Fast semi-analytical approach to approximate plumes of dissolved redox-reactive pollutants in heterogeneous aquifers. 2: Chlorinated ethenes

► The approach combines specific particle tracking with chemical reactions. ► The superposition principle is extended to series of redox reactions. ► Several examples of chlorinated solvents reactions compare well with the numerical model. ► The calculation times is 100 to thousands of time faster than numerical models (RT3D, PHT3D, PHAST).
