Reporting & Documentation
Well Record Requirements (DEP-502)
The well record must include:
- Location (GPS coordinates in NAD83 state plane)
- Drilling dates and completion date
- Total depth and borehole diameter
- Lithology (formation descriptions by depth)
- Casing sizes, materials, and depths
- Well screen specifications (if used)
- Grouting/sealing information (materials, volumes, methods)
- Static water level and well yield
- Pump test data (if conducted)
- Driller\'s name and license number
Well Permit Requirements
Valid period: Standard permits valid 1 year; domestic use permits valid 2 years. Must be kept on-site during drilling and available for inspection.
Construction Standards (N.J.A.C. 7:9D)
General Requirements (N.J.A.C. 7:9D-2.2)
- Licensed driller must be on-site at all times during drilling
- All construction water must be potable quality
- All equipment must be clean to prevent contamination
- Hazardous drilling wastes must be handled per N.J.A.C. 7:26G
- Suspended/delayed boreholes must be abandoned as interim wells
Casing Requirements (N.J.A.C. 7:9D-2.3)
- Category 1 potable wells (rock): Minimum 6 inches inner diameter
- Casing height: Minimum 12 inches above grade
- Cap/vent: Down-facing screened vents at least 12" above grade
- Seal: Pitless adapter or watertight sanitary seal required
- Joints: Watertight (welded, threaded, or gasketed per WSC Pas-97)
- Materials: Corrosion-resistant steel or cement-lined as appropriate
Annular Sealing (Grouting)
Timing: All annuli must be grouted within 24 hours after casing is set
Approved materials (N.J.A.C. 7:9D-2.9):
- Neat Portland cement
- Cement-bentonite mixes
- Bentonite slurries (ASTM D5084 permeability ≤1×10⁻⁷ cm/s)
- Cementitious geothermal grouts (for closed-loop wells)
- Sodium-bentonite chips/pellets (gravity fill to 50 ft depth only)
Methods (N.J.A.C. 7:9D-2.10): Tremie-pipe or displacement methods required. Casing must remain suspended and vibrated to allow grout flow.
Setback Requirements (N.J.A.C. 7:9D-2.7)
Disinfection
All potable supply wells (Category 1) must be disinfected after installation, redevelopment, repair, or pump work per N.J.A.C. 7:10-11 (Safe Drinking Water rules). Common practice: shock chlorination with documented results.
Permits & Special Cases
High-Capacity / Public-Supply Wells
Wells producing ≈100,000 gpd (about 70 gpm) or intended for public supply/injection require detailed DEP review and approval. Applicants must include hydrogeologic data. DEP issues Certificates of Approval per N.J.S.A. 58:4A-18.
General Permit-by-Rule (No DEP Permit)
These activities are exempt from individual permits but still require well logs:
- Well repair/redevelopment
- Pitless adapter installations (including by pump installers)
- In-kind well screen replacements
- Shallow Category 4 or 6 wells (≤50 ft depth, ≤8.5" diameter)
- Elevator jackholes with proper casing
Site-Wide Permits
A single permit covering 10 or more wells of the same use on one property (e.g., monitoring or dewatering wells) is available for $1,300. After drilling, submit one combined Well Record form listing all wells.
Geothermal & Remediation Wells
Closed-loop geothermal (Category 5) and environmental/monitoring wells (Category 3/4) follow the same permitting process with specific N.J.A.C. 7:9D-2 standards. Deep injection wells for remediation require separate approvals from DEP's Ground Water Remediation program.
Drilling Conditions by Region
- Fractured crystalline (granite/gneiss) and Triassic basin rocks
- Hard-rock drilling (slow, may need cable tool)
- Yields vary; limestone fractures can produce >100 gpm
- Watch for arsenic in Piedmont lacustrine sediments
- Karst conditions possible in limestone valleys
- Hard metamorphics with moderate yields (10–50 gpm)
- Best yields in weathered zones
- Limestone valleys (Sussex, Warren) yield very well
- Potential for cavity collapse in karst areas
- Seasonal water table variations
- Thick sands and gravels (high-yield confined aquifers)
- Fast drilling (air rotary common)
- Typical depths: 500–2,000 ft
- Artesian conditions possible in deep confined units
- Brackish water common at depth
- Boreholes may require dewatering or drilling fluids
- Sand aquifer with shallow water table
- Very soft, acidic water (pH 3.8–5.2)
- Brown color common (high iron)
- Fast drilling in sand formations
- Watch for borehole collapse in loose sands
Seasonal Considerations
- Winter: Frozen ground (1–3 ft depth) can impede shallow drilling
- Spring: High water table from rains; potential site flooding and mud
- Summer: Drought can lower yields; easier site access
- Fall: Optimal drilling conditions in many regions
