Contaminants of Emerging Concerns and Reigning Removal Technologies (Paperback)

With an increased demand for wastewater reuse, groundwater recharge with treated wastewater has been practiced across the globe. As a result, groundwater quality deteriorates by emerging micropollutants from various anthropogenic origins, including untreated wastewater, seepage of landfill leachate, and runoff from agricultural lands. The fate of such emerging and geogenic contaminants in subsurface systems, especially in the groundwater, depends on several factors. Physicochemical properties of contaminants such as octanol-water partition coefficient, dissociation constant, water solubility, susceptibility to biodegradation under anaerobic conditions, and environmental persistence under diverse geological and pH conditions play a critical role during subsurface mass flow. Thus, advanced wastewater treatment techniques, followed by implementing stricter guidelines, are some of the measures that can safeguard water resources.

This book, in general, gives an understanding of the fate and mitigation strategies for emerging and geogenic contaminants in the groundwater. The first and second sections provide a detailed insight into various removal techniques and mitigation approaches. Possible treatment strategies, including bioremediation and natural attenuation, are also covered in those sections. Environmental assessment, groundwater vulnerability, health effects, and regulations pertaining to various contaminants are systematically presented in the third section.

Dr. Sanjeeb Mohapatra, after fishing his Ph.D. at the Environmental Science and Engineering Department, IIT Bombay, India, joined the Energy and Environmental Sustainability for Megacities (E2S2) program at National University of Singapore (NUS), Singapore, to pursue his postdoctoral degree. His research interest broadly covers the monitoring of emerging contaminants (ECs), photo-degradation and enzymatic degradation of ECs, and the role of dissolved organic matter in deciding the fate of such contaminants. He is a recipient of the Water Advanced Research Innovation (WARI) Fellowship awarded by the Department of Science and Technology (DST), India, University of Nebraska Lincoln, USA, Daugherty Water for Food Global Institute (DWFI), USA and Indo-U.S. Science and Technology Forum (IUSSTF). He is a recipient of the Newton-Bhabha Fellowship jointly awarded by DST, India, and the British Council, U.K. and the DST-INSPIRE fellowship awarded by DST, India. Dr. Mohapatra also won several international and local awards and has many publications in reputed journals, book chapters, and refereed conferences to his credit.
Dr. Kishor Acharya is a postdoctoral researcher at the School of Engineering, Newcastle University, UK, specialized in the field of public health engineering. His research interest varies from developing and applying portable molecular tools for on-site microbial hazard assessment to design novel techniques/methods for bio-remediation for removal of organic pollutants. Dr. Acharya is a recipient of the prestigious Rapid Response Grant award by the Global Challenges Academy to help the global dissemination of research skills and tools and capacity building among researchers of Nepal working in the WASH sector. Dr Acharya was recently endorsed as exceptional talent by the Royal Society. He has published his research work in leading environmental engineering journals such as Water Research and Environmental Science and Technology.
