Why Test Your Well Water
23% Have Contamination
EPA estimates 23% of private wells contain at least one contaminant above health-based standards.

Unlike public water systems, private wells are not regulated. You're responsible for testing and safety.
Invisible Threats
Lead, arsenic, bacteria, and PFAS have no taste or odor. Only lab testing can detect them.
Recommended Testing Schedule
- •Annually: Test for bacteria and nitrates (minimum baseline)
- •Every 2-3 years: Comprehensive panel including arsenic, lead, uranium, VOCs
- •Immediately: Before home purchase, pregnancy, taste/odor changes, nearby land use changes
- •PFAS testing: If near military bases, airports, or industrial facilities ($300-$500)
