地下環境分析模式在污染場址管理與整治實務工作中扮演許多關鍵角色，而水文地質概念模型則提供地下環境分析模式所需的水文地質資料。因此，為發展適用於台灣地區污染場址的地下環境分析模式，本計畫規劃並完成氣相污染物傳輸功能強化地下水流、生地化及熱傳核心模組且強化地下水流、生地化及熱傳核心模組之地下環境分析模式(二維HGC4.x/三維HGC5.x)、水文地質概念模型建立指引、地下環境分析模式整合使用者介面，並應用在一個示範場址進行模擬評估。 本計畫執行8個測試案例，包括含氯有機污染物、苯以及汞在地下水中遷移與擴散、吸脫附現象。其中，有6個二維測試案例及2個三維測試案例，每一個案例都廣泛考慮反應變化。6個二維案例有(1)TCE污染傳輸、(2)TCE生物整治、(3)苯污染傳輸、(4)採用Fenton化學氧化整治法對苯污染進行整治、(5)汞污泥傳輸、(6)汞蒸氣擴散傳輸。在案例(2)和案例(4)擴增為三維問題進行模擬。最後，利用本計畫所發展的地下環境模式平台與水文地質概念模型，應用在頭橋工業區示範場址，以乳酸為藥劑對TCE進行生物整治。所有結果顯示本計畫所發展的模式可適當展現情境現象。

Subsurface simulation models play key roles in the management and remediation of pollution sites. Geohydrology conceptual models provide hydrogeological information required by subsurface simulation models. In order to develop subsurface models which are applicable to Taiwan contaminated sites, this project is to enhance groundwater simulation models with gas diffusive transport capabilities and substantially modify core modules of subsurface flow, thermal transport, and reactive biogeochemical transport (2D HGC 4.X and 3D HGC 5.X). This project also establishes guidelines for constructing hydrogeological concept models and develop modeling platform and graphical users interface (GUI). The package developed in this project has been applied to simulate and evaluate a real site. Eight modeling examples were conducted in the project. These include investigating the transport, dispersion-diffusion, and adsorption-desorption of chlorinated organic contaminants, benzene, and mercury. Six cases are two-dimensional problems and two cases are three-dimensional problems. Extensive reaction networks for each case were considered. Six two dimensional problems are (1) transport of TCE, (2) bioremediation of TCE, (3) transport of Benzene, (4) chemical oxidation of Benzene with Fenton, (5) transport of mercury, and (6) diffusion of vapor mercury. Cases (2) and (4) were extended to three-dimensional problems. Finally, using subsurface modeling platform with graphical users interface (GUI) and enhanced geo-hydrologic conceptual model developed in this project, bioremediation of TCE with injection of lactate at Touciao industrial park has been demonstrated. All results show that the tools developed in this project can appropriately simulate the remediation phenomena.
