What's in ALEXANDRIA CITY's tap water
Top water quality concerns identified by the EPA and Environmental Working Group across the utility serving ALEXANDRIA CITY.
PFAS contamination
Severe concernPerfluorooctanoic acid (PFOA)*, Perfluorooctane sulfonate (PFOS)* 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 16.0 ppb, 266x above the EWG health guideline of 0.06 ppb.
Total trihalomethanes (TTHMs) significantly above health guideline
Moderate concernTotal trihalomethanes (TTHMs) detected at 19.0 ppb, 126x above the EWG health guideline of 0.15 ppb.
Haloacetic acids (HAA5) significantly above health guideline
Moderate concernHaloacetic acids (HAA5) detected at 11.3 ppb, 113x above the EWG health guideline of 0.1 ppb.

Recommended filters for ALEXANDRIA CITY
Filters matched to the specific contaminants in ALEXANDRIA CITY'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.
