本計畫主要調查台中縣、台中市、彰化縣、南投縣、等四個縣市共130座加油站之基本資料及土壤及地下水污染潛勢。 本計畫共完成130座加油站之基本資料調查工作，內容包括「加油站設置資料」、「地下油槽基本資料」、「管線基本資料」、「卸油資料」、「翻修資料」、「監測設備資料」、「加油槍油氣回收系統資料」、「SVE(Soil Vapor Extraction，土壤氣體抽除)設備資料」、「洗車用水資料」及「環境資料」等十大類別，調查結果將可提供環保單位作為後續資料庫建置與管理之參考。 本計畫共完成130座加油站、1607支測漏管油氣之LEL(Lower Explosion Level，低爆炸下限)、PID(Photoionization Detector，光離子檢測儀)及功能檢測(包括管蓋開啟、積水、透氣性等)，其中功能檢測不合格之測漏管數共28支，佔總檢測數之1.7％。依據測漏管油氣及功能檢測結果研判可能之污染潛勢，並予分級後共篩選42座需進一步調查之加油站進行測漏管油氣及土壤氣體採樣分析工作。 於進行測漏管油氣及土壤氣體採樣分析工作之42站中，本計畫共檢測131個測漏管油氣樣品及131個土壤氣體樣品。並依據各樣品苯、甲苯、乙苯、二甲苯及總石油碳氫化合物之分析結果，篩選出21座加油站進行土壤及地下水檢測工作。 於所調查之21座加油站土壤及地下水樣品中，計有台中縣國仕加油站等12站之檢測結果疑似有污染之虞。並於後續進一步辦理12座加油站之污染查證工作。依據查證結果顯示，計有8站之土壤或地下水污染物濃度超過管制標準，建議後續應依「土壤及地下水污染整治法」之規定進行相關管制措施。

In this plan, the background and pollution potential of underground environment in total 130 gas stations in middle-northern Taiwan had been investigated. Including “Gas station set-up data”, “UST(underground storage tank) basic data”, “piping basic data”, “unloading data”, “reparation data”, “monitoring equipment data”, “oil vapor recycling system data”, “car wash data”, “SVE(soil vapor extraction) equipment data”, “environment data” and so on, totally 10 kinds of data were collected to provide Taiwan EPA(Environmental Protection Administration) to do the follow-up works. In Phase I Investigation, we inspected 130 gas stations and 1,607 soil vapor monitoring wells by using LEL(Lower Explosion Level) detector, PID(Photoionization Detector) and checked the capabilities of those wells (including the cap could be opened or not, water accumulation and ventilation test, etc.). There were 28 soil vapor-monitoring wells failed. According to investigation results, 42 gas stations were screened to enter the next step (Phase II). In Phase II Investigation, we inspected 42 gas stations, sampled and analyzed 131 soil vapor samples from monitoring wells and 131 samples from direct push process. Base on the analyzing values of benzene, toluene, ethylbenzene, xylene and total petroleum hydrocarbons (TPH), 21 gas stations were sieved out to do soil and groundwater sampling investigation. (Phase III) According to the analyzing results of soil and groundwater samples, 12 gas stations have higher pollution potential among 21 gas stations. In order to confirm the pollution situation, Taiwan EPA assigned 12 gas stations to conduct the identification task. According to the identification results，8 gas stations were exceeding the “Soil Pollution Control Standards ” or the “Groundwater Pollution Control Standards”. Taiwan EPA have to do the follow-up control according to the “Soil and Groundwater pollution Remediation Rules”。
