Is BROKEN ARROW tap water safe to drink?
BROKEN ARROW MUNICIPAL AUTHORITY delivers tap water that earns a grade of D (59/100) from TapWaterSafety.org — a below-average rating, with multiple concerns including pfas contamination.
The utility serves 116,330 residents in BROKEN ARROW, 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 16 contaminants in this water above EWG's health-based guidelines, including: Perfluorooctane sulfonate (PFOS), Perfluorohexane sulfonate (PFHXS), Haloacetic acids (HAA9), Total trihalomethanes (TTHMs), Bromodichloromethane, Haloacetic acids (HAA5), Dibromochloromethane, Dibromoacetic acid, Dichloroacetic acid, Trichloroacetic acid, Chloroform, Radium, combined (-226 and -228), Chromium (hexavalent), Bromoform, Atrazine, Chlorate. 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.

Moderate concernPerfluorohexane sulfonate (PFHXS) detected at 3.8 ppt, 3800x above the EWG health guideline of 0.001 ppt.
Haloacetic acids (HAA9) significantly above health guideline
Moderate concernHaloacetic acids (HAA9) detected at 36.5 ppb, 608x above the EWG health guideline of 0.06 ppb.
Total trihalomethanes (TTHMs) significantly above health guideline
Moderate concernTotal trihalomethanes (TTHMs) detected at 47.8 ppb, 319x above the EWG health guideline of 0.15 ppb.
