Raw Water Well Sample Tests Positive for E. coli Bacteria in Far West SA

During standard water quality sampling, a raw, untreated water sample from a well located near Tippecanoe street indicated the presence of E. coli bacteria. The well came to SAWS as a part of the former BexarMet system.

SAWS shut down the well immediately based on the test result and will disinfect it before putting it into further use.

The well is located in far west San Antonio, between Ingram Rd. and Loop 1604, south of Potranco Rd. and north of Marbach Rd.

Raw, or untreated water, is water from a well before disinfection, and before entering the system providing water to customers. All raw or untreated water is disinfected before entering the distribution system as finished water for customers.

All test samples taken from SAWS water system for December have been clear of any evidence of E. coli.

“We are constantly testing San Antonio’s water to ensure it is high quality. Finding this result and responding to it demonstrates the safeguards in SAWS system are working the way they should to ensure safe drinking water is flowing to your home,” said Donovan Burton, VP Water Resources & Governmental Relations.

Please note this is NOT a Boil Water notice. You do not need to take additional measures prior to consumption. Under the Groundwater Rule established by the U.S. Environmental Protection Agency and the Texas Commission on Environmental Quality, SAWS is required to provide public notice if a water well tests positive for E. coli or fecal bacteria.
