What to Test For in Upland Wells
The geology in Upland — San Gabriel foothill alluvial fan deposits — directly determines what contaminants you're likely to find in your well water.
Common Contaminants in Upland
Based on local geology and decades of testing Upland wells, here's what we typically find:
- Water hardness: 10-18 grains — this causes scale buildup on fixtures, water heaters, and appliances
- Total Dissolved Solids (TDS): 400-800 ppm — affects taste and can indicate other contaminants
- Specific to San Gabriel foothill alluvial fan deposits: hard water (10-18 grains), nitrates, moderate TDS
Why Upland Water Has These Issues
Inland Empire foothill city. Mostly on municipal water but foothill areas (San Antonio Heights) have private wells. Excellent alluvial fan yields. Near Rancho Cucamonga. Mount Baldy views.
This geological context explains why Upland wells commonly show: hard water (10-18 grains), nitrates, moderate TDS.
Neighborhood-Specific Concerns
- North Upland: hard water (10-18 grains), nitrates, moderate TDS
- South Upland: hard water (10-18 grains), nitrates, moderate TDS
- San Antonio Heights: hard water (10-18 grains), nitrates, moderate TDS
- Cable Airport area: hard water (10-18 grains), nitrates, moderate TDS
Our Upland Water Testing Process
- Sample collection: We come to your Upland property and collect samples from the well
- Laboratory analysis: Certified lab tests for bacteria, minerals, metals, and contaminants
- Results interpretation: We explain what the numbers mean for your specific property
- Treatment recommendations: Based on your water quality, we recommend filtration, softening, or other treatment
Recommended Tests for Upland Wells
- Basic test: Bacteria, nitrates, pH, hardness, TDS
- Mineral panel: Iron, manganese, sulfate (critical for San Gabriel foothill alluvial fan deposits)
- Extended panel: Arsenic, uranium, radon (if applicable to your neighborhood)
When to Test Your Upland Well
- Buying or selling a home in North Upland, South Upland, San Antonio Heights, Cable Airport area, Foothill Boulevard corridor
- Annual testing (recommended for all Upland wells)
- After pump repair or well service
- If you notice taste, odor, or staining issues
- After heavy rains or drought (affects San Gabriel foothill alluvial fan deposits aquifers)
