Well Water Testing in California

Private well owners are responsible for monitoring the quality of their own drinking water. Unlike public water systems, private wells are not routinely tested by a municipal utility, making laboratory testing an important part of maintaining water quality.

5 Microns provides convenient mail-in well water testing throughout California, allowing homeowners, property buyers, real estate professionals, and lenders to obtain professional laboratory analysis without scheduling an on-site appointment.

Whether you need routine monitoring, water testing for a real estate transaction, FHA or VA financing, or laboratory analysis for specific contaminants, our mail-in testing program makes professional laboratory testing available throughout California.

Laboratory testing may be appropriate when:
