Living in the Hill Country’s a great many benefits but it also means that you do need a Water Filtration or Water Softner System. Here is why:
San Antonio’s main water service is Edwards Aquifer. Most underground water sources will have a high mineral content in solution (dissolved solids). These dissolved solids are picked up as water runs through limestone and ground strata on the way to the aquifer. On the national average 10 grains per gallon is considered extremely hard. The average for SAWS and Bexar Met water is 22 grains per gallon or 22 g.p.g.
Other minerals, such as iron, manganese, sulfur and tannins can be in local well water, and these minerals are sized on parts per million or p.p.m.
