Water Environmental Testing Laboratory – W.E.T. Lab – is a State licensed and ELAP certified water testing laboratory, located in the Sierra Nevada foothills of Northern California. Originally founded in 1994 as a small family business, we have since grown to perform tens of thousands of State mandated, compliant water tests for private companies, municipalities, water districts and bottled water companies. We also perform water tests for individual home, farm, and ranch owners. No client is too large or too small to receive our quality service.

As a subsidiary of Blodgett Research, Inc., W.E.T. Lab is able to provide all types of water testing including microbial, chemical and mineral water tests; but we specialize in water potability – the test required by State and local health departments to insure drinking water is safe from bacterial, pathogenic hazards. Our standard time for delivery of printed test results is just five business days. If needed, expedited results are available for an additional fee.


All potability testing is performed in our new, state of the art facility by trained lab technicians. Their findings are then reviewed and validated by our senior microbiologist and water chemist, a PhD candidate in public health with over 35 years experience in water testing and treatment in both the public and private sectors.

Our corporate goals of Good Science, Strict Attention to Detail, and an Uncompromising Dedication to the Public Health not only define us, they drive us daily. Our services are fast, thorough, reliable, and affordable.


Nothing is more important to us than our clients’ health. To foster that we invite you to browse our website, learn about waterborne microbial diseases and our water testing methods. Please feel free to contact us with questions about the potability and safety of your own well or water system by calling (530) 677-5776. When W.E.T. Lab tests your water there are no confusing test strips for you to analyze, no colored samples to try and compare, no chemicals you need to handle. Since your testing is performed inside a State Certified laboratory there is no chance of you misinterpreting results and making an error that might endanger the health of your family.  When you choose W.E.T. Lab, you will have the services of skilled and experienced water scientists, working as a dedicated team to provide facts you can rely on. Your satisfaction is always guaranteed.
