The Boerne City Council meeting on August 12, 2025, focused on ongoing water quality issues, particularly concerning disinfection byproducts (DBPs) in the city's water supply. Director Mann addressed the council, providing an update on the situation and the city's efforts to manage it.

Mann explained that the city has been grappling with two main water quality challenges. The first issue involves DBPs, which occur when chlorine used for disinfection interacts with organic materials in the water. This problem has persisted as the city has shifted from groundwater to lake water sources. As the reliance on groundwater has decreased, the concentration of these byproducts has increased, leading to higher levels than allowed.

In July of the previous year, the city attempted to conserve groundwater, which resulted in an insufficient supply and subsequently elevated DBP levels during testing. Mann noted that this spike in concentration has impacted the city's water quality reports for three out of the last four quarters. However, he reassured the council that the situation has improved since then, with the city now treating water to meet state standards.

The discussion highlighted the city's commitment to addressing water quality concerns and ensuring safe drinking water for residents. Further updates on the situation are expected as the city continues to monitor and manage its water supply effectively.
