Colorado Springs Water Hardness at a Glance
Colorado Springs, CO — Water Hardness Data
Why Is Colorado Springs Water Moderately Hard?
Colorado Springs draws from Pike's Peak snowmelt and the Arkansas River system — sources that flow through the Front Range granite but also interact with some sedimentary rock as they descend from the mountains. The result is water softer than the limestone-aquifer cities of the Southwest but slightly harder than Denver, which draws more exclusively from granitic mountain sources.
The USGS classifies Colorado Springs's 6–10 gpg as Moderately Hard.

Advantages of Soft Water in Colorado Springs
At 6–10 gpg, Colorado Springs's moderately hard water comes with real household benefits:
- Appliance longevity: Water heaters, dishwashers, and washing machines last significantly longer without scale buildup. No descaling required.
- Soap efficiency: Moderately soft water lathers easily — you'll use less soap, shampoo, and detergent for the same result.
- Skin and hair: No mineral film on skin after showering. Hair tends to feel softer and cleaner than in hard-water cities.
- Minimal fixture maintenance: Little to no white scale on showerheads, faucets, or kettles. A quick vinegar wipe every few months is sufficient.
Water Treatment Options for Colorado Springs
At 6–10 gpg, a whole-home softener is optional. The EPA Consumer Confidence Report program requires Colorado Springs Utilities to publish annual contaminant data. If you're concerned about PFAS, chlorine, or disinfection byproducts, a filter addresses those independently of hardness.
