Socorro Water Hardness & Quality Report (2026)

Socorro, Texas, in El Paso County — a major El Paso County border community (Socorro is in the lower El Paso Valley — a significant border community adjacent to El Paso and Juarez, Mexico, one of the oldest continuously inhabited communities in Texas; the Socorro Mission, established in 1680, is one of the oldest Spanish missions in the United States), a primarily Hispanic-American and Mexican-American community (Socorro and the lower El Paso Valley are among the most heavily Hispanic communities in Texas — the majority of residents are of Mexican origin or descent, and the community has strong cultural and family ties across the US-Mexico border), home of the historic Socorro Mission (one of the three Spanish colonial Ysleta–Socorro–San Elizario Missions — a National Historic Landmark in the lower El Paso Valley), and a rapidly growing El Paso County border suburban community — draws its municipal water supply from the Rio Grande and Hueco Bolson via El Paso Water Utilities. Water hardness in Socorro measures 352 mg/L — classified as extremely hard.

Socorro's extremely hard supply reflects the west Texas Chihuahuan Desert Rio Grande Valley's highly calcareous and evaporite geology. The Hueco Bolson aquifer and Rio Grande at Socorro–El Paso County draw from: the Permian Hueco Bolson (calcareous and evaporite-influenced basin aquifer); the Rio Grande calcareous evaporite and Chihuahuan Desert carbonate dissolved mineral supply. EPWU treatment reduces from raw values but cannot eliminate the extremely hard 352 mg/L.

At 352 mg/L, Socorro residents face severe hard water challenges. Water softeners and appliance protection are essential. El Paso Water Utilities consistently delivers water meeting all Texas TCEQ and EPA Safe Drinking Water Act requirements.
