City clears well of E. coli

STAFF REPORT

A repeat analysis of raw water from a City of San Marcos water well tested clear of E. coli bacteria Tuesday.

The well will return to service Wednesday.

The well was shut down on Feb. 26 after the bacteria was found in a raw water sample. City water utility workers flushed the well on Friday and again on Monday to provide fresh water and to restore water quality.

The additional sample drawn Monday from the Spring Lake No. 1 well was tested by the Edwards Aquifer Research and Data Center Laboratory at Texas State, which found no E. coli in the raw water.

No bacteria were found in the city’s water distribution system, which supplies potable water to the community. The city’s water utility disinfects all water before it is sent into the distribution system.

The original samples were taken of raw, untreated water from a well that supplies 1.5 percent of the total system supply. Most of the city’s treated water comes from surface water.

“Escherichia coli” are bacteria commonly found in the intestines of warm blooded animals. Some E. Coli strains can cause serious gastrointestinal illnesses in humans if consumed.

The city said its chlorine treatment effectively disinfects and eliminates all potential bacterial contaminants.

The city has worked with the Texas Commission on Environmental Quality (TCEQ) to insure all regulatory requirements are followed and public health is protected at all times, said Tom Taggart, the city’s director of public services.

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