What to Test For in Rialto Wells
The geology in Rialto — San Bernardino alluvial fan deposits — directly determines what contaminants you're likely to find in your well water.
Common Contaminants in Rialto
Based on local geology and decades of testing Rialto wells, here's what we typically find:
- Water hardness: 12-20 grains — this causes scale buildup on fixtures, water heaters, and appliances
- Total Dissolved Solids (TDS): 450-900 ppm — affects taste and can indicate other contaminants
- Specific to San Bernardino alluvial fan deposits: hard water (12-20 grains), nitrates, moderate to high TDS
Why Rialto Water Has These Issues
Inland Empire city west of San Bernardino. Mostly on municipal water but some outlying properties use wells. Good alluvial fan yields. Industrial and residential mix. Near I-10/I-15 junction.
This geological context explains why Rialto wells commonly show: hard water (12-20 grains), nitrates, moderate to high TDS.
Neighborhood-Specific Concerns
- North Rialto: hard water (12-20 grains), nitrates, moderate to high TDS
- South Rialto: hard water (12-20 grains), nitrates, moderate to high TDS
- Bloomington area: hard water (12-20 grains), nitrates, moderate to high TDS
- Riverside Avenue corridor: hard water (12-20 grains), nitrates, moderate to high TDS

Recommended Tests for Rialto Wells
- Basic test: Bacteria, nitrates, pH, hardness, TDS
- Mineral panel: Iron, manganese, sulfate (critical for San Bernardino alluvial fan deposits)
- Extended panel: Arsenic, uranium, radon (if applicable to your neighborhood)
When to Test Your Rialto Well
- Buying or selling a home in North Rialto, South Rialto, Bloomington area, Riverside Avenue corridor, Lytle Creek area
- Annual testing (recommended for all Rialto wells)
- After pump repair or well service
- If you notice taste, odor, or staining issues
- After heavy rains or drought (affects San Bernardino alluvial fan deposits aquifers)
