Timeline: From Decision to Drinking Water
Expect 6–8 weeks from your first call to potable water. County health department processing is often the longest step.
Permits & Process
1. Site Evaluation & Permit
Hire a licensed well contractor. The contractor submits a Well Construction Permit (GW-1 form) to your county health department. The health dept conducts a pre-drill inspection checking setbacks from septic systems and abandoned wells.
2. Drilling
Once the permit is issued (by law within 30 days), drilling proceeds. The well is drilled, cased, and grouted. The driller may self-certify compliance if inspector not present.
3. Pump Installation & Inspection
The contractor installs pump, pressure tank, and wiring. The local health department inspects the completed wellhead and system.
4. Certificate & Testing
If construction meets requirements, the health department issues a Certificate of Completion. No well may be used before this certificate. Within 30 days, water must be tested for bacteria and metals.

Water Quality
Well water testing in North Carolina
The NCDHHS Private Well Water Program handles private well water quality in North Carolina. North Carolina recommends annual bacteria testing and periodic chemical panels through the State Laboratory of Public Health or a certified lab; your county health department handles sampling.
Required testing: Since 2008, North Carolina law requires newly constructed wells to be tested within 30 days of construction, administered by county health departments.
Not sure what to test for? See our national guide to well water testing or order a certified lab test kit shipped to your door.
Required Testing Panel
All new private wells must be tested for: bacteria (total coliform/E. coli) and arsenic, barium, cadmium, chromium, copper, fluoride, lead, iron, magnesium, manganese, mercury, nitrate/nitrite, selenium, silver, sodium, zinc, and pH. Testing is typically done by the State Lab via your health department within 30 days of completion.
Common NC Water Quality Issues
Iron & Manganese
Very common in NC. Causes rusty water and stains. Treatment: oxidizing filters or water softeners.
Arsenic
Common in central Piedmont volcanic rocks. Treatment: reverse osmosis or iron-oxide filters.
Low pH (Acidic)
Frequent issue. Corrodes pipes and leaches metals. Treatment: calcite neutralizer filters.
Nitrates
Elevated in agricultural areas (eastern NC). Treatment: reverse osmosis or ion exchange.
Bacteria
Contamination possible after floods. Treatment: shock chlorination or UV purifier.
Radon
High in uranium-rich Piedmont rocks. Treatment: aeration or activated carbon.
Ongoing Testing Recommendations
- Annual: Total coliform bacteria
- Every 2–5 years: Metals and nitrates
- After any event: Flooding, well repairs, taste/odor changes
Maintenance & Troubleshooting
Annual Maintenance Checklist
- Inspect well cap and casing for cracks
- Check pressure tank (2 psi below cut-in)
- Test water for bacteria annually
- Replace pre-filters or cartridges
- Keep records of all tests and repairs
Warning Signs of Well Problems
- Sudden drop in water pressure or flow
- Discolored water or rust stains
- Cloudy water or sand in faucets
- Foul odors or tastes
- Pump cycles on/off abnormally
- Spike in coliform or nitrates in tests
