中文摘要	本場址於民國90年經行政院環境保護署執行「地下水潛在污染源調查計畫」，發現地下水受含氯有機溶劑污染，隨後臺南市政府環境保護局針對本場址關切區域進行污染調查、設置緊急應變措施避免污染物持續擴大、釐清可能污染行為人、污染範圍等多年計畫。環保署為有效整合過去調查資料、發展適合場址之污染改善技術並研訂整體區域管制策略，特研擬本「臺南市永康鹽行段及鹽東段地下水污染評估與調查計畫」計畫。彙整分析歷年調查資料及本計畫成果，顯示計畫場址污染團中心區污染濃度維持在高濃度狀態，結合精確整治（Surgical Remediation, SR）觀念，配合本計畫現場水文地質、地下水質等補充調查作業以及雙環塞滲透灌注工法，經由現地模場試驗區之整治技術試驗、整治評估、地下水健康風險評估等，顯示技術上可克服低滲透性之地質，有效傳輸藥劑，透過現地生物刺激降解污染物，可達到污染攔截及污染削減之目標。地電阻探測顯示以高壓噴射攪拌灌注工法灌注之攔截系統，藥劑可均勻分布在攔截區及可長效停留在灌注區。根據補充調查、模場現地試驗及健康風險評估等結果，規劃後續污染管理計畫執行推動方案，提出行政管制與污染削減應變併行、分區分期污染削減應變執行推動計畫，提供決策參考依據。

摘要	Tainan EPB has conducted a series of investigation and contingency projects at this site since the chlorinated solvents contamination was found in the region of Yanhang and Yandong Sections, Yong-Kang District, Tainan, in 2001. In order to integrate the results of previous projects, develop remediation technology for this site, and obtain the contamination management strategy of whole region from the perspective of contamination conceptual of the site, EPA conducts this project “Groundwater Pollution Evaluation and Investigation of the Yanhang and Yandong Sections, Tainan”. The results of contaminant concentration tendency analysis showed the stable high concentrations in the mainstream area of contamination plume. Combining the concept of surgical remediation and the detail investigation for the two pilot test sites, the results of the pilot tests that performed in-situ bio-stimulation remediation using double packer injection method showed excellent performances. Those included delivering reagents into low permeability strata, reducing contamination and restricting contamination plume migration. The results of electric resistivity tomography showed the high pressure jet grouting mixing injection technology is able to make the reagents mix well with soil in the barrier region and stay in site for long duration. Based on the results of site investigation, pilot tests, and health risk assessment, a 2-8 year short-medium term of contamination management plan for this site were made. Administration measures and contaminant reduce contingency acts carrying out by stage and by area are included in the suggested plan.

摘要

Tainan EPB has conducted a series of investigation and contingency projects at this site since the chlorinated solvents contamination was found in the region of Yanhang and Yandong Sections, Yong-Kang District, Tainan, in 2001. In order to integrate the results of previous projects, develop remediation technology for this site, and obtain the contamination management strategy of whole region from the perspective of contamination conceptual of the site, EPA conducts this project “Groundwater Pollution Evaluation and Investigation of the Yanhang and Yandong Sections, Tainan”. The results of contaminant concentration tendency analysis showed the stable high concentrations in the mainstream area of contamination plume. Combining the concept of surgical remediation and the detail investigation for the two pilot test sites, the results of the pilot tests that performed in-situ bio-stimulation remediation using double packer injection method showed excellent performances. Those included delivering reagents into low permeability strata, reducing contamination and restricting contamination plume migration. The results of electric resistivity tomography showed the high pressure jet grouting mixing injection technology is able to make the reagents mix well with soil in the barrier region and stay in site for long duration.
