The Coal Grove Water System is advising residents to boil their water for three minutes before using after a water break on Wednesday caused a loss of pressure in the distribution system.

The pressure loss may cause backpressure, back siphonage or a net movement of water from outside the pipe to the inside through cracks, breaks or joints in the distribution system that are common in all water systems.

Such a system failure carries with it a high potential that total coliform or other disease-causing organisms could enter the distribution system.

Residents should not drink the water without boiling it first. Bring all water to a rolling boil for at least three minutes, and let it cool before using, or use bottled water.

Boiled or bottled water should be used for drinking, making ice, brushing teeth, washing dishes and preparing food until further notice. Boiling kills bacteria and other organisms in the water. All stored water, drink or ice made recently from this supply shall be discarded.

The areas of Coal Grove affected include Marion Pike from Melvins Center to the Lane Street intersection, High Street (Giovanni’s side), Washington Street, Three Oaks area, Compliment Street, Rowe Street, Lane Street (park side), Argonne Street, Calvary Street, Hamilton Street and Gunn Street.
