Why Does San Antonio Have Such Hard Water?

July 12, 2012

Understanding San Antonio’s Water

You hear all the time that San Antonio and the Hill Country has some of the hardest water in the country. We talk about it often here at Kinetico San Antonio. And it’s often cited as the main reason why San Antonio water softeners are so important.

But do you know exactly why our area has such hard water?

The answer actually lies beneath us. Our water is hard because of the limestone in the Edwards Aquifer, which is our water source. In fact, the San Antonio Water System says hardness can even vary from one well to the next depending on porosity and density of the limestone below.

So there you have it. Question answered!

We're very glad we got this installed. The technician, Alberto, was very polite and thoroughly explained what he was doing and what we would need to do.

Alberto kept me informed on his arrival time. He was professional and exceeded my expectations concerning the install of the water filtration system. I also need to put a plug in for Tracy for her patience and skills at making things happen behind the scenes...a true unsung hero. They both deserve a raise!


I just had my system installed by Alberto and Jay, and I wanted to say that they rocked. Got it all in and gave me some instructions to follow, all while being determined to detail and professional. Thanks, fellas.
