Total Trihalomethanes (TTHM)

The Public Utilities Department (PUD) delivers over 4.4 billion gallons of water to the Athens-Clarke County community.  We rely on source water pulled from the North and Middle Oconee Rivers and the Bear Creek Reservoir.  Your drinking water undergoes over 60,000 tests annually to ensure we provide you with the safe, high-quality drinking water you expect.  

The PUD has met the standards as set by the Environmental Protection Agency (EPA) and Georgia Environmental Protection Division (GA EPD) for all contaminants for thirteen consecutive years.  During the third quarter of 2021 (07/01/21 - 09/30/21) and the first quarter of 2022 (01/01/22 - 03/31/22), our water system exceeded the Disinfection Byproducts (DBPs) maximum contaminant level (MCL) for Total Trihalomethanes (TTHM).    

The violation posed no immediate health risk, and if it had, the PUD would have notified customers immediately.  The PUD has addressed the issue, and the TTHM results are again below the required levels.  Notification of the first quarter's above-average levels is mailed to customers, emailed to WaterSmart account holders, posted to social media, posted at the Water Business Office, placed as a notice in the local newspaper, and is available electronically.  

The PUD has taken several actions to address the elevated TTHMs.  The most recent results from the second quarter of 2022 return the PUD to compliance.  

We appreciate the trust you place in our water system and will continue to work 24/7 to provide you with excellent water services.
