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.
