Comparing in-home and bottled drinking water quality: regulated and emerging contaminants in rural Central Appalachia
Science
3 Sep 2025 | J Water Health
PFAS were present at very low levels in some in-home, spring, and bottled water, measured by LC-MS/MS with reporting limits down to 0.015 ppt, bottled water showed total PFAS up to 2.354 ppt with no individual PFAS exceeding the April 2024 EPA MCLs, and only one tap sample contained GenX at 0.136 ppt.
