Drinking Water Testing in California
Clean drinking water is essential for every home and business. Whether your water comes from a municipal water system or a private well, laboratory testing can provide valuable information about the quality of your drinking water and identify contaminants that cannot be detected by appearance, taste, or odor alone.
5 Microns provides mail-in drinking water testing throughout California, allowing homeowners, home buyers, landlords, businesses, and property managers to collect water samples using laboratory-approved bottles and submit them for professional laboratory analysis.
Whether you are purchasing a home, monitoring your drinking water, or investigating a specific water quality concern, we offer convenient laboratory testing for a wide range of common drinking water contaminants.
