「加油站土壤及地下水污染調查計畫(第四期)」(甲)
| 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，及落實「土壤及地下水污染整治法」之規定，於96年辦理「加油站土壤及地下水污染調查計畫（第四期）（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，預計共完成400站(甲、乙兩計畫各200站)加油站土壤及地下水污染調查工作。 本計畫（甲計畫）工作為辦理中北部區域共200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200站加油站3,360支測漏管基本功能測試及油氣之LEL、PID及FID檢測，468點土壤間氣體之PID及FID檢測。依調查結果顯示，測漏管油氣濃度測值經評估具高污染潛勢者（A級）有9站，次高者（B級）有10站，合計為19站。依環保署指示，本計畫第二階段之調查對象除前述之19站加油站外，亦針對環保署「95-96年度加油站防止污染地下水體設施與監測設備查核暨網路申報諮詢計畫」中所查核之11站加油站進行調查，共計有30站。 本計畫第二階段調查共完成30站加油站105點土壤採樣及檢測分析，85點簡易井地下水採樣及檢測分析。依檢測分析結果顯示，計有5站加油站之土壤污染物濃度達土壤污染管制標準；有2站加油站之簡易井地下水污染物濃度達地下水污染管制標準。於第三階段調查之2站加油站中，計有2站加油站之地下水污染物濃度達地下水污染管制標準。 總結上述本計畫調查結果，共計有5站加油站之土壤污染物濃度超過管制標準，於該5站中有2站加油站之地下水污染物濃度亦超過管制標準，均應依土壤及地下水污染整治法相關規定進行管制。本計畫另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，與加油站之污染潛勢進行相關性分析，此外，亦彙整目前已經公告列管之加油站場址相關污染改善計畫報告，就場址列管狀態、場址基本資料(包括水文地質條件)、主要污染物質、污染改善工作執行單位及污染改善技術(工法)等資料進行彙整，以提供環保機關做為後續行政管制措施之參考依據。本計畫並另依據環保署要求，完成緊急應變調查工作。 | ||

Investigating Soil and Groundwater Pollution in Gas Stations
| 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 Water Pollution Remediation Act, the Environmental Protection Administration (the EPA) planned the Project of Investigation of Soil and Groundwater pollution for Gas Stations (4th Phase)- the Plan A and B in 2007. The scope of the Plan A covered central and north Taiwan and was carried out by MWH America Inc., Taiwan Branch. The scope of the Plan B (this Project) covered central and southern Taiwan and was carried out by Sinotech LTD. Plan A and B carried out the investigation of soil and groundwater pollution for 400 gas stations (200 gas stations for each Plan). This Project (Plan A) was to investigate soil and groundwater pollution for 200 gas stations in central and north Taiwan as reference in the follow up control activities. This project was implemented in three phases. The 1st phase was to measure the oil vapor density of soil vapor monitoring well. Based on the results of 1st phase, the 2nd phase selected gas stations with high pollution potential to conduct the detection and analysis of soil samples. In addition, groundwater samples from temporary groundwater sampling wells were also detected and analyzed. Based on the results of 2nd phase, the 3rd phase selected the gas stations with the pollutants’ density in the groundwater higher than the control standards to install standard monitoring wells and detect and analyze groundwater samples. The 1st phases was to test the basic functions of 3,360 soil gas monitoring wells, measure the oil vapor densities by using LEF, PID, and FID and the soil vapor of 468 samples by using PID and FID in 200 gas stations. The results indicated that the oil vapor density detected by soil gas monitoring wells in 9 gas stations with the highest pollution potential (A Class) and 10 gas stations with secondary pollution potential (B Class), totaling 19 gas stations. According to the instructions from the EPA, except the aforesaid 19 gas stations, the 2nd phase investigated the 11 gas stations listed in the Project of Inspection and Appraisal of Groundwater Pollution Control Facilities and Monitoring Equipment in Gas Stations, and Consultation on Internet Declaration System for 2006 and 2007. Totaling 30 gas stations were investigated at 1st phase. The 2nd phase conducted the detection and analysis of 105 soil samples and 85 groundwater samples from simple wells in 30 gas stations. As a result, it was concluded that the pollutants’ densities in the soil of the 11 gas stations had reached the control standards; the pollutants’ densities in the groundwater from the simple wells of the 2 gas stations had reached the control standards. The 3rd phase was to investigate the 2 gas stations. The pollutants’ densities in the groundwater of the 5 of them had reached the control standards. As a result, it was concluded that the detected pollutants’ concentration in soil of the 5 gas stations were higher than the control standards, and the pollutants’ concentration in groundwater of the 2 gas stations out of the 5 gas stations were higher than the control standards. All of them should be controlled in accordance with the Soil and Groundwater Pollution Remediation Act. Besides, a correlation of the basic data of the gas stations surveyed in the project, groundwater pollution control facilities, and their periodic declaration reports, vis-à-vis the pollution potential of the gas station was conducted and the results provided as references for the EPA in the follow up activities of administrative control measures. | ||
