Effects at 364.5 PPM Hardness

At 364.5 ppm, effects are significant: heavy white scale buildup on pipes and fixtures, very dry skin and hair, stiff and scratchy laundry, and reduced water heater efficiency by 25–40%. Expect frequent cleaning of mineral deposits and noticeably higher energy bills from scale-insulated heating elements.

Is Amarillo Water Safe to Drink?

Yes. Hard water at 364.5 ppm in Amarillo is safe to drink. The calcium and magnesium that make water hard are actually essential minerals your body needs daily. The World Health Organization confirms there are no health-based guidelines for water hardness.

You may notice a slightly mineral or chalky taste at this hardness level. A drinking water filter (pitcher-style carbon filter or under-sink reverse osmosis system) can improve taste if desired, though the water remains perfectly safe to drink unfiltered.

Your Water vs National Average
