What Makes Palm Springs's Water Unique?
Local geology and source profile
Palm Springs, California, in Riverside County in the Coachella Valley at the foot of the San Jacinto Mountains — the iconic desert resort city known for mid-century modern architecture (the Palm Springs Modernism Tour), the Palm Springs Aerial Tramway (rising 8,516 feet from desert to alpine), a thriving LGBTQ+ community, Coachella Valley Music and Arts Festival (Indio), and one of the premier resort destinations in North America — draws its municipal water supply from the Coachella Valley Groundwater Basin via the Desert Water Agency (DWA). Water hardness in Palm Springs measures 121 mg/L — classified as moderately hard.
Palm Springs' moderate hardness — considerably softer than neighboring Rancho Mirage and Indian Wells — reflects the DWA well field characteristics in the upper Coachella Valley near Palm Springs. The Coachella Valley Groundwater Basin at Palm Springs is recharged from the Whitewater River spreading grounds (using State Water Project Colorado Aqueduct water import) and direct groundwater recharge from the San Jacinto Mountains (the San Jacinto Mountains Wilderness — predominantly Precambrian San Jacinto Anorthosite and Cretaceous Peninsular Ranges Batholith granodiorite, moderately calcareous Peninsular Ranges crystalline terrain). The DWA blend with State Water Project import produces the moderate 121 mg/L.
At 121 mg/L, Palm Springs residents and tourists encounter moderate scale accumulation in plumbing and appliances. Monthly cleaning with citric acid solution is practical maintenance. Desert Water Agency consistently delivers water meeting all California SWRCB and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Whitewater River Sub-basin (Coachella Valley Groundwater Basin) via the Desert Water Agency (DWA) — the Riverside County Coachella Valley (Quaternary alluvial fan deposits of San Jacinto Mountains granodiorite and Santa Rosa Mountains eroded granitic alluvium); moderately hard supply at 121 mg/L in Riverside County.
