「加油站土壤及地下水污染調查計畫(第六期)」(乙)
| 中文摘要 | 行政院環境保護署為預防土壤及地下水污染，確保土地及地下水資源永續利用，落實「土壤及地下水污染整治法」之規定，於99年辦理「加油站土壤及地下水污染調查計畫（第六期）（甲、乙）」，分別由美商傑明工程顧問（股）台灣分公司負責執行中北部區域之甲計畫工作，及中興工程顧問股份有限公司負責執行中南部區域之乙計畫（以下簡稱本計畫）工作，甲乙計畫共完成400站加油站土壤及地下水污染調查工作。 本計畫工作為辦理中南部區域共209站加油站土壤及地下水污染調查工作，以作為後續管制之依據。調查工作分為三個階段執行，第一階段調查為測漏管與土壤氣體檢測；第二階段調查為針對第一階段篩選出之具污染潛勢加油站進行土壤採樣分析及以簡易井進行地下水採樣分析；第三階段調查則為針對第二階段地下水超過管制標準之加油站，進一步設置標準監測井及進行地下水採樣分析。 本計畫第一階段調查共完成209站加油站3,628支測漏管基本功能測試及油氣之爆炸下限值(%LEL), 光離子偵測器(Photo Ionization Detector,PID) 及火焰離子偵測器(Flame Ionization Detector ,FID)檢測、25點土壤間氣體之PID及FID檢測，以及147點土壤氣體GC圖譜判釋作業。依調果顯示，測漏管油氣濃度測值經評估具高污染潛勢(A級)有3站，次高者(B級)有3站。另依據土壤氣體GC圖譜判釋結果，屬於1級者有2站，2級者有25站。 依環保署指示，本計畫第二階段之調查對象除篩選測漏管油氣濃度檢測結果為高污染潛勢及土壤氣體GC圖譜判釋結果屬1、2級者(共32站)外，亦增加環保署99年「加油站防止污染地下水體設施及監測設備查核暨網路申報諮詢計畫(以下簡稱查核計畫)」查核結果為高污染潛勢加油站11站進行調查，共計調查43站。 本計畫第二階段調查共完成43站加油站147點（699公尺）土壤採樣及檢測分析、108口簡易井地下水採樣及檢測分析。依檢測分析結果顯示，計有12站加油站之土壤污染物濃度超過土壤污染管制標準；有10站加油站之簡易井地下水污染物濃度超過地下水污染管制標準。於第三階段調查之10站加油站中，計有4站加油站之地下水污染物濃度超過地下水污染管制標準。 總結上述本計畫調查結果，其中土壤污染物濃度超出管制標準者有10站，地下水污染物濃度超出管制標準者有2站，土壤及地下水污染物濃度超出管制標準者有2站，均應依土壤及地下水污染整治法相關規定進行管制。此外，依據本計畫調查之加油站基本資料、加油站防止污染地下水體設施及定期監測申報資料等，與加油站污染之潛勢進行相關性分析，以提供環保機關做為後續行政管制措施之參考依據。 | ||

Investigating Soil and Groundwater Pollution at the Gas Stations in Taiwan (the Sixth Project) (B)
| 英文摘要 | In order to prevent soil and groundwater pollution, ensure the sustainable use of soil and groundwater, and fulfill the regulations of Soil and Groundwater Pollution Remediation Act, the Environmental Protection Administration (the EPA) initiated the Project of Investigating Soil and Groundwater Pollution at Gas Stations(the Sixth Phase)- Plans A and B in 2010, including 400 gas stations. MWH Taiwan was entrusted to carry out Plan A, covering Central and Northern Taiwan, while Sinotech Engineering Consultants, Ltd. (Sinotech) was assigned to carry out Plan B, covering Central and Southern Taiwan. Plan B performed by Sinotech was aimed to investigate soil and groundwater pollution at 209 gas stations in Central and Southern Taiwan. The findings from the investigation will be used as references for the follow-up pollution control activities. The investigation was implemented in the following three stages: 1. Stage 1: was to detect and measure the fuel vapor of soil gas monitoring well. 2. Stage 2: based on the results of Stage 1, was to conduct soil and groundwater sampling and analysis from simple wells at the gas stations with high pollution potential. 3. Stage 3: was to install standard monitoring wells and conduct groundwater sampling and analysis at the gas stations investigated in Stage 2 found to have groundwater pollutants beyond the control standard. For Stage 1, 209 gas stations were investigated, covering basic functional tests of 3,628 soil gas monitoring wells, measurement of fuel vapor concentration by using Lower Explosive Limit(LEL), Photo Ionization Detector(PID), and Flame Ionization Detector (FID), and measurement of soil vapor of 25 samples by using PID and FID, and gas chromatography(GC) analysis of 147 soil vapors. The results indicated that through the evaluation of the fuel gas concentration detected by soil gas monitoring wells, there were 3 gas stations with the highest pollution potential (Class A) and 3 gas stations with the second highest pollution potential (Class B). In addition, the result of soil vapor GC analysis indicated that 2 gas stations with the highest pollution potential (1st Class) and 25 gas stations with the second highest pollution potential (2nd Class) For Stage 2, 43 gas stations were investigated, consisting of the detection and analysis of 147 soil and 108 groundwater samples from simple wells. The findings showed that the soil pollutant concentration of 12 gas stations and groundwater pollutant concentration from the simple wells at 10 gas stations were over the control standard. For Stage 3, 4 out of the 10 gas stations investigated had the groundwater pollutant concentration over the control criteria. It was concluded that the soil pollutant concentration of 10 gas stations and groundwater pollutant concentration of 2 gas stations were above the respective control standards. Moreover, 2 gas stations had soil and groundwater pollutant concentration above the control standard. All of these polluted stations should be remedied in accordance with the Soil and Groundwater Pollution Remediation Act. In addition, the correlation analyses of the basic data of the gas stations investigated in the project, groundwater pollution control facilities, periodic declaration reports, and pollution potential at the gas stations were also conducted. The outcomes will serve as references for the environmental protection agencies in the follow-up administrative control measures. | ||
