Medford Water Commission's 2025 analyses list two sources: Big Butte Springs at 37.7 mg/L (2.2 gpg) and the Duff water treatment plant at 26.5 mg/L (1.5 gpg). The page shows the median of 32.1 mg/L (1.9 gpg). That is soft water, so scale is minor and a softener adds little for hardness.

USGS classes: soft 0–60, moderately hard 61–120, hard 121–180, very hard >180 mg/L.
