Urban areas (residential, commercial, transportation), each of the points during the same rainfall in the same area, this study was evaluated by a survey to find out the basic data and the characteristics of non-point pollution on local characteristics was performed. To evaluate and compare a non-point source pollution concentrations. The conclusion of this study was to know the influence of non-point pollutants in initial rainfall. There was a difference during the same point was compared. The pollution levels were differences in the point-specific characteristics, the same point compared by rainfall when rainfall is low, the contaminant concentrations were high. Finally, when compared to the number of rainy days. The shorter the number of rainy days, the non-point pollutants were high.
