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.
