中文摘要	本計畫主要協助環保署研議地下水及監測井管理相關工作，包括監測井維護、地下水水質資料彙整及趨勢分析、地下水管理及法規制度規劃、整合評析各單位監測資訊，以及研析沿海地區地下水及土壤鹽化情形，建立調查方法，並提出後續地下水鹽化監測預警網之建置建議。有關監測井維護作業，主要係為延續民國93~100年之監測井功能評估與維護工作，健全區域性監測井功能，以確保水質採樣之代表性。本計畫共計完成67口監測井之井況評估工作、52口監測井之高程測量與驗證作業；依據井況評估成果，研判並辦理30口監測井之再次完井、完井成效驗證及完井後水質採樣分析工作，建構區域性監測井水質特徵及積垢潛勢分析，並依據前述成果完成監測井資料驗證及更新；為維持監測井功能正常，完成5口監測井之異物排除、1口監測井基座改善、3口廢井及監測井補充設置作業。另亦辦理完成1場次「監測井設置技術講習」及2場次「監測井維護技術教育訓練示範觀摩」。於本（101）年計畫已完成全數431口區域性井之功能總體檢，歷年監測井維護紀錄已依縣市為單位彙整並製作光碟，供地方環保機關留存參考。監測井管理及地下水質變化趨勢評析部分，本計畫以Mann-Kendall統計方式完成全國10大地下水區區域性監測井之水質趨勢分析，共納入412口監測井進行評析，趨勢分析及法規值比對結果顯示，共有87口超過監測標準且具上升趨勢、282口水質變化趨勢穩定、另43口則從未超過監測標準。431口區域性監測井中，建議調降其中325口監測井之監測頻率為1年2次，其餘106口則因曾有水質測項超過監測基準且呈現上升趨勢或未累積足夠監測數據，建議保持1年4次之監測頻率。檢討現行地下水及監測井管理現況，完備地下水監測管理制度，研修地方環保機關「監測井管理」考核指標，研擬監測井井鎖統一管理原則，落實監測井管理作業。完成地下水檢出揮發性有機物之應變作業原則，俾供地方環保機關參考依循。協助辦理「地下水水質監測井設置作業原則」及「地下水水質監測井設置作業要點」之修正及發布。此外，亦協助辦理各單位監測資訊整合作業，包括建立監測資訊交換機制、監測資訊整合平台之功能效益及數據品質整體評估，並將環評開發案件所作土壤及地下水監測資訊納入整合作業，提升資訊系統之功能性及完整性。沿海地區鹽化現況評析及預警監測部分，完成國內沿海地區土壤及地下水鹽化資料蒐集彙整，包含鹽化情形及可能成因，利用歷年環保署及水利署地下水檢測資料進行鹽化潛勢評析，提出現場調查作業規劃。於彰化縣芳苑鄉及雲林縣口湖、水林鄉等2處調查區域，共計設置10口簡易井；基於監測資源共享，完成包括調查區域內之環保署既有井、水利署既有井及簡易井，共計46口次之地下水採樣及分析，以及8點次之地表灌排水採樣分析；完成每處調查區域10點次，共計52個土壤樣品分析；綜合評析土壤及地下水鹽化現況，提出地下水鹽化預警監測網之建置建議，俾利回饋監測井網檢討，以收地下水資源保育之效。

摘要	The purpose of this project is to implement the groundwater monitoring wells management of EPA. Main tasks include monitoring wells maintenance, groundwater quality investigation, policy and regulation establishment, and monitoring data integration. The groundwater and soil salinization of coastal area is also concerned in this project. The sketch of salinization monitoring network is proposed to preserve the groundwater resources. Based on the achievement of the maintenance of the Regional Groundwater Monitoring Wells (RGMWs) from 2004 to 2011, the state assessment and elevation validation of 67 and 52 RGMWs, respectively, is completed to preserve the well function and facilitate groundwater quality investigation. According to the results, 30 RGMWs were collected to conduct well redevelopment and groundwater quality analysis. The groundwater quality characteristics and corrdible potential are evaluated. To maintain the regular function of the RGMWs, the obstruction of 5 wells are resolved, the concrete foundation of one well is repaired, and borehole rebuilding of 3 wells are completed. The workshops of demonstrations on installation and maintenance of monitoring wells are held in 2012. The borehole installation information and groundwater quality and maintaince results of all 431 RGMWs are validated. The Mann-Kendall Test is adopted in this project to evaluate the variation of groundwater quality in 10 groundwater catchments. According to the results, the qroundwater quality of 87 wells exceeded the standard value with deterioration and that of 282 wells are stable. The monitoring frequency of 325 RGMWs is suggested to revise as semiyearly investigation, whereas that of the rest 106 wells is suggested to retain as seasonal investigation. The management frame of RGMWs is proposed in this project, including the modification of the norm of RGMWs management, the conception of the locks of RGMWs, establishment of emergency procedure of detected groundwater VOCs issues, pronouncement of “Principle and practice for groundwater quality monitoring wells installation”. In addition, the integration of monitoring data from different administrations, including data transformation, website evaluation and data quality control are accomplished. The distribution and possible machenisms of soil and groundwater salinization of Fangyuan of Changhua County and Kouhu of Yunlin County are investigated in this project by soil and groundwater sampling and analyses. Totally 10 temporal monitoring wells are installed and 46 groundwater, 8 surface water and 52 soil samples were analyzed to comprehend the influence of seawater intrusion and inundation on groundwater salinization. The results facilitate the development of salinization monitoring network in the future for groundwater resource conservation.
