The boil water advisory issued on Monday, Dec. 3 has been lifted.
Samples examined by the Georgia Environmental Protection Division (EPD) confirmed there is no contamination in the public water system, according to the Atlanta Department of Watershed Management. Water can be used for all purposes safely.
The problems were caused by control issues at the Hemphill Pump Station. Around 10 a.m. Monday crews were performing routine maintenance on the Hemphill Water Treatment Plant flow meters. Their work tripped a process control alarm, which signaled the pumps to shut off, causing outages and pressure issues in the area, according to department materials.
The boil water advisory was issued because water pressure fell below 20 pounds per square inch (psi). According to the department of watershed management, normal pressure is between 30 and 80 psi. The advisory was issued in accordance with the Georgia Environmental Protection Division (EPD) guidelines, however, the department described it as a measure taken “out of an abundance of caution.”
