San Marcos is served by City of San Marcos Water Department, which draws from San Marcos Springs and Edwards Aquifer production wells. Local water tests in the range of 12 grains per gallon, based on the most recent utility averages.
San Marcos draws from San Marcos Springs, one of the largest spring systems in the Edwards Aquifer, at the border of Hays and Comal counties. Spring discharge water is among the softer outputs of the Edwards system, typically reading around 12 grains per gallon. While that is lower than the San Antonio metro average, it still falls well above the soft threshold. Texas State University students and residents moving from outside Texas are often unaware of local water hardness until they see the effects on coffee makers and faucets.
Common local water concerns
- Hard water minerals (approximately 12 grains per gallon, San Marcos Springs source)
- Total dissolved solids
