Fate and transport of LNAPLs under fluctuating water table conditions Academic Article uri icon

abstract

  • A mathematical model is presented to simulate fate and transport of lighter-than-water NAPLs (LNAPLs) in the region (known as smear zone) subjected to fluctuating water table conditions. The model considers the presence of discontinuous ganglia in the smear zone, and accounts for biodegradation and dissolution from both the ganglia and the pool. Mass loss from the saturated part of the smear zone is calculated for a hypothetical scenario to demonstrate the effect of fluctuating water table conditions. In general, fluctuating water table conditions increase the mass loss. The concentration profile in the smear zone and the mass loss are governed by the rate of fluctuations and the life span of ganglia.
