ABSTRACT
The compounds 2-Methylisoborneol (2-MIB) and Geosmin are the primary source of the foul odor found in drinking water. Algal contamination is the primary cause of the formation of these compounds. Since Geosmin and 2-MIB have such a low odor threshold, even the slightest amount of them can produce an unpleasant odor and taste in drinking water. In order to detect 2-MIB and Geosmin at these low levels, the sampling and analysis of the water has to be optimized. Standard Method 6040D describes a procedure for the detection of 2-MIB and Geosmin using Solid Phase Micro Extraction (SPME) coupled with a Gas Chromatograph (GC) and Mass Spectrometer (MS). Selective Ion Monitoring (SIM) is used for compound detection down to the part per trillion (ppt) level. This examination will optimize the sampling and detection of 2-MIB and Geosmin.
