Subsurface RemediationEdition 1

Subsurface Remediation: Vadose Zones and Aquifers presents the state-of-the-art physical treatment methods for remediating contaminated subsurface formations, bridging theoretical foundations with practical applications through pedagogically enriched content. This book guides readers through the complex mechanics of water flow and solute transport in porous media, offering groundbreaking insights into dispersivity estimation methods. It also includes detailed examinations of inward hydraulic gradient sufficiency evaluation, degradation rate constant estimation methods with mass balance considerations, soil venting mechanics, and pump-and-treat technologies. With over 45 worked examples, end-of-chapter problems, and dual unit systems (SI and Imperial), this resource equips environmental engineers, hydrogeologists, and students with the essential knowledge to effectively remediate contaminated groundwater systems either by removing pollutants or by converting them into harmless products. It addresses contamination from industrial spills, agricultural chemicals, urban runoff, and landfill leachates.

• Provides in-depth coverage of widely used physical treatment methods including soil vapor extraction, bioventing, and pump-and-treat systems with real-world implementation guidance for environmental professionals.
• Contains the most current research and methodologies for estimating longitudinal, transverse horizontal, and transverse vertical dispersivity values.
• Includes end-of-chapter problems as well as a comprehensive solution manual for instructors.
