底泥品質管理相關法規納入「土壤及地下水污染整治法」(以下簡稱土污法)修正條文施行後，行政院環境保護署已陸續公告相關法規，並於103年1月開始推動目的事業主管機關對該管水體的檢測申報作業。本計畫主要工作目標為(1) 協助辦理底泥品質定期檢測申報及管理作業、(2) 研擬新興污染物或持久性有機污染物在底泥中之管理作業、(3) 研擬水體底泥污染潛勢分級基準及後續行政作為與管制策略，及(4) 研擬底泥評估環境影響風險評估作業與整治規劃作業手冊等。 本計畫執行成果包括協助環保署進行底泥品質定期檢測申報及管理工作推動，針對底泥申報業務辦理2場次說明會及3場次教育訓練進行宣導。因應政府資訊公開之規定，建立「底泥資訊公開民眾網」，民眾可於網路上查詢已完成備查之底泥品質資料。底泥中持久性有機污染物以PFASs為標的化合物，挑選國內三大科學園區之放流水承受水體進行調查分析，調查結果以南部科學園區放流水口測站總濃度最高，建議依本計畫調查結果並持續累積調查資料，建議後續考量以正面表列將部份PFASs納入定期檢測管制。底泥分級管理則依各水體基本特性、水質及底泥品質資料，綜合評析並建立各水體環境品質及受污染潛勢分級基準。底泥污染查證挑選雙溪等8處水體進行調查，並提出河川、湖泊/水庫、灌溉渠道等三種類型水體之底泥調查及查證技術手冊。依據我國底泥品質管理需求，並參考國外先進國家之底泥管理方式，完成研訂底泥評估境影響風險評估作業與整治規劃作業手冊初稿。

Sediment could provide habits and food for aquatic wildlife and plays a crucial role in the cycles of nutrients in the aquatic ecosystem. Nevertheless, pollutants released from industries would contaminate the aquatic sediments. Contaminated sediments might directly or indirectly affect fishery products which we consume daily. Therefore, suitable ways are needed in managing sediments. The Environmental Protection Administration (EPA) of the Executive Yuan had declared some regulations to manage qualities of sediments. In order to make clear of sediment quality in Taiwan, it is necessary to assist competent authorities to detect and report sediment qualities and further to carry out management strategy and treatment technology evaluation; therefore, the EPA of the Executive Yuan offered the opportunity (this project) to study those issues. In this project, the main works were (1) To assist EPA on the regular inspection and management of sediment quality, (2) to develop the policy of managing emerging pollutants or persistent organic pollutants in the sediment, (3) to develop a baseline for the classification of pollution potential of sediments in water bodies and subsequent administrative acts and control strategies, and (4) Development of environmental impact and risk assessment and remediation planning operations guidelines. To assist the EPA in carrying out regular sediment quality inspection and management, the project is implemented to conduct 2 briefing sessions and 3 education and training programmes for the sediment declaration works. In response to the provisions of the government Information disclosure, the establishment of the "Sediment Quality System", the public can look up the complete declared sediment quality data. Investigation of the persistent organic pollutants in the sediment are preliminarily focused on some specific PFASs compounds, and the survey and analysis of the water bodies of the three major scientific parks in Taiwan are selected. Results shows that the highest concentrations were found in the drainage stations in the Southern Science Park, and it is recommended that routine investigation should be carried out continuously. It is also recommended that subsequent consideration be given to the inclusion of partial PFASs in regular testing controls with a priority list. According to the basic characteristics of water bodies, water quality and sediment quality data, comprehensive assessment and establishment of quality and pollution potential grading benchmark of waterbodies were estabalished. Eight waterbodies were selected to investigate for verification of pollution of sediments, and put forward to three types of water body sediment investigation and verification technical guidelines. According to the requirement of sediment quality management in Taiwan and refer to the advanced countries, the first draft of the guideline for risk assessment and remediation plan for polluted sediments is established.
