GEOSMIN & MIB IN DRINKING WATER
Geosmin (1,2,7,7-tetramethyl-2-norborneol) and MIB (2-Methylisoborneol) are organic compounds 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 these compounds and can detect their presence at levels near 10 parts per trillion (ppt). These compounds are mainly produced by blue-green algae (cyanobacteria) and actinomycete bacteria and have musty, earthy odors. As such, they are 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.
METHOD SUMMARY
Performed according to Standard Methods 6040D utilizing Gas chromatography/mass spectrometry (GC/MS) with solid phase microextraction (SPME).
SAMPLING SUMMARY
Collect (2) 40mL amber glass vials with Mercuric Chloride. Holding time is 14 days.
REPORTING LIMIT
2ppt for both compounds.
