PFAS in Huntsville Utilities water (Alabama)

Huntsville Utilities is a large public water system serving more than 10,000 people in Alabama (ZIP codes 35801, 35802, 35803, 35804, 35805, 35806, …). EPA UCMR 5 monitoring (2023–2025) detected 6 PFAS compounds in its water, the highest being PFBA at 11 ppt. This includes PFOA at 4.7 ppt and PFOS at 9 ppt. This page shows every detected level and the certified filters that reduce PFAS.

What was detected

Each figure is the highest single detected level recorded for that compound — not an average.

For context, the U.S. EPA has set a federal reference level of 4 parts per trillion for PFOA and for PFOS; it is shown beside those compounds above purely as a reference point.

How to reduce PFAS in this water

Your only flagged issue is PFAS / PFOA / PFOS, which harms you through what you drink — not through bathing or showering. A certified under-sink reverse-osmosis system (~$300–$600) is the correct, certified way to remove it. A $1,500–$4,000 whole-house system would be overkill here and still wouldn’t be the certified method for these contaminants.

Certified point-of-use filters (the practical, certified fix)

If you want PFAS reduced at every tap (optional)

Point-of-use reverse osmosis above is the default, certified answer for PFAS. If you specifically want reduction at every tap, these are the whole-house units with a genuine third-party certification for PFOA/PFOS — an optional add-on, not a necessity.
