Why Is San Antonio Water So Hard?

Detail shot of a drop of water emerging from a faucetHomeowners in the San Antonio, Texas, area deal with problems caused by some of the hardest water in the nation, and the source of their hard water woes lies beneath their feet. Most San Antonio residents get their tap water from the Edwards Aquifer, an underground system of porous rocks that’s dominated by limestone. When rainwater saturates the ground, it permeates the soil and then percolates through layers of limestone until it reaches an opening that can be tapped by a well. The limestone layers help cleanse the water as it flows through this natural underground system, but the water also picks up high concentrations of dissolved minerals along the way. The minerals that are chiefly responsible for hard water are dissolved calcium and magnesium.

Is Hard Water Safe to Drink?

The mineral concentrations that cause hard water are considered safe for drinking and bathing for humans and their pets. Municipal water supplies are treated to meet standards established in the federal Safe Drinking Water Act, and therefore do not address water hardness issues.

However, that doesn’t mean that San Antonio homeowners should simply resign themselves to dealing with the many problems caused by hard water, including:

  • Rough, itchy skin and brittle, lackluster hair that often result from showering in hard water
  • Unsightly mineral deposits on freshly washed glassware that makes it appear dirty and unappealing
  • Limescale buildup in plumbing and water-using appliances that can lead to the need for premature repairs or replacement
