Is Tap Water Safe to Drink in Huntsville?
Yes, tap water in Huntsville is safe to drink. Huntsville Utilities treats Tennessee River water drawn from Wheeler Reservoir along with local groundwater, and the finished supply meets all EPA standards. The area's notable PFAS problems affected systems downstream, not Huntsville's intakes.
Water Source
Huntsville Utilities draws primarily from the Tennessee River's Wheeler Reservoir at two treatment plants, supplemented by groundwater from springs and wells at the base of the region's karst terrain.
EPA Compliance Status
Meets all federal Safe Drinking Water Act standards.
Notable Contaminants & Context
- •PFAS from the 3M plant in Decatur contaminated the Tennessee River — but Decatur sits downstream of Huntsville's intakes, so the plume affected West Morgan-East Lawrence customers, not Huntsville; local monitoring shows low levels
- •Disinfection byproducts from river water are monitored and kept within EPA limits
- •Karst groundwater sources are monitored for surface influence and treated accordingly

| Contaminant | Detected | Limit | Status |
|---|---|---|---|
| Chlorine (total) | 1.6 mg/L | 4.0 mg/L | ✓ |
| Fluoride | 0.72 mg/L | 4.0 mg/L | ✓ |
| Lead (90th percentile) | 2.4 µg/L | 15.0 µg/L | ✓ |
| Nitrate (as N) | 0.74 mg/L | 10.0 mg/L | ✓ |
| TTHM (Total Trihalomethanes) | 33.8 µg/L | 80.0 µg/L | ✓ |
| HAA5 (Haloacetic Acids) | 23.4 µg/L | 60.0 µg/L | ✓ |
✓ = below limit ⚠ = above health goal ✗ = exceeds guideline
How It Compares
River geography spared Huntsville the PFAS crisis that hit utilities just downstream near Decatur; its intakes pull water before it passes the industrial discharge points.
Tips
- •No filter is needed for safety; carbon filters are optional for taste
- •Huntsville Utilities publishes annual quality reports including PFAS sampling
- •Rapid growth means ongoing plant expansions; conservation requests can appear in peak summer
