What Makes Santa Fe's Water Unique?
Local geology and source profile
Santa Fe, New Mexico — the state capital and oldest capital city in the United States — in Santa Fe County, draws its municipal water supply through the City of Santa Fe Utilities Division, sourcing from: Nichols and McClure Reservoirs on the Santa Fe River in the Santa Fe Canyon wilderness area of the Sangre de Cristo Mountains; the San Juan–Chama Project (transmountain diversion of the San Juan River from the Colorado Rockies into the Rio Grande via the Chama River) delivered to the Buckman Direct Diversion on the Rio Grande; and local Santa Fe Group groundwater wells. Water hardness in Santa Fe measures 80.5 mg/L — classified as moderately soft.
Santa Fe's moderately soft supply reflects the dominant influence of Santa Fe River canyon water from the Sangre de Cristo Mountains highlands. The Santa Fe River originates in the Sangre de Cristo Mountains Wilderness — draining the Precambrian Ortega Quartzite Formation and Vadito Group (ancient Proterozoic pelitic schist and quartzite) of the high mountains above Santa Fe at elevations above 12,000 feet. These ancient quartzites and schists — metamorphic equivalents of sand and shale — are essentially calcium-free. The San Juan–Chama Project contributes soft Colorado Rockies water. The Rio Grande–Buckman surface water contribution adds some mineral content but is managed and blended to produce the 80.5 mg/L finished result.
With hardness at 80.5 mg/L, Santa Fe residents experience minimal to moderate scale challenges. Faucet aerators and showerheads develop deposits slowly — bi-monthly cleaning with citric acid solution is sufficient. Dishwashers produce clean glassware. City of Santa Fe Utilities Division consistently delivers water meeting all New Mexico NMED and EPA Safe Drinking Water Act requirements.
Geology & Source: Mixed supply from Santa Fe River canyon reservoirs (Nichols and McClure Reservoirs on the Santa Fe River) and the San Juan–Chama Project transmountain water deliveries via the City of Santa Fe Utilities Division — the Santa Fe River watershed drains the Sangre de Cristo Mountains Precambrian quartzite and granite (Precambrian Ortega Formation, Vadito Group); very soft mountain supply at 80.5 mg/L in the Santa Fe National Forest zone.
