PRINCIPLES OF FLOW, TRANSPORT AND REMEDIATION OF POLLUTANTS IN UNDERGROUND WATERS
25 de November de 2019 - 08:00 - 17:00
INTRODUCTION:
Groundwater is an essential water resource and preserving its quality is a growing concern around the world. Therefore, many governments have passed strict regulations to protect groundwater quality and to clean up currently polluted aquifers.
These laws and regulations affect all sources of groundwater pollution, including mining practices, chemical industries, gas stations, industrial landfills, refineries, municipal and private solid waste activities, and pesticide agricultural practices. and / or fertilizers to prevent groundwater contamination.
OBJECTIVES:
Acquire a broad practical knowledge of the concepts, principles, and professional practices underlying hydrology, flow and transport of contaminants, contamination, and groundwater remediation.
Show participants the design and analysis of pumping tests as well as application methods for determining hydraulic conductivity, storage coefficient, porosity, and recharge. The objective of this course is to provide participants with the knowledge necessary to use the numerical tools for modeling the flow and transport of pollutants in water
Underground, with special emphasis on the practical application of skills development in Visual MODFLOW, BIOSCREEN, and AquiferTest to simulate applications in groundwater hydrology, contamination, and remediation.
TEMARY:
Basic to advanced principles in underground hydrology.
Basic to advanced principles in groundwater contamination and remediation.
Fundamental concepts of flow and transport of pollutants in Groundwater.
Design and analysis of pumping tests, application of “slug test” methods using AquiferTest software. Methods for determining hydraulic conductivity, storage coefficient, porosity, and recharge.
Concepts and advanced principles of groundwater flow, destination and transport of pollutants and natural attenuation: diffusion, dispersion, sorption, retardation, biodegradation, reduction or depletion of the natural source zone.
Cleanup goals or targets, key regulators, and risk controllers for remediation.
LNAPLs (Light Non-Aqueous Phase Liquids, BTEX, MTBE), DNAPLs (Dense Non-Aqueous Phase Liquids): concepts, remediation and challenges.
Introduction to popular software programs (eg MODFLOW, MT3D, BIOSCREEN…) and their applications in groundwater hydrology, pollution and remediation: Emphasis on practical applications.
Fundamental concepts and theory of water and chemical movement in the unsaturated zone; Laboratory methods and field equipment (suction lysimeters and tensiometers) to characterize the extraction of water samples from the soil / gases in the unsaturated zone (Gases in the Vadose Zone)
