City finds E. coli in well


A City of San Marcos well tested positive for E. coli during a recent water sample. Notification of the test results were received Thursday.

The sample was taken from raw untreated water from a city well that supplies only 1.5 percent of the city’s total system supply.

The city immediately discontinued the well from active service. Water personnel are working to restore water quality to the well.

All raw water is disinfected before distribution as potable water. No E. coli bacteria have been detected in the distribution system samples.

“This is a required regulatory notice under the ground water treatment rule,” said Tom Taggart, the city’s director of public services. “Bacteria are commonly present in the environment and raw water supply sources. This is why raw water is treated to drinking water standards to ensure public health.”

The following actions are being taken by the city:

• The well that tested positive has been discontinued from active service.
• Water employees have begun flushing the well to provide fresh water to the well.
• Limited disinfection of the well may be utilized if flushing is unsuccessful.
• Further bacterial samples will be collected to confirm the results.

The city is working with the Texas Commission on Environmental Quality (TCEQ) to insure that all regulatory requirements are adhered to and public health is protected at all times.

Residents may call the city’s public services department at (512) 393-8010 for more information.
