Water filtration in Buda
Buda's water is mostly surface water from Canyon Lake and the Guadalupe River, treated at the San Marcos plant operated by GBRA. The rest comes from the city's Edwards Aquifer wells.
According to the 2025 report, it's roughly 70 percent surface water and 30 percent groundwater.

Free chlorine, not chloramine
Buda disinfects with free chlorine, averaging about 1.0 mg/L in 2025. Chlorine is easier to filter than chloramine, so standard carbon filtration works well for taste and smell.
Hardness and other notes
Buda's report doesn't publish a hardness number. Edwards Aquifer groundwater is typically hard, and nearby Kyle reports very hard water, so it's worth testing at your tap.
The city does not add fluoride. In federal UCMR5 testing it reported PFBA at 16 to 17 ppt, and PFOS was not detected.
