About Guadalupe County

Guadalupe County at the southern edge of the Texas Hill Country transitions from limestone karst terrain to Blackland Prairie clay, creating diverse septic system requirements depending on location within the county. The Edwards and Carrizo-Wilcox aquifers provide well water, and the county's rapid growth between San Antonio and San Marcos has increased scrutiny of on-site sewage facilities to protect groundwater recharge zones.
