2-methylisoborneol (MIB) and geosmin are problematic compounds in the water industry. Cyanobacteria in algae and actinomycetes in bacteria produce these compounds naturally in surface water sources, which, if not removed can be detected in drinking water.
Humans are able to detect the musty/earthy odour of these compounds at extremely low levels, 5ng/L for MIB and 30ng/L for geosmin respectively. Water testing methodologies therefore require equally low detection limits to identify these compounds and treat the water.
