Our Mission

Ensuring that you have safe and palatable drinking water is of paramount importance to your health!


Mat-Su Test Lab provides water quality testing for your peace of mind.


We are not associated with water treatment companies, nor do we sell water treatment systems, so you never have to worry about a conflict of interest on our part! After we help you interpret your water quality test results, we'll be happy to refer you to knowledgable businesses in the Mat-Su Valley, should you need assistance with determining your water treatment needs.
