Following months of failing to meet minimum treatment techniques for its water supply, the city of Pflugerville issued updated information Jan. 13 indicating another issue.
A computer programming error in December potentially affected around 80,000 gallons of water, which is less than 2% of the city’s daily water usage, according to the Jan. 13 news release. During a routine test Dec. 24, a membrane integrity test incorrectly categorized a substandard water filtration membrane as functioning within acceptable levels. That membrane remained in production for approximately 2 1/2 hours, per the release.
“The city’s top priority is the health and safety of its citizens, therefore for additional redundancy, city staff has implemented the requirement that water operators confirm manually that all testing functions meet TCEQ [Texas Commission on Environmental Quality] standards regardless of the computer display,” City Manager Sereniah Breland said in the release.
After the issue was discovered, staff found the turbidity level, which is the level of clarity of the water, was compliant with the TCEQ, state and federal requirements, the release states.
