為加速國內污染行為人不明場址管理工作，環境部(前環保署) 選定過去調查及模場計畫成果之掌握度足夠、整治有急迫性、污染分區複雜之永康地下水污染場址為示範案例，建立污染行為人不明之含氯地下水污染類型場址管理模式。考量場址污染面積與濃度於短時間較難低於國內管制標準以下，由環境部(前環保署)於106~110年辦理1期專案計畫移除主要污染源，並獲得階段性污染控制。因應國家實施永續性管理政策，本場址有地下水污染物特性且分區性污染複雜之特性，本期計畫運用健康風險評估與地下水環境模式數值推估所得結果，完成危害性評估並研提未來場址可行之長期管理方案，包括有降低風險危害、阻絕暴露途徑、檢討執行成效及滾動式修正未達預期之矯正措施，及未來管理執行方向。本計畫完成2年共4次改善後成效或保固資料分析，並提出永康區鹽東段817地號可解除列管地下水控制場址。本計畫完成分析共4次污染持續監測資料，並提出永康地下水受污染使用限制地區修正或調整範圍，及提出未來長期監測衰減管理執行原則。完成蒐整場址持續累積數據，依據所擬定之場址改善期間成效分析工作流程，運用統計分析工具找出場址改善成效之各主成分影響參數項目，以及完成國內公部門投入場址整治分級管理相關作法原則，提供未來機關擬定管理方案參考。

In order to speed up the management of sites with unknown polluters in China, the Ministry of Environment (formerly the Environmental Protection Agency) selected the Yongkang groundwater contamination site as a demonstration site with sufficient knowledge of past investigation and model site planning results, urgent need for remediation, and complex pollution zoning. Case study to establish a site management model for chlorine-containing groundwater pollution with unknown pollution perpetrators. Considering that the pollution area and concentration of the site will be difficult to fall below the domestic control standards in a short period of time, the Ministry of Environment (former Environmental Protection Agency) will carry out a phase 1 project plan to remove the main pollution sources from 106 to 110 years and achieve phased pollution control. In response to the country's implementation of sustainable management policies, this phase of the plan uses the results of health risk assessment and groundwater environment model numerical estimation to complete the hazard assessment and develop feasible long-term management plans for future sites, including risk reduction, isolation Exposure pathways, review of implementation effectiveness, rolling correction of corrective measures that do not meet expectations, and future management implementation directions. This project completed a total of 4 improvement results or maintenance data analysis in 2 years, and proposed that the site No. 817 in the Yankong Section of Yongkang District can be delisted as a groundwater control site. This project has completed the analysis of a total of 4 continuous pollution monitoring data, and proposed the scope of correction or adjustment for Yongkang groundwater contaminated use restricted areas, and proposed the implementation principles of long-term monitoring and attenuation management in the future. Complete the continuous accumulation of data on the site, and use statistical analysis tools to find out the parameters affecting the main components of the site improvement effectiveness based on the proposed site improvement period effectiveness analysis workflow, and complete the classification of domestic public sector investment in site remediation Management-related practice principles provide reference for future agencies to formulate management plans.
