To understand the relationship between soil contaminated factors and health of ChangHwa County area; this study examines the Taiwan EPA farmland soil heavy metal investigation and contaminated site control data in Chang-Hwa area from 1991 to 2002. Using Geographic Information Science (GIScience), we examine five different heavy mental soil concentrations: Ni, Cd, Cr, Cu, and Zn from sample area, analyze the rivers and channels distributions and metal factory location. All of the interpolation models are tested with Root Mean Square Error (RMS error) and the best-fit model is chosen by the lowest RMS error. Cox Transformation was used to adjust the data. The results show that the soil of the investigation area in ChangHwa County is obviously polluted. Base on the Geostatistics study and the distribution of the irrigation channels; the area neighboring the investigated farmland is suspected being polluted. For the farmlands exceeding soil control standard, Geostatistics method is used to coordinate with the information of the irrigation system to clarify the contaminated area so as to be the basis of land control and remediation work. As to the farmlands, not being investigated in this project but with high pollution potential according to the Geostatistics study, detail investigations are suggested.

Learning Objectives:

1.Learn the Geostatistic application. 2.Apply the procedure for assessing the soil heavy metal investigation.
• Develop contaminated site control plan.
