An Overview of Emerging Contaminants in Water Sources A Global Outlook | Book Publisher International

 Advance in methods of detection for some organic chemicals in water sources has steered the screening and quantification of high quantity of contaminants collectively with their end products, which formerly were not identified in water sources and are currently recognized as emerging contaminants. The accumulation and discovery of levels of these emerging contaminants in water sources has reduced water quality and made it risky for aquatic and human life. Exposure to these organic contaminants may trigger serious health effects. The aim of this book is to give a comprehensive review of global occurrence of emerging contaminants in various water sources such as surface water, groundwater, treated drinking water and wastewater influent and effluent. The book introduces audience to concepts of water sources, emerging contaminants, point sources and non-point sources of emerging contaminants. It offers a glimpse of international and South African case studies on the occurrence of emerging contaminants precisely herbicides, pharmaceutical, steroid hormones and personal care products in water sources as well as in wastewater treatment works. The analytical and removal methods of emerging contaminants in water sources are also covered. Moreover, information on possible environmental health impacts ensuing from exposure to emerging contaminants and their possible mitigation measures (such as classification and labelling methods; point source separation methods; regulating the release of emerging contaminants) are discussed. The occurrence of emerging contaminants around the world (Africa, America, Asia, Europe, and Oceania) is likely to upsurge in water sources and wastewater treatment works as a results of rise in population which is a public health concern. Therefore, more studies that report on the widespread of emerging contaminants in water sources, and their associated environmental health risks are needed to help regulators in establishing priority measures for management of water resources.

Drinking Water Quality Assessment Using Water Quality Index in Ado-Ekiti and Environs, Nigeria | Chapter 10 | Challenges and Advances in Chemical Science Vol. 1

 Water quality is a description of water's chemical, physical, and biological properties in relation to its intended use(s) and a set of standards. Water quality has deteriorated as a result of pollution from both point and non-point sources. As a result, any specific source's water quality can be investigated using physical, chemical, and/or microbiological parameters. The term water quality index (WQI), which is a rating reflecting the composite influence of different water quality parameters, is one of the most effective tools for communicating information on water quality. The Water Quality Index (WQI) provides a single number that expresses the overall water quality at a specific location. Nigeria employs the Water Quality Index (WQI). Between January and August 2014, researchers at the Department of Microbiology at Ekiti State University in Ado-Ekiti, Ekiti State, Nigeria, used an experimental study design. Among several developed water quality indices, the study used the Weighted Arithmetic Water Quality Index (WAWQI) method, which categorizes water quality based on purity. The WAWQI was calculated using physicochemical parameters such as pH, total dissolved solids, turbidity, total hardness, calcium, magnesium, sulphate, chloride, and nitrate. Standard methods were used to determine the parameters. The calculated WAWQI values for borehole, stream, pipe-borne, well, spring, and packaged water samples were 54.16, 65.12, 67.46, 56.29, 46.08, and 49.59, respectively. This result indicates that the analyzed water samples from various sources had poor water quality, with the exception of spring and packaged water samples, which have good physico-chemical qualities and are thus safe for human consumption.
