計畫中文摘要	含氯溶劑地下水污染為全球非常重要的環境議題。含氯溶劑在低濃度下也被認為是致癌物和有毒物質。此類污染物很難整治，主要因為它們通常以重質非水相液體(DNAPL)的形式存在而外是到地下水。監測式自然衰減(MNA)指包括各種物理、化學或生物機制的自然衰減過程，在適當的條件下，無需人為的方式，可減少污染物的質量、毒性、遷移性、體積或濃度。在含氯溶劑污染場址，MNA為有效方法，因為自然衰減過程會破壞和降解污染物。使用 MNA 的決策須有場址資料和分析支持。為了評估MNA含水層整治措施的有效性，需要有長期的監測計畫。MNA的有效性在於要保護環境安全和公眾健康。數學模型廣泛應用於這些含氯溶劑污染場地。轉化產物的形成和降解對於含氯溶劑污染物傳輸非常重要。多物種傳輸解析解式以數學求解了一組由一系列一階降解反應耦合聯立移流-延散方程式，可同時合理地預測原始汙染物及其生成產物的傳輸。在多物種傳輸解析解模式中，美國環保署所提供的BIOCHLOR和REMChlor是最常用的模式。基於健康風險的整治是管理污染場址的另一種方法。健康風險評估結合傳輸模式和健康風險評估工具來計算地下水污染對人類健康的影響。近年來，我們開發了幾個先進的多物種傳輸解析解模式發表於頂尖期刊。本計畫目標是開發一個軟體可用於評估地下水含氯化溶劑污染場址的MNA和健康風險。計畫完成三項重要工作。工項一開發場地管理模組，用於管理和空間繪製有關地質、水文和污染的場址資料以及建立概念場址模型(CSM)。工項二開發MNA評估模組，主要是藉由於我們先進的多物種傳輸解析解模式的 FORTRAN 執行檔配備了互動式圖形使用者介面 (GUI)。工項三建立健康風險評估模組，將我們的先進多物種傳輸解析解模式與健康風險模式結合，用於計算致癌和非致癌健康風險。新開發的軟體將為評估 MNA 和健康風險的有效工具。
計畫英文摘要	Groundwater contamination by chlorinated solvents poses a significant environmental challenge worldwide, as these solvents are recognized carcinogens and toxicants, even at low concentrations. The remediation of such contamination is particularly difficult due to the presence of dense non-aqueous phase liquids (DNAPLs), which release chlorinated solvents into groundwater systems. Monitored Natural Attenuation (MNA) refers to the natural attenuation processes—encompassing physical, chemical, and biological mechanisms—that, under favorable conditions, act to reduce the mass, toxicity, mobility, volume, or concentration of contaminants without direct human intervention. For chlorinated solvent-contaminated sites, MNA is most effective when the natural processes facilitate the degradation and destruction of contaminants. The decision to implement MNA as a remediation strategy is supported by site-specific data and detailed analysis of contaminant behavior, necessitating long-term monitoring to evaluate the approach’s efficacy. Moreover, for MNA to be a viable strategy, it must ensure the protection of environmental safety and public health. Mathematical models play a crucial role in assessing the fate and transport of chlorinated solvents at contaminated sites. The formation and degradation of transformation products are key factors in contaminant transport processes. Multispecies transport analytical models, which solve simultaneous advection-dispersion equations coupled with first-order degradation reactions, have been developed to predict the transport of both the parent compounds and their daughter products. Among these, BIOCHLOR and REMChlor, developed by the USEPA, are commonly used for such assessments. In recent years, health risk-based remediation has emerged as an alternative approach to site management, integrating transport models with health risk assessment tools to evaluate the potential human health impacts of groundwater contamination. Building on this foundation, we have developed advanced multispecies transport analytical models, which have been published in leading scientific journals. This project aims to develop a comprehensive software package for the assessment of MNA and health risk at chlorinated solvent-contaminated groundwater sites. The project involves three key tasks: (1) the development of a site management module for managing and spatially mapping site-specific data related to geology, hydrology, contamination, and the conceptual site model (CSM); (2) the creation of an MNA assessment module that integrates our advanced multispecies transport analytical models into a user-friendly Graphical User Interface (GUI), utilizing FORTRAN executable files; and (3) the construction of a health risk assessment module that combines our multispecies transport models with health risk models to calculate both carcinogenic and non-carcinogenic health risks. The resulting software package offers an effective and comprehensive tool for the assessment of MNA and associated health risks at contaminated sites.
