The urgent need for environmental remediation cannot be overlooked, as there is a rapid escalation in pollution, climate change, and ecosystem degradation. Industrial activities, agricultural practices, and urban development have significantly compromised the quality of water, air, and soil, posing severe risks to human health and biodiversity. Addressing these challenges requires innovative and sustainable solutions to restore and protect our natural resources. This book provides a comprehensive guide to the principles and practices of environmental remediation, with a particular focus on wastewater treatment, wetland restoration, and soil regeneration.
In this book, a wide range of topics essential for understanding and implementing environmental remediation strategies is covered. Dedicated sections cover important themes of wastewater treatment, wetland restoration, and soil regeneration. Each section provides an in-depth analysis of advanced technologies, sustainable practices, and innovative approaches tailored to address the specific challenges associated with each area. The discussions include both theoretical foundations and practical applications, ensuring a holistic understanding of the subject matter. Through detailed case studies and real-world examples, readers will gain insights into successful remediation projects and learn about the potential pitfalls and best practices in the field.
This book is designed for a diverse audience, including environmental scientists, engineers, policymakers, and students keen to explore environmental remediation. Readers will benefit from the comprehensive coverage of topics, gaining not only technical knowledge but also an appreciation of the socio-economic and regulatory dimensions of environmental remediation. Ultimately, this book serves as a vital resource for anyone committed to advancing the field of environmental sustainability and contributing to a healthier, more resilient planet.

Dr Prem Chandra Pandey is an Assistant Professor at Shiv Nadar Institution of Eminence, with more than 16 years of experience in geospatial technologies, natural resource monitoring, and environmental research.
