中文摘要	本計畫主要目標係為延續民國93~96年之地下水監測井評估維護之工作，持續維護區域性地下水監測井，以維持監測井最佳狀態；另一方面同時驗證監測井基本資料以健全區域性地下水監測井網工作。本計畫依據民國96年8月至97年1月北中南三區監測井巡查維護紀錄，依「井深異常」、「回水緩慢」、「明顯混濁物」、「抽出水色異常」、「滯留水臭味」等5項原則篩選出40口監測井進行井況評估。茲將各項工作成果說明如下：一、定期維護區域性地下水監測井，維持監測井況正常 1.完成40口監測井之井下攝影與微水試驗等井況評估工作。因40口監測井中雲林縣育英國小因井下攝影發現監測井井內無水，另擇新竹縣二重國小替代。 2.完成32口再次完井工作，並施作微水試驗及井下攝影。包括井況評估結果建議先行完井者共計22口，另有2口監測井(苗栗縣照南國小及屏東縣餉潭國小)原有異物阻塞，已清除完畢並依土基會指示納入完井名單及配合環保署辦理之嘉義縣溪口國小與台東縣社區和平中心，以及前案計畫尚未完成之6口監測井。 3.完成3口監測井透水性分析，因地質紀錄與透水性分析不吻合之台北市玉成國小、台北市士林國小及台北縣德音國小。 4.完成30口監測井地下水採樣及水質檢測分析。另以Stiff及Piper圖解法分析水質趨勢。二、建立區域性地下水監測井基本資料庫，完成基本資料驗證更新，分析環境變化 1.完成90口監測井高程驗證，原監測井資料卡之高程，與本計畫引用一等水準點所進行測量之高程差距於-6.583公尺至35.994公尺間，而誤差超過10公尺共計有8口。 2.完成41口井篩驗證工作，本計畫以井下攝影進行井篩驗證工作，共計有台北市玉成國小等20口監測井井篩長度與資料卡資料差異資料較大外，其餘監測井井篩長度與資料卡上大致符合。 3.完成41口監測井之環境資料變化。本計畫依據歷年水位及基本資料卡紀錄之井篩位置分析前述41口監測井之環境資料變化，共計有22口歷年水位皆位於井篩區間內，共計有18口歷年水位超過井篩上緣或低於下緣段，共計有1口雲林縣育英國小因井篩區間過短故於枯水期井內呈現無水情形。 4.建置區域性地下水監測井基本資料庫，本計畫所設計建構之資料庫具有複合查詢、系統維護及統計分析等功能，並提供e化操作簡易介面作業，增加系統操作方便性及友善度。三、強化地下水監測井體設施，更新地表設備環境 1.完成更新90口告示牌。 2.完成苗栗縣照南國小等5口監測井異物排除作業。 3.完成台南縣官南國小等2口平台式監測井改為隱藏式。 4.完成新竹市虎林國小等6口防水井頂蓋施工 5.完成新竹市朝山國小及台東縣福原國小2口新設監測井及台東縣福原國小等5口廢井作業。

On the other hand, the basic well information was corrected in order to establish the integrity of the network of the RGMWs. According to the maintenance records of the wells inspected from 8/2007 to 1/2008, the 40 wells were screened to proceed the evaluation of well condition in this project through the five criteria of the “unusual well depth”, “groundwater recovery slowly”, “obvious turbidity in well”, “unusual color of groundwater”, and “the odor of retention groundwater”.
