There will be a seminar on Friday, January 17, 2020, at 2:00 pm (8:00 LT) on “COMMON SUBSURFACE CONTAMINATION SCENARIOS AND THEIR ANALYSES” by Prof. Hilary I. Inyang.
venue : BIT Seminar room
Anthropogenic sources of subsurface soil and groundwater contamination are numerous. Among them are gasoline storage tanks, waste landfills, wastewater impoundments, waste injection wells, septic tanks and surface waste heaps. From these facilities, contaminants typically leach into the ground and travel there in, under physical and chemical gradients. The fate and transport of such contaminants can be quantitatively described using knowledge of sorption and desorption processes of the contaminants with the transport media (geomaterials), the textural characteristics of the geomedia, the degree of saturation of the geomedia with fluids, and the environmental conditions of the contaminant/geomedia interactions as defined by the environmental pH, Eh and temperature. In this lecture, fundamental mathematical formulations for tracking the transport of contaminants in the subsurface will be analyzed.
