Please note: This page is a plain-language overview and is not the official report. Values shown are the federal or state limits, not measured results — refer to your utility's published Consumer Confidence Report for current measured values. CCRs reflect the utility's system; conditions at your own tap can differ due to household plumbing. Book a free in-home test for tap-level data.
Key Contaminants Detected
Total Trihalomethanes (TTHMs)
DetectedSee current CCRLimit80 ppb (EPA MCL)
A regulated disinfection byproduct formed when chlorine reacts with organic matter in surface water. GSWSA publishes its measured levels annually.
Haloacetic Acids (HAA5)
DetectedSee current CCRLimit60 ppb (EPA MCL)
A regulated disinfection byproduct associated with chlorine disinfection of organic-rich source water.
PFAS
DetectedSee current CCRLimit4.0 ppt each (EPA MCL, PFOA/PFOS)
EPA's 2024 rule is in effect: initial monitoring is due by 2027 and compliance by 2029. In May 2026 EPA proposed allowing extensions to 2031 and rescinding the limits for four other PFAS; neither proposal is final.

What an In-Home Test Adds to Your CCR
A Consumer Confidence Report reflects water quality within the utility's system. ClearFlow's free in-home test measures conditions at your own faucet, such as hardness, iron, manganese, pH and dissolved solids — values that can differ from system-wide results because of your home's plumbing.
