What's in LAKEWOOD's tap water
Top water quality concerns identified by the EPA and Environmental Working Group across the utility serving LAKEWOOD.
PFAS contamination
Severe concernPerfluorooctanoic acid (PFOA), Total PFOS and PFOA detected. PFAS are persistent chemicals linked to cancer and immune effects with no known safe exposure threshold.
Total PFOS and PFOA significantly above health guideline
Moderate concernTotal PFOS and PFOA detected at 5.35 ppt, 764x above the EWG health guideline of 0.007 ppt.
Perfluorohexane sulfonate (PFHXS) significantly above health guideline
Moderate concernPerfluorohexane sulfonate (PFHXS) detected at 0.72 ppt, 720x above the EWG health guideline of 0.001 ppt.
Arsenic significantly above health guideline
Moderate concernArsenic detected at 1.15 ppb, 288x above the EWG health guideline of 0.004 ppb.

Recommended filters for LAKEWOOD
Filters matched to the specific contaminants in LAKEWOOD'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.
Reverse osmosis certified for arsenic (NSF/ANSI 58)
$429-$599Reverse osmosis certified under NSF/ANSI 58 for arsenic is the most reliable home option.
