The project was to investigate the heavy metal concentrations of 108 ha of agricultural fields distributing in County and City, Tainan County and City, Kaohsing County and Pingtung Conty, in order to use as the data for the announcement of “Control site”. The results showed that the heavy metals in the agricultural field in Changhua County, which concentrations exceed their control standards are Cd, Cr, Cu, Ni, Zn, and As. The polluted area of agriculture fields is 70.35 ha. The heavy metals in the agriculture fields in Tainan City, which concentrations exceed their control standard are Cr, Cu, Ni, and Zn. The polluted area of agriculture fields is 5.33 ha. The heavy metals in the agriculture fields in Kaohsiung County, which concentrations exceed their control standard are Cd, Cr, Cu, Ni, Pb and Zn. The polluted area of agriculture fields is 6.02 ha. The heavy metals in the agriculture fields in PingTung County, which concentrations exceed their control standard are Cr. The polluted area of agriculture fields is 6.90 ha. All the data of heavy metal contents for each land number of the agriculture field have been established the compilation. In addition, for each agriculture land, the investigation includes the vicinity of surface water bodies such as irrigation aqueducts, drainage aqueducts, the rivers, the position of irrigation water monitoring stations, and the water pollution industrials and the position of possible pollution surface within the range in 500m governed by the related Environmental Bureau of Counties and Cities. Moreover, these investigation data have been established in the digital files of overlapping maps for land registration and printed out by A3 size of color chart in order to depict the relationships between the possible pollution source and irrigation aqueduct for each block of agriculture fields, which not investigated in this project; the list of these date and the collected electronic file were provided to EPA. Meanwhile, the lists we
