Are PFAS chemicals in your drinking water?
On June 6, 2025, we completed Adopt-a-Stream monitoring at an added site located at the SR 155 Bridge over Walnut Creek, immediately downstream of the "City of McDonough Filter Intake". The City of McDonough 2024 Water Quality Report identifies the "John H. Fargason Reservoir" on Walnut Creek as its primary drinking water source.
The water collection at SR 155/Walnut Creek was submitted to an independent Certified Laboratory for analysis of PFAS (per-and polyfluoroalkyl substances).
PFAS have been linked to various health problems, including: Liver damage, Thyroid disease, Obesity, Fertility issues, Cancer, Interference with vaccine effectiveness. Their persistence in the environment (aka forever chemicals) poses long-term risks to ecosystems and wildlife.
The U.S. EPA has established drinking water standards for several PFAS at 4 parts per trillion (ppt). However the long term goal (a non-enforceable health-based goal) is set at zero.
The regulations do not take affect until 2031 and only apply to drinking water. PFAS bioaccumulate in organisms such as the fish we eat and the food we consume.
We detected PFAS at 2.8 ppt at the SR 155/Walnut Creek Bridge. Remember the health goal is zero PFAS.
Contact your water supplier and ask how PFAS are currently treated and tested for presence, in your tap water.
Home PFAS test kits are available.
