We test Tannins!

Tannins, also known as humic or fulvic acid, are natural organic materials derived from plants or soil that may enter water systems when water passes through the soil or is in contact with decaying vegetation. Tannins are not harmful when consumed but alter the aesthetic properties of the water. Water containing elevated levels of tannins will be faint yellow to tea- like in colour, have a bitter taste, and a musty to earthy odour. Surface water sources and shallow wells are more susceptible to tannins.
