The rate at which a volume of light non-aqueous phase liquid, such as oil, will flow through a unit width of porous material, such as soil, for a unit gradient is termed LNAPL transmissivity. Being able to measure LNAPL transmissivity is an important aspect of environmental assessment work. It is possible to measure LNAPL transmissivity via several methodologies (for example, baildown tests,…
