National Testing Labs


Tannins are naturally occurring organic material that can be created as water passes through soil and decaying vegetation. Tannins cause aesthetic issues like discoloration (yellow or tea color) which can cause staining on laundry, fixtures and fabrics. Tannis can also cause a slight taste to the water as well as a possible musty odor.  

This test will determine if Tannins are in your water. 

If you are performing testing to meet a regulatory requirement or if your results may be used for litigation purposes, please contact us for more information about testing packages designed for those purposes.
