Alamo Heights' groundwater tests positive for E. coli

SAN ANTONIO — Groundwater at a well in Alamo Heights has tested positive for E. coli bacteria, but the city's drinking water has not been affected.

All groundwater is treated before entering the city's distribution system. None of the water sampled from the city's distribution system tested positive for the bacteria. Residents do not need to treat or boil their water before drinking it, the city said.

The Alamo Heights Water System removed the well with the positive sample, located on the 6100 block of Broadway, from service.

The city is investigating the source.
