Is LUBBOCK tap water safe to drink?
LUBBOCK PUBLIC WATER SYSTEM delivers tap water that earns a grade of D (59/100) from TapWaterSafety.org — a below-average rating, with multiple concerns including arsenic significantly above health guideline.
The utility serves 275,041 residents in LUBBOCK, 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 arsenic significantly above health guideline.
Public testing data identifies 17 contaminants in this water above EWG's health-based guidelines, including: Arsenic, Haloacetic acids (HAA9), Dibromoacetic acid, Bromochloroacetic acid, Total trihalomethanes (TTHMs), Haloacetic acids (HAA5), Dibromochloromethane, Chromium (hexavalent), Bromodichloromethane, Bromoform, Nitrate and nitrite, Dichloroacetic acid, Nitrate, Chlorite, Uranium, Trichloroacetic acid, 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.
