What Makes Apple Valley's Water Unique?
Local geology and source profile
Apple Valley, California, in the Victor Valley of San Bernardino County (the High Desert), draws its municipal water supply from the Mojave River Basin groundwater via the Apple Valley Ranchos Water Company (a regulated investor-owned utility serving Apple Valley) and from Mojave Water Agency (MWA) imported water blending, accessing the Victor Valley sub-basin alluvial aquifer in the Apple Valley–Victorville area. Water hardness in Apple Valley measures 149.5 mg/L — classified as moderately hard.
Apple Valley's moderate hardness reflects the Victor Valley Mojave Basin groundwater character. The Mojave River flows from the San Bernardino Mountains (Cretaceous granodiorite and Precambrian gneiss of the San Bernardino Mountains) northward across the High Desert, recharging the Mojave River Alluvial Aquifer (Quaternary and Pliocene alluvial fan deposits). As the Mojave River crosses from the crystalline San Bernardino Mountains into the Mojave Desert basin floor, it encounters Tertiary and Quaternary alluvial fan deposits derived from the Mojave Desert mountain ranges (mixed lithology including calcareous materials). The Victor Valley alluvium has accumulated moderate dissolved minerals from desert concentration and calcareous caliche-cemented sediments in the alluvial fill, producing the 149.5 mg/L moderate hardness.
At 149.5 mg/L, Apple Valley residents encounter moderate scale accumulation. Faucet aerators and showerheads develop deposits after several months — monthly cleaning with citric acid solution is practical maintenance. Apple Valley Ranchos Water Company and Mojave Water Agency consistently deliver water meeting all California SWRCB and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Mojave River Basin and the Victor Valley sub-basin via the Apple Valley Ranchos Water Company and Mojave Water Agency (MWA) — the Mojave Desert Basin Tertiary–Quaternary alluvial fill over the Precambrian basement, recharged by the Mojave River and State Water Project (SWP) imports; moderately hard supply at 149.5 mg/L in San Bernardino County High Desert.
