The pollution of groundwater and soil by hydrocarbons is a significant and growing global problem. Efforts to mitigate and minimise pollution risks are often based on modelling. Modelling-based solutions for prediction and control play a critical role in preserving dwindling water resources and facilitating remediation. The objectives of this article are to: (i) to provide a concise overview of the mechanisms that influence the migration of hydrocarbons in groundwater and to improve the understanding of the processes that affect contamination levels, (ii) to compile the most commonly used models to simulate the migration and fate of hydrocarbons in the subsurface; and (iii) to evaluate these solutions in terms of their functionality, limitations, and requirements. The aim of this article is to enable potential users to make an informed decision regarding the modelling approaches (deterministic, stochastic, and hybrid) and to match their expectations with the characteristics of the models. The review of 11 1D screening models, 18 deterministic models, 7 stochastic tools, and machine learning experiments aimed at modelling hydrocarbon migration in the subsurface should provide a solid basis for understanding the capabilities of each method and their potential applications.

We present analytical solutions for transport with bimolecular reactions in a single fracture embedded within an infinite rock matrix. The fracture and matrix are initially assumed to contain one aqueous species (B) at a uniform concentration. A second aqueous species (A) is injected into the fracture and reacts with B and an additional immobile species (N) in the rock matrix. Under these conditions, moving reaction fronts form and propagate along the fracture and into the rock matrix. We employ a composite similarity variable involving two space variables to derive analytical solutions for all species concentrations and the geometry of reaction fronts in the fracture and matrix. The behavior of the reaction‐diffusion equations in the rock matrix is posed as a Stefan problem. For uniform advection in the fracture, our analytical solutions establish that the reaction fronts propagate as the square root of time in both the matrix and the fracture. Our analytical solutions agree very well with numerical simulations. We extend our analytical solutions to nonuniform flows in the fracture by invoking a travel‐time transformation. We present applications of our analytical solutions to in situ chemical oxidation of dense nonaqueous phase liquids in fractured rock, wherein an oxidant (A, e.g., permanganate) is injected through fractures and consumed by bimolecular reactions with dissolved dense nonaqueous phase liquids (B, e.g., trichloroethylene) and natural organic matter (N) in the fracture and rock matrix. Our analytical solutions are also relevant to a broad class of reactive transport problems in fracture‐matrix systems where moving reaction fronts occur.
