金門縣因位處離島，其原垃圾處理方式主要以掩埋為主，而本縣早期之簡易掩埋場皆未鋪設不透水布，亦無垃圾滲出水處理設施，也無地下水監測井，期可能產生的地下水污染問題值得關注。因此透過本計劃調查已有掌握六座已封閉簡易掩埋場當地地下水水文狀況，並據以推估地下水可能污染程度與範圍。 本計畫主要工作為蒐集彙整有關六座已封閉簡易型掩埋場歷史基本資料、水文地質調查文獻及歷年地下水水質趨勢，並針對各掩埋場進行標準監測井設置及地下水質檢測作業，依據地下水質監測結果規劃六座已封閉簡易型掩埋場可行的地下水污染風險管理措施，及評估防止地下水污染擴散阻絕改善方案，以維護地下水品質及民眾用水安全。 各掩埋場地下水質檢測結果，主要以總溶解固體物質、氨氮、硝酸鹽氮、總有機碳等基本項目超過第二類地下水監測標準，且部分監測井有大腸桿菌群數目超過飲用水質標準的情形，其餘監測項目如八大重金屬及揮發性有機物檢測值皆低於第二類監測標準及管制標準。

Duo to the fact that Kinmen county is an isolated island,landfill is the original way of handling waste. The lack of waterproof, waste leachate treatment facilities, and groundwater monitoring wells ate common situations for earlier simple landfills in this county. These are potential problems for groundwater pollution that is worth concern. Hence, groundwater hydrogeology of the six closed landfills were investigated in this project in order to speculate the level and scope of groundwater pollution. The main tasks of this project were to collect basic information about these closed landfills including the past, hydrogeological references, and historical trend of groundwater hydrology. Based on the information, standard monitoring wells were established, and groundwater quality testing was made for each landfill. The feasible strategy of managing groundwater pollution risk was mapped out. The prevention and improvement of groundwater pollution were planned for these six closed simple landfills according to the results of water quality testing to secure groundwater quality and safe drinking water. From the results of groundwater quality testing of each landfills, total dissolved solids, ammonia nitrogen, nitrate and total organic carbon (TOC) were common categories that exceed second monitoring standards; number of E. coli exceeding drinking water standard occurred in some of the landfills as well. Besides, both testing values of eight heavy metals and volatile organic compounds (VOCs) were below second monitoring and control standards.
