Water is one of the precious and basic needs of life for all living beings and is a precious national asset. Without it, the existence of life cannot be imagined. Availability of pure water is decreasing day by day, and water scarcity has become a major problem that is faced by our society for the past few years. Hence, it is essential to find and disseminate the key solutions for water quality and scarcity issues. The inaccessibility and poor water quality continue to pose a major threat to human health worldwide. Around billions of people lacking to access drinkable water. The water contains the pathogenic impurities, which are responsible for water-borne diseases. The concept of water quality mainly depends on the chemical, physical, biological, and radiological measurement standards to evaluate the water quality and determine the concentration of all components and then to compare the results of this concentration with the purpose for which this water is used. Therefore, awareness and a firm grounding in water science are the primary needs of readers, professionals, and researchers working in this research area.

      This book explores the basic concepts and applications of water science. It provides an in-depth look at water pollutants’ classification, water recycling, qualitative and quantitative analysis, and efficient wastewater treatment methodologies. It also provides occurrence, human health risk assessment, strategies for removal of radionuclides, and pharmaceuticals in aquatic systems. The book chapters are written by leading researchers throughout the world. This book is an invaluable guide to students, professors, scientists, and R&D industrial specialists working in the field of environmental science, geoscience, water science, physics, and chemistry.

      Chapter 1 provides a general overview of different analytical methodologies that have been proposed for the analysis of phthalic acid esters in water samples. Special attention has been given to methods based on the application of sorbent-based microextraction techniques (i.e., solid-phase microextraction and micro solid-phase extraction magnetized or not, among others).

      Chapter 2 discusses the occurrence, dissemination, and behavior of pharmaceuticals in aquatic environments. Human exposure pathways and health risks, including the emergence of antimicrobial resistance are summarized. Risk factors promoting human exposure in developing countries are discussed. Methods for removal of pharmaceuticals and future research directions are also highlighted.

      Chapter 3 focuses on the latest developments in the methods for the oil/water separation through filtration of the membrane using distinct materials with surface properties that are super wetting.

      Chapter 4 presents the fundamental studies on the interdisciplinary issue of microplastic-based pollution of water environments; the scientific approach and roadmap to this complex problem are discussed.

      Chapter 5 summarizes the routes of formation of organic and inorganic chloramines upon chlorination disinfection. Chloramine’s possible health risks to humans including mutagenicity and hemolytic anemia are discussed. Further, the analytical methods for their control in aqueous environments are summarized. Selective methods including chromatographic and pH-controlled colorimetric techniques are highlighted.

Chapter 6 highlights the removal of industrial dyes using different approaches such as clay-based adsorbents, membrane filtration, and chemical treatment with special focus on clay-based low-cost adsorbents. The results of dyes’ adsorption study are discussed and compared with other reported wastewater treatment technologies.

      Chapter 7 provides a general description of biochar material from the preparation (synthetic methods) to its application as a powerful adsorbent in the wastewater treatment field. Recent advancements of biochar-supported materials with a focus on their applications for different contaminants’ removal and the underlying mechanisms are also discussed.

      Chapter 8 focuses on biological processes for swine wastewater treatment. Therefore, it details the swine wastewater characteristics, microorganisms, metabolic pathways involved, and biological processes in swine wastewater treatment. Besides, challenges and prospects in this research field are also presented.

      Chapter 9 discusses various imperative techniques to detect hazardous metal ions in various water reservoirs. The toxicological effects of various metal ions on living beings and atmosphere along with their detection limits, in addition to future perspectives of these procedures, are highlighted.

      Chapter 10 discusses the production of hydrogen-rich water and its role in medical applications. Firstly, a concise discussion of two of the production methods of hydrogen-rich water is provided. Lastly, the medical benefits, medical applications, and the safety of hydrogen-rich water are discussed in detail.

      Chapter 11 focuses on the application of hydrosulfide treatment in medicine, agriculture, and industry fields. Hydrosulfide anion is considered as an innovative gaseous signaling molecule and plays significant biological roles in the organisms. Its performance is discussed in detail for the improvement of biotic/abiotic stress tolerance of cells.

      Chapter 12 discusses the properties of available radionuclides including uranium, lead, polonium, cesium, strontium, thorium, radon, and radium. Moreover, the health problem caused due to these radionuclides contaminated water is also highlighted. Techniques involved in the removal of radionuclides including ion exchange, aeration, filtration, nanofiltration, and flocculation are summarized.

      Chapter 13 reviews the developing applications of membrane contactors in water treatment and desalination demonstrating their ability to substitute or supplement the conventional separation processes. The advantages and limitations of membrane contactors are discussed and their potential for value recovery from spent streams of small and medium
