Geosmin Testing Services

Geosmin (1,2,7,7-tetramethyl-2-norborneol) is an organic compound which can contribute to an unpleasant odor in drinking water.

Although not considered a threat to human health, the human nose is extremely sensitive to this compound and can detect its presence at levels near 5 parts per trillion (ppt). This compound is mainly produced by blue-green algae (cyanobacteria) and actinomycete bacteria and has a musty, earthy odor. As such, it is of exceptional concern to drinking water facilities which draw their water from a surface water source, especially as the levels of algae rise and fall over the course of the year.

Paragon is capable of testing for Geosmin in drinking water by:

CAS Number 19700-21-1
Molecular Formula C12H22O
Molar Mass 182.3 g mol-1
Boiling Point 270-271 °C
