Professional Well Drilling in Ontario
Southern California Well Service drills new wells throughout Ontario. We understand the local geology (San Bernardino alluvial fan deposits) and know what to expect at typical depths of 200-400ft.
Ontario Well Drilling Specifics
- Geology: San Bernardino alluvial fan deposits
- Typical depth: 200-400ft
- Expected yield: 10-30 GPM
- Water quality: hard water (12-20 grains), nitrates, industrial contamination concerns
- Elevation: 1,000ft
Why Ontario Geology Matters
Large Inland Empire city. Ontario International Airport. Major industrial and logistics hub. Mostly on municipal water but some industrial/agricultural wells remain. Good alluvial fan yields.
This geological context means Ontario wells require: 200-400ft depths to reach productive water-bearing zones in San Bernardino alluvial fan deposits.
New Well Drilling Process
- Site evaluation: Review property, existing wells nearby, geology maps
- Permits: Pull San Bernardino County well permits
- Drilling: Rotary or cable tool drilling through San Bernardino alluvial fan deposits to 200-400ft
- Well development: Pump and clean well to maximize yield (target: 10-30 GPM)
- Pump installation: Size and install submersible pump based on actual yield
- Water testing: Test for bacteria, minerals, and hard water (12-20 grains), nitrates, industrial contamination concerns
- System completion: Pressure tank, controls, final inspection
Expected Yields in Ontario
Wells in Ontario typically produce 10-30 GPM. This is enough for:
- Single-family homes (plenty of capacity)
- Larger households
- Irrigation and livestock watering
- Small agricultural operations
Drilling Costs for Ontario Wells
Well drilling costs depend on:
- Depth: Ontario wells typically need 200-400ft = $9000-22000
- Geology: San Bernardino alluvial fan deposits affects drilling time and bit wear
- Site access: Some Ontario properties difficult to access with drill rig
- Permits: San Bernardino County permit fees
- Pump system: Sized for actual well yield
Neighborhoods We Drill In
We've drilled wells throughout Ontario, including North Ontario, South Ontario, Airport area, Euclid Avenue corridor, Cucamonga area, and surrounding areas.
San Bernardino County Permits
All Ontario wells require permits from San Bernardino County Environmental Health. We handle:
- Permit applications and fees
- Site plan submittals
- Well construction reports
- Final inspection coordination
Water Quality in Ontario Wells
Based on San Bernardino alluvial fan deposits, expect these water characteristics:
- Hardness: 12-20 grains (softener likely needed)
- TDS: 450-900 ppm
- Common issues: hard water (12-20 grains), nitrates, industrial contamination concerns
We include basic water testing with every new well and can recommend treatment systems if needed.
