Water Testing in Lake Arrowhead, CA

What to Test For in Lake Arrowhead Wells

The geology in Lake Arrowhead — mountain granite and decomposed granite — directly determines what contaminants you're likely to find in your well water.

Common Contaminants in Lake Arrowhead

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

• Water hardness: 6-12 grains — this causes scale buildup on fixtures, water heaters, and appliances
• Total Dissolved Solids (TDS): 200-400 ppm — affects taste and can indicate other contaminants
• Specific to mountain granite and decomposed granite: low yields common, iron, moderate hardness

Neighborhood-Specific Concerns

• Lake Arrowhead Village: low yields common, iron, moderate hardness
• Arrowhead Woods: low yields common, iron, moderate hardness
• Deer Lodge Park: low yields common, iron, moderate hardness
• Twin Peaks: low yields common, iron, moderate hardness
