DNAPL Lagoon Drainage and Subsequent Migration examined via Numerical Modelling.

For two decades groundwater contaminants, specifically dense non-aqueous phase liquids (DNAPLs), were disposed and stored in lagoons in relatively impermeable soils. However, due the heterogeneous nature of the subsurface, DNAPLs leaked through to the subsurface from the storage lagoons. This investigation aims to determine the timescales of DNAPL lagoon drainage into the subsurface and the time required for the leaked DNAPL to stop migrating. DNAPL3D, a published numerical model, will be used in a series of simulations to analyze the drainage and migration of DNAPLs from a lagoon. As an extension of the DNAPL3D model, the project will expand the current understanding of DNAPL migration as well as offer real field applicability as it could provide insight into the subsurface condition of sites previously commissioned as DNAPL storage lagoons.
