A leak in Castel Heights Saturday morning prompted orders in the Town of Pomfret and the Village of Fredonia.
Health officials suggest boiling water for one minute and then letting it cool before you drink it.
Contaminated water can cause a plethora of illnesses such as diarrhea, vomiting, abdominal cramps and nausea.
