Is ARLINGTON tap water safe to drink?
CITY OF ARLINGTON delivers tap water that earns a grade of D (61/100) from TapWaterSafety.org — a below-average rating, with multiple concerns including pfas contamination.
The utility serves 413,955 residents in ARLINGTON, drawing from surface water. 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 14 contaminants in this water above EWG's health-based guidelines, including: Arsenic, Haloacetic acids (HAA9), Bromochloroacetic acid, Total trihalomethanes (TTHMs), Haloacetic acids (HAA5), Bromodichloromethane, Dibromoacetic acid, Dibromochloromethane, Bromate, Dichloroacetic acid, Chloroform, Perfluorooctane sulfonate (PFOS), Nitrate, Bromoform. 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.

Recommended water filters for ARLINGTON
Filters matched to the specific contaminants in this 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.
