Timeline: From Decision to Drinking Water
Expect 3–6 weeks from your first call to potable water. NJDEP permit approval and water testing are typically the longest steps.
| Step | Duration | Notes |
|---|---|---|
| Hire Licensed Driller & Apply | ~1 week | Owner + driller signatures required for permit |
| NJDEP Permit Approval | 1–2 weeks | E-permitting review (faster than paper) |
| Drilling & Casing | 1–3 days | Depends on depth and geology (bedrock slower) |
| Well Development & Test | ½–1 day | Pumping/surge to develop flow |
| Pump/Tank Installation | ½–1 day | Set pump, pressure tank, connect power |
| Disinfection/Flushing | ½–1 day | Shock chlorinate and flush system |
| Water Sampling by Lab | ~1 week | Lab turnaround for bacterial & chemical tests |
| Hookup & Occupancy | Immediate | After passing tests and final approvals |
Permits & Process
Permitting Process
- Pre-drill Evaluation: Contact a licensed well driller. The driller surveys the site and advises on well location. Local Board of Health must approve the proposed well location to meet setback requirements.
- NJDEP Permit: The owner and licensed driller both sign; the licensed driller submits the e-permit application through NJDEP's portal. Permit fee: $130 (standard wells) or$250 (high-capacity ≥70 gpm). Approval typically takes 1–2 weeks.
- Drilling: Driller performs work per NJ construction rules (N.J.A.C. 7:9D-2). After drilling, driller submits a Well Record (as-built log) within 90 days.
- Testing: Well is disinfected (shock-chlorinated) and flushed. A bacteriological sample (total coliform/E. coli) is collected and tested before use.
- Local Approval: Board of Health issues certification or Certificate of Occupancy after reviewing water test results. Many townships require this before occupancy.
Setback Requirements (N.J.A.C. 7:9D-2.7)
The sewage-component distances are for Category 1 wells; Category 2 also has the 5-ft building and 25-ft fuel-tank rules. The Department may reduce the 150-ft seepage-pit distance as a permit condition with casing sealed into a confining layer or additional casing; greater distances may be required for contamination or threatening geology (7:9D-2.7).
Minimum Distances:
- 25 ft from building sewers
- 50 ft from septic tanks, distribution boxes and dry wells
- 100 ft from drain fields
- 150 ft from seepage pits
- 150 ft from cesspools
- 25 ft from fuel storage tanks (Category 1 and 2)
- Category 1 and 2 wells: 5 ft horizontally from buildings other than pump houses; Category 1 wells: 20 ft from wood frame buildings
Who Does What:
- Driller: Permitting, drilling, casing, grouting, well record
- Pump Installer: Pump, pressure tank, piping
- Homeowner: Payment, lab testing, record keeping
- Health Dept: Site approval, final certification
Water Quality
Well water testing in New Jersey
NJDEP under the Private Well Testing Act (PWTA) handles private well water quality in New Jersey. Beyond the PWTA requirements, NJDEP recommends annual bacteria and nitrate testing for all private wells.
Required testing: New Jersey’s Private Well Testing Act REQUIRES well water testing at every real estate sale, and landlords must test rental properties on private wells every 5 years.
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.
Recommended Testing Schedule
- Annually: Total coliform bacteria, E. coli, nitrates
- Every 3-5 years: Full chemical analysis including metals
- In Piedmont counties: Annual arsenic testing (see warning below)
- After any event: Flooding, well repairs, nearby construction, taste/odor changes
- Property sale/rental: Full PWTA panel (legally required)
Common New Jersey Water Quality Issues
Arsenic
Naturally high in Piedmont region (Hunterdon, Somerset, Mercer, Warren counties). ~20% of wells exceed NJ's 5 µg/L standard. Long-term exposure is carcinogenic. Test annually if in affected areas.
Nitrates
>33% of shallow agricultural wells exceed 10 mg/L EPA limit. Common in Coastal Plain farming areas. Unsafe for infants and pregnant women. Often co-occurs with pesticides.
Iron/Manganese
Common in Highlands and northern counties. Causes rust-colored (iron) or black (manganese) staining. Aesthetic issue that can clog fixtures. Treatable with filters or water softeners.
Hardness & pH
Most NJ groundwater is hard (high calcium/magnesium). Pine Barrens wells have very soft, acidic water (pH 3.8–5.2) with brown color. Water softeners or neutralizers can address these issues.
Bacteria
Surface influences or faulty well seals can introduce coliform bacteria or harmful microbes. Test immediately after flooding, nearby septic work, or agricultural runoff events.
Treatment Options
- Bacteria: Shock chlorination, continuous chlorinator, or UV disinfection
- Sediment: Spin-down or cartridge filters (1–5 μm)
- Iron/Manganese: Aeration + filtration, or water softener (ion-exchange)
- Hardness: Salt-based ion-exchange water softener
- Nitrates: Point-of-use reverse osmosis (RO) or distillation
- Arsenic: Granular ferric-oxide filters, activated alumina, or RO
- Acidic water: Calcite neutralizer to raise pH
Maintenance & Troubleshooting
Annual Maintenance Checklist
- Test water for total coliform bacteria and nitrates (minimum)
- Test for arsenic if in Piedmont region
- Check pressure tank air charge (typical 30-50 psi)
- Inspect wellhead seal and cap for cracks or corrosion
- Replace pre-filters and sediment cartridges per schedule
- Keep wellhead area clear of debris and chemicals
Warning Signs of Well Problems
- Loss of pressure/flow: Weak water, pulsing, or pump cycling rapidly (tank bladder issue)
- Discolored water: Brown/red (iron), black (manganese), cloudy (sediment or contamination)
- Odors/tastes: Rotten egg smell (H₂S), metallic taste (mineral corrosion), chlorine taste
- Staining: Rust-colored (iron) or green-blue (low pH/copper corrosion) on fixtures
- No water/dry well: Pump runs dry or won't pump (well went dry or pump lost prime)
- Unusual noises: Grinding, vibration, or air hissing from taps (equipment failure)
Find a Licensed Driller
New Jersey law requires a licensed water well driller and pump installerfor all well work. DIY drilling is illegal.
