron and calcium levels in the distribution system.

The wells are naturally high in calcium.  Calcium hardness levels range from approximately 130 milligrams per liter (130 ppm) to 200 milligrams per liter.  Water hardness is characterized as being "hard" to "very hard".  While this level is perfectly safe, some customers have expressed concern about white spots on dishes or sinks.  The white spotting is just dry calcium and is not harmful to your health.

Your drinking water is overseen by Maine licensed water treatment operators.  Water quality is also continually monitored by computers.  Alarms are triggered if water quality characteristics fall out of allowable ranges.
