Groundwater Contamination Transport Processes

Course Description

Welcome to "Groundwater Contamination Transport Processes," an advanced engineering course that delves into the fascinating world of underground water systems and their vulnerability to contamination. This comprehensive course offers a deep dive into the principles of transport in aquifers, equipping you with the knowledge and skills necessary to predict, plan, and manage the safe extraction of groundwater for both private and public use.

Groundwater is a crucial yet often overlooked freshwater resource, containing 1000 times more water than all lakes and rivers combined. With half of the world's population relying on groundwater for drinking, understanding its dynamics and protecting it from contamination is of paramount importance. This course will take you on a journey through the invisible underground world, exploring how human activities can affect water quality and how engineers can design solutions to treat and manage contaminated groundwater.
