Is GEORGETOWN tap water safe to drink?
CITY OF GEORGETOWN delivers tap water that earns a grade of D (55/100) from TapWaterSafety.org — a below-average rating, with multiple concerns including pfas contamination.
The utility serves 191,639 residents in GEORGETOWN, 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 19 contaminants in this water above EWG's health-based guidelines, including: Perfluorohexane sulfonate (PFHXS), Haloacetic acids (HAA9), Bromochloroacetic acid, Total trihalomethanes (TTHMs), Dibromoacetic acid, Bromodichloromethane, Dibromochloromethane, Haloacetic acids (HAA5), Dichloroacetic acid, 1,2,3-Trichloropropane, Bromoform, Trichloroacetic acid, Chloroform, Chromium (hexavalent), Nitrate, Perfluorooctanoic acid (PFOA), Perfluorooctane sulfonate (PFOS), Chlorate, 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.
