What's in LEXINGTON's tap water
Top water quality concerns identified by the EPA and Environmental Working Group across the utility serving LEXINGTON.
PFAS contamination
Severe concernPerfluorononanoic acid (PFNA), Perfluorooctanoic acid (PFOA) detected. PFAS are persistent chemicals linked to cancer and immune effects with no known safe exposure threshold.
Haloacetic acids (HAA9) significantly above health guideline
Moderate concernHaloacetic acids (HAA9) detected at 35.1 ppb, 586x above the EWG health guideline of 0.06 ppb.
Perfluorohexane sulfonate (PFHXS) significantly above health guideline
Moderate concernPerfluorohexane sulfonate (PFHXS) detected at 0.42 ppt, 420x above the EWG health guideline of 0.001 ppt.
Total trihalomethanes (TTHMs) significantly above health guideline
Moderate concernTotal trihalomethanes (TTHMs) detected at 38.4 ppb, 256x above the EWG health guideline of 0.15 ppb.

Recommended filters for LEXINGTON
Filters matched to the specific contaminants in LEXINGTON's water supply.
Filter certified for PFOA/PFOS (NSF/ANSI 53 or 58)
$180-$750Reverse osmosis and some carbon block filters reduce PFAS. Look for certification to NSF/ANSI 53 or 58 for PFOA/PFOS.
Carbon filter certified for VOCs (NSF/ANSI 53)
$180-$599Activated carbon is effective for disinfection byproducts. Look for NSF/ANSI 53 VOC reduction.
