HANOVER COUNTY, Va. (WRIC) -- Hanover County's first water test results on Friday show no harmful contaminants, however, parts of the county are still under a boil water advisory. On Friday, Jan. 10, Hanover County announced that no harmful contaminants were detected in the county's initial water-quality testing. "If the second round of testing confirms the water is safe to consume, the County anticipates the Virginia Department of Health will lift the boil water advisory for areas east of I-95 on Saturday afternoon," the county said in its statement. The boil water advisory, issued on Tuesday for parts of Hanover County, was the result of water service disruptions caused by a power outage at the City of Richmond’s water treatment facility, which supplies water to Hanover, Henrico and Chesterfield counties. According to the county, residents east of Interstate 95 should continue boiling water for drinking and cooking until the advisory is lifted. Residents living west of I-95 do not need to boil water. The county advises that water should be brought to a rolling boil for one minute and cooled before use. Hanover County is continuing to provide free water to residents at the following locations: Friday, Jan. 10 until 6 p.m. Bottled water distribution Cold Harbor Elementary School, located at 6740 Cold Harbor Rd.
