Ever wonder why your skin feels different after a shower here compared to other cities? It's not your imagination.
San Antonio's water comes primarily from the Edwards Aquifer, and on its way to your tap, it travels through miles of limestone, picking up calcium and magnesium along the way. That's what makes our water some of the hardest in the state.
It's not unsafe. It's just mineral-heavy, and that mineral content is exactly what's behind the spots on your dishes, the film on your shower doors, and the extra strain on your appliances.
Know your water, know your options.
