Is SAN ANGELO tap water safe to drink?
CITY OF SAN ANGELO delivers tap water that earns a grade of F (51/100) from TapWaterSafety.org — a poor rating, with significant contamination concerns and/or recent violations.
The utility serves 105,229 residents in SAN ANGELO, 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 perfluorohexane sulfonate (pfhxs) significantly above health guideline.
Public testing data identifies 15 contaminants in this water above EWG's health-based guidelines, including: Perfluorohexane sulfonate (PFHXS), Haloacetic acids (HAA9), Dibromoacetic acid, Total trihalomethanes (TTHMs), Bromochloroacetic acid, Arsenic, Haloacetic acids (HAA5), Dibromochloromethane, Bromodichloromethane, Bromoform, Dichloroacetic acid, Trichloroacetic acid, Chloroform, Uranium, Nitrate. 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.
