GREENE COUNTY, Va. (CBS19 NEWS) -- Some Greene County residents are now under a boil water advisory.

According to a release, this notice affects consumers of the Mountain Lakes Water Company, specifically people who live in the Twin Lakes and Green Mountain Lakes communities.

Greene County, Mountain Lakes Water Company and the Blue Ridge Health District say residents should use either boiled tap water or bottled water as a safety precaution.

This is due to a service interruption and loss of water pressure that began on Nov. 11, and officials say E. coli bacteria may have infiltrated the distribution system.

The Virginia Department of Health was notified about the water pressure issues on Monday.

People who are exposed to E. coli may experience diarrhea, cramps, nausea, headaches or other symptoms.

This bacterium may pose a greater risk for infants, young children, the elderly and people with compromised immune systems.

Residents should not drink the tap water without boiling it first until further notice.

Boiled or bottled water should be used for drinking, beverage or food preparation, making ice, bathing, and brushing teeth.

Tap water should be brought to a rolling boil and let boil for at least one minute before being allowed to cool for use.
