Water Testing in Highland, CA

Know what's in your San Bernardino alluvial deposits well water

What to Test For in Highland Wells

The geology in Highland — San Bernardino alluvial deposits — directly determines what contaminants you're likely to find in your well water.

Based on local geology and decades of testing Highland wells, here's what we typically find:

Water hardness: 12-18 grains — this causes scale buildup on fixtures, water heaters, and appliances
Total Dissolved Solids (TDS): 450-800 ppm — affects taste and can indicate other contaminants
Specific to San Bernardino alluvial deposits: hard water (12-18 grains), nitrates in some areas

City near San Bernardino. Mix of residential and rural areas. Many properties on wells in outlying areas. Good alluvial well yields. Near foothills.

This geological context explains why Highland wells commonly show: hard water (12-18 grains), nitrates in some areas.
