Water Quality

Water Quality Reports
We’re once again proud to present our annual water quality report covering all testing performed between January 1 and December 31, 2023. Over the years, we have dedicated ourselves to producing drinking water that meets all state and federal standards. We continually strive to adopt new methods for delivering the best-quality drinking water to you.


Tennessee American Water Co. PFAS FAQ

Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals found in various household products, including nonstick cookware (e.g., Teflon™), stain repellents (e.g., Scotchgard™), and waterproofing materials (e.g., GORE-TEX™). They are also utilized in industrial processes such as firefighting foams and electronics manufacturing. Thousands of PFAS chemicals exist, known for their persistence in the environment. Notable PFAS include perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), which were phased out in the United States and replaced by substances like hexafluoropropylene oxide-dimer acid (GenX) and perfluorobutane sulfonic acid (PFBS).

Signal Mountain Water Utility and Tennessee American Water have conducted voluntary sampling to better understand the presence of certain PFAS in drinking water sources. This initiative prepares us for the forthcoming U.S. EPA drinking water standards for six PFAS chemicals: PFOA (4 ppt), PFOS (4 ppt), and a group standard for GenX, PFBS, PFNA, and PFHxS using a Hazard Index of 1. For more details on the proposed standards, please visit EPA's PFAS page. Additionally, in 2024, Signal Mountain Water Utility and Tennessee American Water Citico Plant will test drinking water for 29 PFAS chemicals as part of the U.S. EPA's Unregulated Contaminant Monitoring Rule (UCMR) program, which gathers data on currently unregulated contaminants to inform potential new regulations.

Signal Mountain Water Utility is committed to leading in PFAS research and regulation, a rapidly evolving area in the drinking water field. We have invested in independent research and collaborate with experts to understand PFAS occurrence and are actively exploring treatment technologies to effectively remove PFAS from drinking water.
