What does it take to unravel the complexity of aquifer heterogeneities in glacial deposits?
|Learn to recognize depositional environments, and their hydrogeologic implications during this landmark webinar series.|
Despite the validity about the challenges of aquifer heterogeneity and finding a meaningful solution through geologic principles, glacial deposits require additional attention to scale of depositional processes, stratigraphic unit definition, and post-depositional weathering effects.
For glacial deposits, aquitards play a major role in the ground water flow regime; but the secondary permeabilities originating from oxidation and weathering complicate ground water movement and can impact the hydraulic integrity of aquitards.
Plus, many field staff are simply not trained on identifying depositional environments or deciphering subsurface relationships from boring to boring. Boring log quality reflects staff skills about defining geologic units, unit correlation, geologic context leading to unit variability or uniformity, and environmental sequence stratigraphy.
If that's not daunting enough, multiple sequences from successive glacial advances or in contrast, glaciofluvial and glaciolacustrine depositional environments often lead to subsurface uncertainty at project completion.
This webinar series is designed to step you through the process of learning how depositional environments and post-depositional weathering impacts ground water movement and contaminant migration. The Series will demystify conventional wisdom about building Conceptual Site Models based solely on grain-size and associated matrix-permeabilities.
