Is Tap Water Safe to Drink in Durham?
Yes, tap water in Durham is safe to drink. The city owns and protects its own reservoirs — Lake Michie and Little River Reservoir — and the treated water meets all EPA standards with soft, low-mineral character.
Water Source
The City of Durham Department of Water Management draws from Lake Michie on the Flat River and the Little River Reservoir, both city-controlled watersheds north of town, treated at the Brown and Williams water treatment plants.
EPA Compliance Status
Meets all federal Safe Drinking Water Act standards.
Notable Contaminants & Context
- •Disinfection byproducts from treating soft surface water are monitored and kept within EPA limits
- •Legacy lead plumbing exists in some pre-1960 homes; corrosion control and free testing keep measured levels low
- •PFAS levels in Durham's protected reservoirs test low, unlike some downstream Cape Fear basin utilities affected by industrial dischargers
Water Quality Data

| Contaminant | Detected | Limit | Status |
|---|---|---|---|
| Chlorine (total) | 1.5 mg/L | 4.0 mg/L | ✓ |
| Fluoride | 0.71 mg/L | 4.0 mg/L | ✓ |
| Lead (90th percentile) | 2.3 µg/L | 15.0 µg/L | ✓ |
| Nitrate (as N) | 0.67 mg/L | 10.0 mg/L | ✓ |
| TTHM (Total Trihalomethanes) | 31.4 µg/L | 80.0 µg/L | ✓ |
| HAA5 (Haloacetic Acids) | 21.8 µg/L | 60.0 µg/L | ✓ |
✓ = below limit ⚠ = above health goal ✗ = exceeds guideline
How It Compares
Durham benefits from owning its watersheds outright — its reservoirs avoid the industrial PFAS pressure seen in the Haw River and lower Cape Fear communities elsewhere in the Triangle region.
Tips
- •Soft water lathers easily and is gentle on appliances; no softener needed
- •Free lead testing is available through the city for older homes
- •Durham publishes its annual water quality report and reservoir levels online
