本研究計畫計調查彰化縣(市)、台南縣(市)、高雄縣及屏東縣計一零八公頃農地之重金屬濃度，以作為公告為控制場址之依據。調查結果指出，彰化縣地區農地超過管制標準之重金屬有Cd、Cr、Cu、Ni、Zn及As，農地受污染面積計70.35公頃；台南市地區農地超過管制標準之重金屬有Cd、Cu、Pb及Zn，農地受污染面積計1.86公頃；台南縣地區農地超過管制標準之重金屬有Cr、Cu、Ni及Zn，農地受污染面積計5.33公頃；高雄縣地區農地超過管制標準之重金屬有Cd、Cr、Cu、Ni、Pb及Zn，農地受污染面積計6.02公頃；屏東縣地區農地超過管制標準之重金屬有Cr，農地受污染面積計6.9公頃。此等資料均已建置完成以每一筆地號農地土壤重金屬含量清冊。並就本案調查範圍內每一塊農地，完成調查附近任何形式之地面水體(如灌溉渠道、各級排水路、河川等)、灌溉水質測站位置、相關縣市環保局列管500公尺範圍內水污染事業單位及各種可能污染源位置。此等調查資料，均已建置於每一公頃調查農地之套繪地籍數值檔，並以A3彩色圖印出，說明每一區塊農地可能之污染源及與圳道灌溉之關係。調查成果並列出農地面積小於0.01公頃，以及農地現況變化大，而未列入本案調查區域之農地土地清冊，並提供此等清冊及其背景資料蒐集之電子檔，同時以A3紙印製。最後建議於本案調查範圍內，Cr、Cu、Ni及Zn污染農地以混合稀釋法及反轉耕法，進行現地復育；Cd及Pb污染農地則以HCl溶液酸洗法進行現地復育；Hg污染農地或者以熱脫附法進行現地復育。

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
