What Tuscaloosa's Water Means for Your Home

Tuscaloosa's water is moderately hard at 72 PPM. At this level, hard water is not a significant concern for most households. Scale buildup is minimal, and a water softener would provide little measurable benefit. If you are considering water treatment in Tuscaloosa, focus on contaminant filtration rather than softening.

Chlorine is present at 1.1 mg/L as a disinfectant residual, which is normal for municipal water systems.

For homeowners who want to understand the full picture, requesting your utility's annual Consumer Confidence Report provides neighborhood-level data.
