This volume offers detailed information on the behaviour of various water pollutants, and on the principles and concepts of groundwater flow and transport. It will help readers to understand and execute the planning, supervision, and review of solute transport and groundwater modeling projects. The book also discusses the role and fate of elements that have been identified as major contaminants in surface and subsurface waters, and their adverse effects on ecology and human health. The book explores this theme throughout four sections a. Understanding Soil-Water Systems, b. Fate and Transport of Pollutants, c. Physico-Chemical Treatment of Wastewater and d. Microbial Techniques Used to Decontaminate Soil-Water Systems. Introducing readers to a range of recent advances concerning the fundamentals of subsurface water treatment, it offers a valuable guide for teachers, researchers, policymakers, and undergraduate and graduate students of hydrology, environmental microbiology, biotechnology and the environmental sciences. It also provides field engineers and industrial practitioners with essential support in the effective remediation and management of polluted sites.

Elucidates on behavior and fate of several pollutants in subsurface water Examines suitable remediation techniques to decontaminate polluted sites Offers detailed case studies related to the fate and transport of different subsurface pollutants using multi-scale laboratory and numerical modeling

Dr. Pankaj Kumar Gupta has been a postdoctoral fellow at the Faculty of Environment, University of Waterloo since January 2019. The majority of his works focus on two areas: (1) understanding the occurrence of bio-geo-chemical interactions when pollutants migrate into groundwater systems; and (2) developing remediation strategies. He received his Ph.D. from the Department of Hydrology, Indian Institute of Technology Roorkee with a dissertation on "Fate and transport of LNAPL under varying subsurface conditions". He has received an AGU Student Travel Grant (2017), JPGU Travel Grant (2018), and EXCEED-SWINDON & DAAD Germany Grant (2018). He serves as an editorial board member for SN Applied Sciences *and *Frontiers in Water. He has published 15+ research papers, ~20 book chapters, and two popular science articles. He has reviewed several research articles for reputed journals including RSC Advances, Groundwater for Sustainable Development,ASCE JEE, ASCE Irrigation and Drainage, Env. Sc, Pollution Research, Ecohydrology, J. of Contaminant Hydrology etc. Further, he has led many site restoration and remediation consultancy projects at polluted industrial sites in India.
