What's in NORTH CALDWELL BORO-0715's tap water
Top water quality concerns identified by the EPA and Environmental Working Group across the utility serving NORTH CALDWELL BORO-0715.
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.
Radon significantly above health guideline
Moderate concernRadon detected at 1821.67 pCi/L, 1214x above the EWG health guideline of 1.5 pCi/L.
Perfluorohexane sulfonate (PFHXS) significantly above health guideline
Moderate concernPerfluorohexane sulfonate (PFHXS) detected at 0.914 ppt, 914x above the EWG health guideline of 0.001 ppt.
Haloacetic acids (HAA9) significantly above health guideline
Moderate concernHaloacetic acids (HAA9) detected at 14.7 ppb, 245x above the EWG health guideline of 0.06 ppb.
Arsenic detected
Moderate concernArsenic detected at 0.625 ppb.
Recommended filters for NORTH CALDWELL BORO-0715
Filters matched to the specific contaminants in NORTH CALDWELL BORO-0715'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.
Reverse Osmosis
$249-$750Arsenic is most effectively removed by reverse osmosis. Some specialized adsorptive filters also work.
