環保署於民國99至106年針對全國重金屬高污染潛勢農地推動土壤污染調查，其後於107年起推動農地土壤污染預防工作。經查近年農地污染型態除透過灌溉圳路之低濃度長期累積，尚發現工農混雜區事業，排放高濃度廢水經道路側溝或不明渠道，介入農田水利灌排系統污染農地土壤。爰此，環保署委辦「農地土壤污染源管理計畫」，期建立長期且有效之避免農地遭受污染源影響的預警與預防程序，主要工作包含蒐集臺灣、美國、德國、日本及中國污染源管理策略，研擬因應臺灣現況之主要重點工作，含括強化土地使用分區、暢通跨部會協調管道、完整公開違章工廠資訊及周延相關裁罰、輔導措施等，同時完成3處污染調查區域篩選及環境介質調查，依據可能污染介入點及工廠製程運作項目分別鎖定疑似污染行為人，並推估農地土壤重金屬增量趨勢及超標年限。本計畫亦彙整零星污染農地資料，協助訂定相關處理作業原則，研修農地土壤重金屬污染查證程序參考手冊並研擬污染溯源作業程序流程，另蒐整埔心溪、新街溪、南崁溪及老街溪農業相關水質保護措施及分析執行成效；於計畫執行期間，亦定期維護「全國農地土壤管理系統」正常運作，協助農地管理應用需求及資料整合界接。

Taiwan Environmental Protection Administration (EPA) has conducted investigation of farmlands with high heavy metal contamination potential from 2010 to 2017. In addition, the policy of farmland pollution prevention and management was also implemented by EPA in 2018. According to the survey of farmland pollution, farmlands were contaminated with low-concentration heavy metal through irrigation water over long periods of time. Moreover, factories in industrial and agricultural mixed areas illegally discharge large amounts of waste water, which contain high-concentration heavy metal, into unknown ditches and road gutter at last contaminate the irrigation water and farmlands. In order to establish the long-term effective precaution and prevention procedures to avoid heavy metal pollution in farmlands, the “Management Project for Pollution Source in Farmland Soils” is progressed. This project firstly focusing on searching for the pollution source management strategies in Japan, America, China, Germany, and Taiwan. After the information collecting and searching process, this project has proposed the strategies to prevent farmlands from being polluted with heavy metal, which mainly about enhancement of land use management, improvement of cross-department coordination, announcements of the information about illegal factories, and enactment of laws with penalties and guidance for factories. Secondly, three polluted zones were selected and investigated in this project. Based on possible pollution intervention points, suspicious polluters were defined according to each factory process operation in the zones. And with the results of environment investigation, the team has also evaluated the increasing trend of heavy metal concentration in farmlands. Through collecting and summarizing the information about sporadic farmlands contamination cases, and analyzing the performance of agriculture-related water quality protection strategies for Puxin stream, New street stream, Nankan stream, and Old street stream, the team in this project has made relevant regulations and proposed revising for “Reference Manual for Verification Procedures of Farmlands with Heavy Metal Pollution” and the draft of “Pollution Source Assessment Procedure”. During the execution of this project, the team has also regularly maintained the “National Farmland Soil Management System” and assisted EPA to manage farmland pollution sites and integrate data.
