Recent headlines have sparked confusion regarding a mandated advisory from the Environmental Protection Division (EPD) concerning a reported “spill” in Lake Allatoona. The Cobb Water System’s Northwest Water Reclamation Facility, permitted to treat up to 12 million gallons of wastewater daily, regularly releases treated water into Lake Allatoona, subject to routine testing.

On Thursday, June 27, 2024, routine tests indicated that a component of the released water exceeded specifications, prompting a public notice. Subsequent tests on Sunday, June 30, 2024, and Monday, July 1, 2024, confirmed similar readings. Immediate measures were enacted, and the disinfected wastewater poses no threat to drinking water supplies, with no cleanup necessary.

Strict adherence to EPD regulations guides Cobb County Water System’s actions. Ongoing investigations into the cause of these readings include considerations of possible contaminants introduced into the wastewater system. The release of treated wastewater into Lake Allatoona is part of the system’s permitted operations and occurs daily.
