TMVOC是专为研究地下污染的挥发性有机化合物（VOCs），如碳氢化合物燃料和工业溶剂。它可以模拟非水相液体（NAPLs）通过非饱和带和饱和带的一维、二维或三维迁移，在地下水位上形成油透镜，地下水中VOCs的溶解和随后的运移，以及VOCs在非饱和带间隙空气中的汽化和迁移，以及VOCs在多孔介质岩石基质上的可逆吸附。TMVOC解释了NAPL中可能存在的不同VOCs的水溶性和挥发性差异。热修复处理，如蒸汽注入或电阻加热以及相关的相变和流动效应也可以建模。还包括一个简单的生物降解半衰期模型。
TMVOC is designed for studying subsurface contamination by volatile organic compounds (VOCs), such as hydrocarbon fuels and industrial solvents. It can model the one-, two-, or three-dimensional migration of non-aqueous phase liquids (NAPLs) through the unsaturated and saturated zones, the formation of an oil lens on the water table, the dissolution and subsequent transport of VOCs in groundwater, as well as the vaporization and migration of VOCs in the interstitial air of the unsaturated zone, and the reversible sorption of VOCs on the rock matrix of a porous medium. TMVOC accounts for differences in aqueous solubility and volatility of different VOCs that may be present in a NAPL. Thermal remediation treatments such as steam injection or electric resistance heating and associated phase change and flow effects can also be modeled. A simple half-life model for biodegradation is included as well.
