本計畫為延續歷年土壤及地下水污染調查及查證工作計畫，其工作內容包括進行臺南市轄區內土壤定期監測、地下水定期監測、監測井外觀巡察維護、監測井廢井、加油站網路申報資料審查與現場稽查作業、污染場址之監督查核與查證驗證作業、突發污染狀況查證、緊急應變、教育宣導及行政配合事項工作。 本計畫已完成14筆地號土壤定期監測，監測結果麻豆區安業段472地號重金屬鉛濃度(1890 mg/kg)及鋅濃度(6010 mg/kg)，分別超過食用作物農地之管制標準值3.78倍及10倍；安定區港口段231地號測出重金屬銅濃度(415 mg/kg)超過土壤污染管制標準1.04倍，另有3處低於土壤污染管制標準但超過監測標準，其餘9處均低於土壤污染監測標準。 地下水已執行定期採樣與檢測51口井，總共完成89口次之檢測分析，計畫達成率為100 %。監測結果中:敬惠工業2口監測井地下水中三氯乙烯測值今(104)年第一季至第四季皆超過管制標準，近期(104年10月)測值分別為R00670：6.22 mg/L，超標124倍;R00673：1.86 mg/L，超標37倍。另烏山頭水庫場置性監測井SRL（永揚）002，自99年9月監測至今(104年10月)，地下水中砷測值範圍為0.0404～0.170 mg/L，顯示該區域砷環境背景值偏高，其餘場置性監測井地下水質與歷年監測結果相似。監測井外觀巡查維護數量累計358口次，依據監測井巡查結果完成監測井修繕38口次；針對已無監測用途之7口監測井完成廢井作業。 加油站網路申報資料共審查859家，加油站之現場稽查工作已篩選30家名單完成進場查核。每2個月執行乙次列管場址監督巡查，迄今已巡查542場次，並將相關巡查紀錄上傳至土壤及地下水資訊管理系統；列管場址查證驗證工作分別為14處驗證場址及3處查證場址，其中2處驗證場址有超過污染管制標準，另3處查證場址有超過污染管制標準之情形，其餘場址均無污染之虞。 突發污染狀況查證共配合執行4件工作，執行結果發現位於本市和順工業區鄰近之嘉南大圳流域的上游及中游底泥重金屬鋅、鎳、銅、汞及砷等項目超過品質指標下限或上限值，其中以中游位置最為嚴重；保安工業區一口監測井中氯乙烯超過管制標準，其餘場址調查結果則均低於管制標準。 緊急應變工作土基會預算經費支應15處場址執行污染查證作業共80萬元，本項經費已支應100 %。協助環保局執行場址報告審查、土水法第8、9條及地下儲槽系統所提設置計畫、完工報告書文件審核及建檔共193件，並舉辦2場次法規宣導說明會、一般民眾宣導2場及一場大型宣導活動。

This project is an extension of Fy 103 “Soil and Groundwater Pollution Investigation and Verification Plan,” and the scope in this project includes the regular soil and groundwater quality monitoring within the venue of the City of Tainan, inspection and maintenance of the existing monitoring wells, well abandonment, examination and inspection of on-line website declare information from gasoline stations, check and verify on operations of polluted control sites, examine of pollution events, emergency and contingency plan, and provision of educational outreach meeting and administrative affairs. At the end of this year’s project the following work have been completed: execution of regular soil quality monitoring of 14 sites within the jurisdiction area and the concentrations of identified metals lead (1,890 mg/kg) and zinc (6,010 mg/kg) exceeding the Control Standards by 3.78 and 10 times, respectively at 472 nd lot site of Ma-dou District; concentration of copper (415 mg/kg) exceeding the Control Standard by 1.04 times at 231st lot site of An-ding District. Additionally, three of the sites the regulated substances are below the Control Standards but exceed the Monitoring Standards.At the remaining 9 sites all the regulated substances are all below the regulations. 51 wells were sampled and analyzed within the scope of work and 89 ground water samples completed. The results showed that two wells at Jing-huei Industry contained concentrations of TCE at levels exceeding the Control Standard through all 4 seasons of 2015, and results of the latest season indicated that TCE level was at 6.22 mg/L in R00670 and 1.86 mg/L in R00673, which were exceeding the regulated standard by 124 times and 37 times, respectively. Concentration of Arsenic(As) content from a specific monitoring well SRL (Yuon-yang) 002 at site Wu-san-tou Dam, was continuously detected at levels ranging from 0.0404 through 0.170 mg/L from September 2010 through October 2015. Above results show that the background of this area has high values of arsenic, and data of arsenic in the remaining site specific monitoring wells showed at similar levels detected previously.358 monitoring wells on site inspection were completed and 38 of them were repaired; and 7 wells were abandoned exactly based on regulated procedures. On-line website declaration information from 859 gasoline stations were examined one by one and 30 of gasoline stations from them were selected for further on-site inspection. Also, 542 bi-monthly visits and inspections for the control sites were completed and the visiting records were sent to the Soil and Groundwater Data Management System by internet. Totally 14 facilities sites for examination procedure and 3 others for verification procedure were conducted. Among the examination facilities, 2 sites were identified to contain chemicals exceeding the Control Standards. Result from All facilities for verification procedure, 3 of them show containing chemicals at levels exceeding the regulatory standards. There are 4 emergency pollution event examinations were executed in this project and the result indicated that heavy metals such as: zinc, nickel, copper and mercury were found to exceed the lower and the upper limits of target goals at the sections near upper- and mid-streams of Great Jia-nan Furrow along the City of Tainan and He-sung Industries Park; especially, the mid-stream portion of the furrow were more serious. One monitoring well at Bau-an Industries Park was found to contain vinyl chloride at level exceeding the Control Standard, the rest of sites were all below the Control Standard. 800,000 NT $ funding under the support of EPA Soil and Groundwater Pollution Remediation Foundation，were used for the emergency and contingency responses for 15 potentially contaminated facilities and the budget of this task achieved 100 % completion. In this project we also assist Tainan EPA to complete tasks on review of site operational reports, compliance of Articles 8 and 9 of “Soil and Groundwater Remediation Code”, placement of underground storage tank system proposals, document examination and filing, and there were 193 cases were completed. In addition, two environmental protection-related educational outreach meetings, two public advocacies and one large scale outreach activity were conducts and completed.
