無污染行為人場址先行改善計畫 - 永康地下水污染場址（第1期）
| 中文摘要 | 本計畫為無污染行為人場址先行改善計畫，係為行政院環境保護署為加速推動污染場址執行改善之示範性計畫，本計畫在污染改善上採精確整治的作法，結合智慧型表徵調查、多深度精確灌注、跨孔式地電阻探測藥劑傳輸等三者，動態回饋調整灌注設計，提升整治成效。本期污染改善規劃採A區高污染區污染攔截、B區污染源區改善、C區污染源區及下游污染團改善工作。經自行驗證及監督驗證，A區污染攔截區5口位於攔截牆下游驗證井之含氯污染物莫耳濃度總和變化，經統計分析已無上升趨勢，達到計畫目標；B區10口驗證井之各污染物均已低於管制標準，符合計畫目標；C區13口驗證井中除1口位於酸性環境之驗證井外，其餘12口驗證井之污染削減皆已達計畫目標。A區高污染區經生物添加模場試驗已促動高污染團降解，結合污染改善成果，場址氯乙烯污染範圍及濃度已大幅縮小或下降，健康風險減輕。改善計畫專設監督小組、監督驗證單位之審查、監督、驗證、驗收執行模式，及與開發工程單位之協調經歷，足可為其他場址示範參考。從土壤及地下水管理資訊系統彙編之國內地下水有機污染場址整治技術手冊，提供更多國內場址整治技術經驗，有利國內業界技術提升。 | ||

Anticipatory Improvement Project of Sites with No Polluter - Phase Ⅰ (A Groundwater Contamination Site at Yongkang District, Tainan City)
| 英文摘要 | This project is a non-polluter site remediation plan that is a demonstration plan for the Environmental Protection Agency of the Executive Yuan to accelerate the implementation of the remediation of contaminated sites. This plan adopts surgical remediation methods for pollution remediation, combined with the three parts of smart characterization investigation, multi-depth precise injection, and cross-hole earth resistance tomography detection of reagent transmission to feedback adjustment injection design dynamically, therefore improve the remediation effect. This phase of the pollution remediation plan includes pollution interception in the high-pollution area of Area A, the remediation of the pollution source area of the B area, and the remediation of the pollution source area of the C area and the downstream pollution plume. After self-verification and supervision verification, the total molar concentration of chlorine-containing pollutants in 5 verification wells located downstream of the interception wall in the pollution interception area of Area A has not increasing trend after statistical analysis and reached the planned target; 10 verification wells in area B all of the pollutants have fallen below the control standards and met the planned goals. Among the 13 verification wells in Zone C, except for one that is located in an acidic environment, the pollution reduction of the remaining 12 verification wells has reached the planned goal. The highly polluted area in Area A has promoted the degradation of highly polluted clusters through the bio-augmentation pilot test. Combined with the results of pollution remediation, the pollution plume range and concentration of vinyl chloride on the site have been greatly reduced or decrease, and the health risk has been reduced. The mode of the procedure of review, supervision, verification, and acceptance implementation under the special expert committee, supervision team, and the coordination experience with the development engineering unit, which can be well demonstrations for reference for other site. The domestic groundwater organic pollution site remediation technical manual compiled from the soil and groundwater management information system provides more domestic site remediation technical experience, which is beneficial to the technical improvement of the domestic industry. | ||
