Cimarron Hills Water Hardness & Quality Report (2026)

Cimarron Hills, Colorado, in El Paso County — an unincorporated El Paso County community adjacent to Colorado Springs and Fountain in the central Colorado Front Range — receives its municipal water from Colorado Springs Utilities, drawing from the Fountain Creek watershed and local reservoirs (El Paso County) through the Colorado Springs distribution system.

The moderately hard 124 mg/L hardness and TDS of 279 mg/L are somewhat harder than the high-mountain Colorado Springs supplies (Canon City: 77 mg/L), reflecting the Palmer Divide and piedmont calcareous formations at the lower Colorado Springs elevation. The Fountain Creek at El Paso County drains the Front Range — Precambrian Pikes Peak Granite (insoluble), and the Palmer Divide at lower elevations — Cretaceous Pierre Shale (calcareous — the primary hardness source in the east Colorado Springs piedmont). The Cretaceous calcareous shale input produces the moderately hard east Colorado Springs supply.

At 124 mg/L, Cimarron Hills' water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 4.4 ppt warrants a certified drinking water filter — Peterson Space Force Base and Fort Carson (El Paso County — AFFF, the dominant Colorado Springs military PFAS sources), and the Front Range military corridor contribute to Cimarron Hills' readings.
