Boil Water Advisory Lifted for Kent County Water Authority, City of Warwick Water - Potowomut section

The Rhode Island Department of Health (HEALTH) is lifting the boil water advisory that has been in place for customers of the Kent County Water Authority and for Potowomut customers of the City of Warwick Water since Sunday.

The boil water advisory is being lifted because samples from the Kent County Water Authority have been within acceptable standards for three consecutive days.

"The response to this incident demonstrates just how well Rhode Island's water systems and the public health system work," said Michael Fine, MD, Director of the Health. "At the first hint of a problem the Rhode Island Department of Health and the Kent County Water Authority responded to make sure that Rhode Islanders were not put in harm's way. Our state has some of the cleanest, best water in the country, and this type of collaboration is one reason why."

An investigation is still underway to determine why an initial test revealed the presence of coliform bacteria, which indicates the potential presence of disease-causing organisms. The tank that the positive sample was taken from will remain off-line while the investigation continues.

Affected customers should take certain precautions now that the advisory has been lifted.

Precautions for residential customers

Refrigerators with water dispensers/ice machines: Water dispensers/ice machines must be cleaned and sanitized before use. Follow the manufacturer's suggested sanitizing procedures in the operator's manual. Procedures should include the following minimum requirements:
