本計畫共蒐集893口場置性監測井基本資料，主要分佈於工業區、大型獨立工廠、掩埋場、加油站、及污染查證等場址；針對其中設置時間超過2年且使用率較低之監測井，進行現勘、功能檢查與維護作業，總計執行356口；並就其中45口缺乏井細部設計資料或功能異常之監測井進行井底攝影工作，經井況評估確定己不能進行採樣之監測井為66口占總數之7.4％。另針對水質資料較缺乏或曾發現污染之113口監測井執行水質檢測，其中超出管制標準之污染物項目皆屬於氯化碳氫化合物，分別為1,2-二氯乙烷(2口均位於高雄縣林園工業區)、三氯乙烯與氯乙烯（各2口分別位於高雄市前鎮區與高雄縣林園工業區）。 北部地區高污染潛勢區採用「兩階段篩選」方法，首先建立高污染潛勢區候選名單，再由污染潛勢與水文地質綜合指標評定各區污染潛勢之高低，篩選出二十處區域；污染潛勢分析及模擬部分則引進模式參數並以可量化預警效益之美國MEMO模式來規劃井位；評估各潛勢區之既設監測井與污染潛勢高低，以及是否曾發生污染事件之歷史背景，使各區增設監測井控制於最少1站、最多4站之數量，同時配合各區域既設之場置性或區域性監測井，建構完整之預警監測系統。本計畫規劃結果共需增設60口監測井。 彙整監測井調查與維護工作成果，匯入「土壤及地下水污染場址資訊管理系統」中，並研訂「地下水監測井管理及水質監測作業手冊」（草案），內容包括監測井（網）類別說明、監測井管理制度介紹、監測井維護作業流程與方式、地下水水質監測、及「土壤及地下水污染場址資訊管理系統」介紹等，作為相關單位後續進行監測井管理維護與水質檢測工作之參考。

This plan collected basic data from a total of 893 site-specific monitoring wells; the locations of these wells are mostly in factories, dumping sites, gas stations, and potential contaminated sites. The 356 wells that were established over 2 years and seldom used were re-visited, checked and maintained their functions. Television Inspection system was conducted for 45 of the 356 wells, which were either lack of design detail information or malfunctioning. After the whole assessments, 66 out of 356 wells (7.4%) were confirmed as malfunction and unable conduct sampling process. Groundwater quality analyses were conducted for 113 wells, which were either lack of groundwater quality data or contaminated substances found previously. The results of the analyses showed that the concentrations of some chlorinated-hydrocarbon compounds were higher than the Groundwater Pollution Control Standards. 1,2-Dichloroethane was found in 2 wells located in Linyuan Industrial Area. Trichloroethylene and vinylchloride were found one located in Chien Chin District; another located in Linyun Industrial Area. To establish the “Potential Pollution Zone” in Northern Taiwan, “Two Stages Screening” method was used. First of all, constructed a Possible Potential Pollution Zone List; Secondly, combined the potential polluted index and hydrogeology index to evaluate the pollution degree of each zone and then select the top 20 areas. In analyzing and simulating the “Potential Pollution Zone“, MEMO model was used for planning the locations of new monitoring wells. After evaluating the historical pollution events of the areas, 1 to 4 monitoring wells were suggested in each area cooperating the existing site-specific monitoring wells and regional monitoring wells. As a result, 60 monitoring wells were planned to complete the construction the “Pre-warning Monitoring Well System”.
