The boil water advisory for north Rockdale that's been in place since Saturday has been lifted. The Georgia Environmental Protection Division rescinded on Tuesday a boil water advisory for Rockdale Water Resources (RWR) customers in the areas located north of and including Hi Roc Road.

Ga. Highway 138, which is where a water main broke Friday morning near the intersection of Sigman Road, is now open again to traffic. The water main line has been repaired.

It appears the water main was struck during construction-related underground drilling by workers for the Georgia Department of Transportation.

According to county officials, some follow up work on the road must be done at a later date, including thermo plastic striping the Department of Transportation requires.

About a quarter of RWR's approximate 24,000 customers in north Rockdale County were advised to boil all tap water prior to use for drinking, cooking or preparing baby food because the break caused low water pressure in that area.

RWR officials had to wait to get results back from water testing before the advisory could be lifted. The Georgia Environmental Protection Division must give permission to rescind the notice once it is determined that the microbiological quality of water in the RWR distribution system is safe for human consumption.

All tests came back negative for any elements, according to RWR officials, therefore making it acceptable for consumption.

When water pressure in the distribution system falls below the acceptable level, as specified by the Georgia Environmental Protection Division, a potential health hazard may result. The low pressure areas may experience backflow or back-siphonage of water of unknown quality into their water distribution system and ultimately their drinking water.

To protect against a potential health hazard, those RWR customers in that section of the county were advised to boil their water.

For any additional information, RWR personnel may be contacted at either 770-278-7400 or 770-278-7450.
