中文摘要	本計畫調查執行期限自１０１年９月３日至１０２年９月２日止，主要針對桃園地區五個高污染潛勢之灌溉小組進行農地調查工作，並透過底泥與水質等傳輸途徑掌握目標族群內可能污染來源，以建立污染樣區之概念模式，計畫工作目標已全數達成。農地土壤調查共執行１６７１筆，其中６９０筆達管制標準，受污染面積約１０５公頃，超過管制項目以銅為主；以污染坵塊空間分佈，顯示引灌區域排水之灌溉小組具有高比例之污染；由底泥與水質調查結果，說明部分調查點位與特定可疑污染源具有相關性；另以地理統計判斷各項目標重金屬之危害範圍。由土壤、底泥與水質調查可歸納污染原因包括：１.桃園大圳供應灌溉水量或灌溉水路不足，致使部分農田引用受重金屬污染之區域排水(如：埔心溪、新街溪與三塊厝支線等)做為灌溉水源；２.鄰近工廠偷排廢水至灌溉渠道。３.工廠排放廢水雖符合放流水標準，但放流水標準高於灌溉水質標準，長期引灌導致重金屬累積於農地土壤。依重金屬空間相關性推估可疑污染源，提供清冊予環保局，作為加強稽查與求償依據；由歷史稽查紀錄中與污染源調查，有８家業者將未符合放流水標準之廢水排入灌溉系統中，預計將上述事業列為求償對象，並規劃預警系統，防止農地持續遭受污染。

摘要	The investigation of executing period of this project is from September 3, 2012 through September 2, 2013. The aim of this project was to investigate the agricultural land of five highly pollution potential irrigation groups in Taoyuan district. In addition, it was to govern the possible pollution sources within the target population via the transport pathways between sediments and water quality and to establish the conceptual model of pollution sample district. Up to the final term, planned objective has been fully met. Totally 1671 sets of agricultural land soils have been executed for the investigation. Among the investigation 690 sets have attained the control standard and the polluted area is around 105 ha. The exceeding item of heavy metal is mainly copper (Cu). The spatial distribution of polluted blocks shows that the irrigation group irrigated with district drainage has higher ratio of pollution. The investigation of sediment and irrigation water shows that partial investigated sites have correlated with some specific suspected pollution sources. Additionally, we have judged the hazardous range of each target heavy metal by using geographic statistics. From the consecutive monitoring results of soil, sediment, and water quality, the concluded causes of pollution include: 1) Insufficient water of Taoyuan large aqueduct leads to the agricultural blocks at downstream irrigated with district drainage such as Puhsin and Hsinje brooks and Sankuaitso branch, which has been polluted by heavy metals; 2) Vicinal factories have illegally discharged wastewaters to aqueducts; 3) Though the wastewaters discharged from factories meet the discharged water quality standard, it is more strict than the irrigation water quality standard. This results in the accumulation of heavy metals in agricultural soils via long-term irrigation. According to heavy metal spatial correlation to estimate suspicious pollution sources, we propose to provide Environmental Protection Bureau an inventory as a basis for strengthening inspection and compensation claims. Consecutively, based on the historical inspection records and investigation of pollution sources, the eight factories have discharged wastewaters which do not comply with discharged water quality standard into the irrigation system. We plan to list these factories as reparation-enquiry objects and further plan the warning system to prevent from persistent pollution of agricultural land in the future.
