The most significant water quality concerns are: PFAS contamination; Arsenic* significantly above health guideline; Haloacetic acids (HAA9) significantly above health guideline; Total trihalomethanes (TTHMs) significantly above health guideline. For questions, the utility can be reached at 915-791-4480.
Is CLINT tap water safe to drink?
LOWER VALLEY WATER DISTRICT delivers tap water that earns a grade of F (50/100) from TapWaterSafety.org — a poor rating, with significant contamination concerns and/or recent violations.
The utility serves 59,049 residents in CLINT, drawing from surface water (purchased). Despite being legal under US EPA standards, this water would fail the European Union's Drinking Water Directive, primarily due to pfas contamination.
Public testing data identifies 18 contaminants in this water above EWG's health-based guidelines, including: Arsenic*, Haloacetic acids (HAA9), Total trihalomethanes (TTHMs), Bromodichloromethane, Bromochloroacetic acid, Dibromochloromethane, Chromium (hexavalent), Dibromoacetic acid, Haloacetic acids (HAA5), Bromate*, Bromoform, Nitrate, Chloroform, Dichloroacetic acid, Trichloroacetic acid, Radium, combined (-226 and -228)*, Uranium*, Nitrate and nitrite*. For most residents, a properly certified home filter at the kitchen tap is the most cost-effective way to reduce exposure to whatever's in your water. See our filter recommendations below, matched specifically to this utility's contaminant profile.

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 water filters for CLINT
Filters matched to the specific contaminants in this 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.
Carbon filter certified for VOCs (NSF/ANSI 53)
$180-$599Activated carbon is effective for disinfection byproducts. Look for NSF/ANSI 53 VOC reduction.
