What's in CONCORD's tap water
Top water quality concerns identified by the EPA and Environmental Working Group across the utility serving CONCORD.
PFAS contamination
Severe concernPerfluorooctane sulfonate (PFOS), 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 60.1 ppb, 1002x above the EWG health guideline of 0.06 ppb.
Perfluorohexane sulfonate (PFHXS) significantly above health guideline
Moderate concernPerfluorohexane sulfonate (PFHXS) detected at 0.49 ppt, 490x above the EWG health guideline of 0.001 ppt.
Haloacetic acids (HAA5) significantly above health guideline
Moderate concernHaloacetic acids (HAA5) detected at 38.7 ppb, 387x above the EWG health guideline of 0.1 ppb.
Recommended filters for CONCORD
Filters matched to the specific contaminants in CONCORD's water supply.
Reverse Osmosis or NSF P473 certified carbon
$80-$750Activated carbon and RO are the only technologies proven to remove PFAS at certified levels.
Carbon block (NSF/ANSI 42 + 53)
$40-$750Activated carbon is highly effective for disinfection byproducts like TTHM and HAA5.
