## Water facts, as published
- No published hardness figure found for McAllen as of 2026-10-27.
- McAllen's water quality reports for 2019 through 2025 list no hardness figure. The 2025 report says secondary measures like this are not required to be reported.
- The nearest published measure we found is U.S. Geological Survey river data for the Rio Grande below Falcon Dam (1996-2000), which lists calcium and magnesium but no hardness value, so we show no figure.
- McAllen treats incoming river water with chlorine dioxide, then adds chlorine and ammonia to form chloramine that carries through the pipes.

- McAllen gets Rio Grande water released from Falcon and Amistad dams, moved by irrigation districts to the utility reservoirs and treated at its South and North plants.
