In the current "Quality standards for drinking water" (CJ3020-93) qualitative and quantitative regulations on the smell of water were not established in our country. Flavor profile analysis can determine the type and magnitude of odor in the water samples qualitatively and quantitatively. Based on the flavor profile analysis method and SPME-GC/MS chemical analysis, a recommended value of the drinking water smell was given . The recommended value of 2-methylisoborneol(2-MIB) standards were obtained by investigating the 2-MIB standards in the diverse type of water sources, while the organoleptic and chemical analyses were considered with the situations of water treatment and the acceptance of consumers. The recommended values for both the first and second levels of water sources were both 10 ng/L and for the third level was 50ng/L. The recommended value of the 2-MIB smell standard provides a reference to divide by the water sources to some extent. Furthermore, this organoleptic analysis of the water quality can also recommond value and provide some profitable suggestions to the amount of 2-MIB in other city's water sources of our country.
