Reporting & Documentation
Construction Report Requirements
The construction report must include:
- Well location (latitude/longitude required)
- Depth and lithology (formation descriptions)
- Water-bearing zones encountered
- Casing sizes, materials, and depths
- Grouting/sealing information
- Pump test data (if conducted)
- Well yield and static water level
Record Retention
Contractors must maintain records of all well installations and pump systems at their office. Recommended retention: minimum 5 years.
Construction Standards (17 CAR Part 11)
Casing Requirements
- Steel: Schedule 40 or heavier, new ASTM-rated
- PVC: ASTM F480, NSF-certified for water wells
- FRP: Must meet NSF-61/ASTM standards
- Depth: In consolidated rock, ≥10 ft below surface or 1 ft into solid rock
- Joints: Must be watertight throughout casing length
Annular Seal (Grouting)
- Metal casing: Encase in ≥2″ cement grout from surface down ≥10 ft
- Upper annulus (top 5–10 ft): Seal with cement or bentonite grout
- Industrial/irrigation wells: Reinforced concrete slab (≥4″ thick, overlap 2 ft)
- All joints must be watertight to prevent surface contamination
- Curbed wells: 6″ concrete for 10 ft below ground
Setback Requirements
Disinfection
All new, reconditioned, or repaired wells for human consumption must be disinfected before service:
- Chlorinate system to ≥50 ppm for ≥24 hours
- Disinfect well with chlorine tablets or liquid
- Flush all piping with chlorinated water
- Test water for coliform bacteria after disinfection
Flood-Prone Areas
Wells must avoid flood-prone sites. If unavoidable:
- Industrial/irrigation wells: Casing must terminate ≥2 ft above known flood elevation
- Use special floodproof casing construction
- Ensure adequate surface seal to prevent floodwater entry
Permits
Rig Permit (Required)
Arkansas law requires licensed contractors to obtain a rig permitfrom ANRC before drilling any well (Ark. Code §17-50).
- Fee: $145 per well
- Submit to: Arkansas Natural Resources Commission
- Timing: Before mobilizing to site
- Contractor responsibility (not homeowner)
High-Capacity Wells
Wells withdrawing >50,000 gallons per day (≈35 gpm) require water-use registration with ANRC:
- Submit Water-Use Registration form to ANRC
- Report monthly withdrawals (October–March)
- Contact ANRC Water Management Division
Special Well Types
Geothermal (Heat Pump) Wells
Allowed under 17 CAR §11-604. Must meet standard location rules (11-502) and construction standards. Closed-loop and direct-exchange systems permitted.
Monitoring/Piezometer Wells
Follow standard drilling rules. No special permit beyond rig permit and driller license. Common in environmental and regulatory work.
Drilling Conditions by Region
- Pleistocene sand and gravel aquifers
- Typical depths: 100–200 ft
- High yields: 1,000–2,000 gpm possible
- Easy drilling, but watch for iron content
- Artesian conditions in some areas
- Cockfield Formation: 300–400 ft
- Sparta/Memphis aquifers: 200–1,000 ft
- Artesian pressure common
- Watch for arsenic in some areas
- Major municipal water source
- Low-porosity shales and sandstones
- Limited water availability
- Often requires deep wells (>300 ft)
- Fractured zones offer best yields
- Driven wells in shallow alluvium
Seasonal Considerations
- Spring floods: Common in Delta areas. Set casing ≥2 ft above flood elevation
- Water table fluctuations: Dramatic in alluvial areas during wet season
- Frost depth: Minimal (few inches in north), rarely affects drilling
- Scheduling: Schedule irrigation/shallow wells in dry season when possible
