Test results confirm water quality
San Antonio Water System has cleared the Lemonwood well site after follow up tests were negative for coliform or E. coli. SAWS disinfected the well Sunday, and then conducted tests to ensure that water in the area met all safe drinking water standards. The well is a vestige of the former BexarMet system and only feeds limited areas within Castle Hills.
Raw, or untreated water, is water from a well before disinfection with chlorine, and before entering the distribution system. All raw or untreated water is disinfected before entering the distribution system as finished water for customers.
There was no boil water notice in effect with the recent raw water tests. 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.
