中文摘要	環保署於民國102年辦理「全國重金屬高污染潛勢農地之管制及調查計畫（第2期）」，透過灌溉單元篩選東西二、三圳灌溉系統中之嘉犁、鐵山支線小組辦理調查，發現40.0公頃污染農地受銅、鋅、鎳及鉻污染，其污染特徵與金屬表面處理業相關，引起各界高度關注。為進一步整體掌握東西二、三圳引灌農地之污染全貌，環保署乃辦理「彰化東西二、三圳地區農地污染調查計畫」（以下簡稱本計畫），以東西二、三圳流布範圍劃定9個灌溉小組為調查標的，評估空間面積為1,696.8公頃，並著重於農地土壤污染調查及重金屬污染空間關連性研判。農地調查係採取二階段調查方式，利用第一階段中尺度土壤調查資料作為推估基礎，以一般克利金模式推估第二階段小尺度調查區範圍，辦理逐坵塊土壤調查作業。為有效提升環境介質現勘、調查作業與主管機關對現地環境資訊掌握之效率，協助擴充「全國農地污染管理系統」圖層及資料，並實際運用環保署開發的調查輔助工具執行現場作業及提出回饋意見。依據本計畫二階段土壤調查成果，中尺度調查總計採集320組土壤樣品，其中89組疑遭重金屬污染物介入。第二階段調查總計採集1,705組土壤樣品，其中498組超過土壤污染管制標準，污染發現率為29.2%，公告管制面積100.2公頃，污染物主要為銅、鋅、鎳及鉻；依土壤調查結果辦理100組渠道底泥及20組水質採樣分析，底泥樣品檢測結果主要為重金屬銅、鋅、鎳及鉻之複合性污染，水質樣品檢測結果與農地土壤污染物介入樣態相符。經檢視調查區潛在污染源分布位置，完成篩選可疑污染源清單，並提供相關單位辦理後續污染事證查察。

摘要	The “2nd Control and Investigation Project for National Agricultural Land with High Potential for Heavy Metal Contamination,” commissioned by the Taiwan EPA in 2013, investigated the Jiali line and Tieshan line irrigation areas. These areas were selected from irrigation units in the East-West second and third irrigation system canals. This investigation detected 40.0 hectares of farmland contaminated with copper (Cu), zinc (Zn), nickel (Ni), and chromium (Cr). The specific contamination identified was related to the metal surface treatment industries, and there was widespread public concern about this event. In order to identify the distribution of contamination among farmland irrigated by the second and third East-west second and third canals, EPA carried out its “Investigation of Contaminated Farmlands in Changhua East-West Second and Third Canals Irrigation System”. The focus of this investigation was 9 irrigation areas in the East-West Second and Third canals irrigation system, and the area of the investigation region was 1,696.8 hectares. This project emphasized investigating the soil contamination of farmland and analyzing the spatial correlation between contaminated farmlands and heavy metal pollution sources. The investigation of contaminants in farmlands of 9 irrigation areas was implemented in two phases. In order to accelerate the efficiency of the environmental medium investigation and the supply of environmental information that the authority directed, geographic information maps and data from the “National farmland pollution management system” were continuously updated. Furthermore, this project also applied the supplementary investigation instrument which was developed by EPA for on-site investigations, and practical feedback was offered. According to results of the two-phase soil investigation, there were exceedances. The 1st phase collected 320 soil samples, and the heavy metal content of 89 soil samples was at levels probably exceeding soil pollution regulation standards. In the 2nd phase, 1705 soil samples were collected in total and 498 soil samples exhibited exceedance of the soil pollution regulatory standards (29.2% of samples were polluted, representing 100.2 hectares). The contaminants identified were Cu, Zn, Ni, and Cr. In addition, 100 sediment samples, and 20 water samples of irrigation ditches were collected. The results from sediment samples showed the composite contamination, including Cu, Zn, Ni, and Cr. The heavy metal content of water samples was consistent with the heavy metal content of contaminated farmland soil. Based on the investigation result of environmental media and the distribution of potential pollution sources, the register of suspected pollution sources was completed, and provided to relevant government units.
