The structure of a turbidity concept is indistinct because turbidity measurement is sensorial. The authors tried to clarify the structure in this study. The analysis procedure of the experimental results is as follows : first, the scaling of turbidity is carried out, and second, its structure is clarified by means of multidimensional scaling and multiple regression analysis, It is concluded that there are three fundamental factors ; the particle concentration, the particle size and the color, and these factors are recognized as being of different importance depending on concentration.
