Water Quality Testing in California

Water quality testing helps homeowners, home buyers, property managers, businesses, and real estate professionals better understand the quality of their water through professional laboratory analysis.

Whether your water comes from a municipal water system or a private well, contaminants cannot always be identified by appearance, taste, or odor alone. Laboratory testing provides objective analytical results based on the submitted sample.

5 Microns provides mail-in water quality testing throughout California, making professional laboratory testing convenient without requiring an on-site appointment.

What Is Water Quality Testing?

Water quality testing involves collecting a representative water sample and submitting it to a professional laboratory for analysis.

Depending on the laboratory package selected, testing may include:

• Lead
• Copper
• Iron
• Manganese
• Total Coliform
• E. coli
• Nitrate
• Nitrite
• Hardness
• Legionella

Testing may also be customized to evaluate specific water quality concerns.

Many water quality concerns cannot be detected without laboratory analysis.

Customers commonly request testing when:

• Purchasing a home
• Selling a home
• Applying for FHA financing
• Applying for VA financing
• Using a private well
• Experiencing unusual taste or odor
• Seeing staining on sinks or fixtures
