本計畫的目標是針對交通部民航局所轄之18處民用航空站進行土壤及地下水污染之調查。調查過程主要區分為兩階段，第一階段調查主要進行土壤污染潛勢調查與查證及地下水污染潛勢調查工作，第二階段調查則篩選具地下水污染潛勢場址，設置標準井，進行地下水污染查證。 完成18處航空站現勘及初步評估後，篩選出11處航空站及所轄之30個單位，進行第一階段調查。由第一階段調查結果可知，台北航空站-航油中心、桃園機場公司-長榮航空、桃園機場公司-中華航空、桃園機場公司-航油處及桃園機場公司-焚化爐檢出土壤TPH超過管制標準，其中桃園機場公司-中華航空檢出土壤TPH濃度最高，為11,600mg/kg。另外，台北航空站-遠東航空電鍍廠附近之土壤鉻濃度超過土壤污染管制標準，濃度為724mg/kg。 第二階段調查於8個航空站所轄單位設置標準井，其中桃園機場公司-桃勤公司地下水中四氯乙烯濃度超過地下水污染管制標準102倍，濃度為5.12mg/L。此外，另5處航空站所轄單位地下水檢出Jet A1，由於Jet A1圖譜與柴油不同，不符合現行地下水污染管制標準，因此無法直接列管。本計畫探討Jet A1成分及油水相分布特性，並建議未來地下水管制標準油品項目應進行修正。 根據本計畫調查結果，建議台北航空站-航油中心、台北航空站-遠東航空、桃園機場公司-長榮航空、桃園機場公司-中華航空、桃園機場公司-航油處及桃園機場公司-焚化爐等污染場址，應依法進行污染改善，另外桃園機場公司-桃勤公司由污染初步評估辦法，已達整治場址等級，應依法進行後續行政管制程序。

The objective of this project is to conduct soil and groundwater pollution investigation of 18 airports that subordinate to the Civil Aeronautics Administration, Ministry of Transportation and Communications, Taiwan. Two-phase investigation was carried out in this project. The Phase I has proceeded soil pollution verified and groundwater pollution surveys. Following the groundwater pollution potential sites were selected and has verified in Phase II. After accomplishing site assessment of 18 airports and their subordinated units, 11 airports and 30 subordinate units were selected to investigate soil and groundwater pollution in Phase I. As results of Phase I show that several subordinate units of airports including Aviation Fuel Center in Taipei Songsan Airport, EVA Air in Taoyuan International Airport, China Airlines in Taoyuan International Airport, Incinerator in Taoyuan International Airport and Aviation Fuel Center in Taoyuan International Airport have TPH contamination in soil. The highest TPH concentration of soil is 11,600 mg/kg which was found at China Airlines in Taoyuan International Airport. The soil sampled near the electroplating factory of Far Eastern Air in Taipei Songsan Airport contained chromium (724mg/kg) which exceeded the Taiwan Soil Pollution Control Standards (TSPCS). Monitoring wells were installed in 8 subordinate units during Phase II. The results show that PCE concentration of groundwater in TIAS at Taoyuan International Airport exceeded the Taiwan Groundwater Pollution Control Standards (TGPCS). The highest PCE concentration was 5.12 mg/L which is 102 times higher than TGPCS. In addition, the groundwater was contaminated by Jet A1 in 5 subordinate units. However, the spectrum of Jet A1 was different from diesel that is pollution item in TGPCS. Thus, groundwater contamination of Jet Al has not directly controlled nowadays. According to the results of Jet A1 composition and oil-water phase distribution test, it was suggested that the definition and criterion of TPHd in TGPCS should be modified in the future. Based on Soil and Groundwater Pollution Remediation Act and results of this project, Aviation Fuel Center and Far Eastern Air at Taipei Songsan Airport, EVA Air, China Airlines, Aviation Fuel Center and Incinerator at Taoyuan International Airport should be remediated. For the preliminary assessment regulation, the TIAS at Taoyuan International Airport should meet remediation site level. Therefore, it has to conduct executive control process by Act.
