Well Inspections in Ontario
Wells in Ontario face unique challenges due to San Bernardino alluvial fan deposits and local conditions. A thorough inspection identifies problems before they become emergencies.
What We Inspect in Ontario Wells
Well Casing & Construction
- Casing integrity: Check for cracks, corrosion, or damage (critical in San Bernardino alluvial fan deposits)
- Well seal: Ensure sanitary seal is intact (prevents surface contamination)
- Depth verification: Confirm well depth matches records (Ontario wells typically 200-400ft)
- Screen condition: Check for sand infiltration (common in San Bernardino alluvial fan deposits)
Pump System
- Pump performance: Flow rate test (should be 10-30 GPM)
- Motor condition: Amp draw, voltage, running temperature
- Pump depth: Verify setting is appropriate for Ontario water table
- Drop pipe: Check for leaks, corrosion, or age-related failure
Pressure & Storage
- Pressure tank: Check pre-charge, waterlogging, bladder condition
- Pressure switch: Test cut-in/cut-out settings
- Storage tanks: Inspect condition if applicable (common in Julian, Anza for low-yield wells)
Water Quality
- Visual inspection: Check for sediment, rust, odor
- Testing: Bacteria, hardness, TDS, specific contaminants (hard water (12-20 grains), nitrates, industrial contamination concerns)
- Flow rate: Measure actual GPM vs. expected (10-30 GPM)
Ontario-Specific Inspection Focus
Because Ontario wells are in San Bernardino alluvial fan deposits, we pay special attention to:
- Hard water, nitrates from historical agriculture, industrial contamination concerns, most areas on municipal water (limited residential well service), aging agricultural/industrial wells
- Geological factors: San Bernardino alluvial fan deposits can cause specific wear patterns
- Water quality: hard water (12-20 grains), nitrates, industrial contamination concerns
When to Get a Ontario Well Inspection
- Real estate transactions: Required for buying/selling homes in North Ontario, South Ontario, Airport area, Euclid Avenue corridor, Cucamonga area
- Annual maintenance: Recommended for all Ontario wells
- After problems: Following pump failure, contamination, or major repairs
- Pre-winter: Especially for high-elevation Ontario areas (elevation: 1,000ft)
- Drought assessment: Check well capacity during low water table periods
Our Inspection Report Includes
- Complete well specifications (depth, casing diameter, pump setting)
- Flow rate and pressure measurements
- Water quality test results
- Pump system performance data
- Photos of key components
- Recommendations for repairs or upgrades
- Estimated remaining lifespan of major components
Why Ontario Wells Need Regular Inspections
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.
These local factors mean Ontario wells are prone to: Hard water, nitrates from historical agriculture, industrial contamination concerns, most areas on municipal water (limited residential well service), aging agricultural/industrial wells. Regular inspections catch these issues early.
