What's in CLINT's tap water
Top water quality concerns identified by the EPA and Environmental Working Group across the utility serving CLINT.
PFAS contamination
Severe concernPerfluorooctane sulfonate (PFOS)* detected. PFAS are persistent chemicals linked to cancer and immune effects with no known safe exposure threshold.
Arsenic* significantly above health guideline
Moderate concernArsenic* detected at 4.07 ppb, 1018x above the EWG health guideline of 0.004 ppb.
Haloacetic acids (HAA9) significantly above health guideline
Moderate concernHaloacetic acids (HAA9) detected at 26.8 ppb, 446x above the EWG health guideline of 0.06 ppb.
Total trihalomethanes (TTHMs) significantly above health guideline
Moderate concernTotal trihalomethanes (TTHMs) detected at 24.3 ppb, 162x above the EWG health guideline of 0.15 ppb.
Recommended filters for CLINT
Filters matched to the specific contaminants in CLINT'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.
Reverse Osmosis
$249-$750Arsenic is most effectively removed by reverse osmosis. Some specialized adsorptive filters also work.
Carbon block (NSF/ANSI 42 + 53)
$40-$750Activated carbon is highly effective for disinfection byproducts like TTHM and HAA5.
