Is GARLAND tap water safe to drink?
CITY OF GARLAND delivers tap water that earns a grade of C (67/100) from TapWaterSafety.org — an average rating, with several contaminants above health guidelines but generally compliant with US legal limits.
The utility serves 248,822 residents in GARLAND, drawing from surface water (purchased). Despite being legal under US EPA standards, this water would fail the European Union's Drinking Water Directive, primarily due to haloacetic acids (haa9) significantly above health guideline.
Public testing data identifies 18 contaminants in this water above EWG's health-based guidelines, including: Haloacetic acids (HAA9), Bromochloroacetic acid, Total trihalomethanes (TTHMs), Haloacetic acids (HAA5), Bromodichloromethane, Dibromoacetic acid, Dibromochloromethane, Dichloroacetic acid, Trichloroacetic acid, Chloroform, Radium, combined (-226 and -228)*, Bromoform, Chromium (hexavalent), Chlorate, Nitrate*, Atrazine*, Chlorite*, Bromate*. 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.
