The first edition of Bioanalytical Tools in Water Quality Assessment was released in 2012. The field has exploded since and the second edition updates and reviews the application of bioanalytical tools for water quality assessment including surveillance monitoring. The book focuses on applications to water quality assessment ranging from wastewater to drinking water, including recycled water, as well as treatment processes and advanced water treatment. Emerging applications for other environmental matrices are also included. Bioanalytical Tools in Water Quality Assessment, Second Edition, not only demonstrates applications but also fills in the background knowledge in toxicology/ecotoxicology needed to appreciate these applications. Each chapter summarises fundamental material in a targeted way so that information can be applied to better understand the use of bioanalytical tools in water quality assessment. The book can be used by lecturers teaching academic and professional courses and also by risk assessors, regulators, experts, consultants, researchers and managers working in the water sector. It can also be a reference manual for environmental engineers, analytical chemists and toxicologists. ISBN: 9781789061970 (Paperback) ISBN: 9781789061987 (eBook)

Raw Water Quality

Raw water quality variation has a great effect on drinking water treatment. To improve the adaptivity of drinking water treatment and stabilize the quality of treated water, a raw water quality assessment method, which is based upon the support vector machine (SVM), is developed in this study. Compared to existing raw water quality assessment methods, the assessment method studied herein is oriented to drinking water treatment and can directly be used for the control of the chemical (alum and ozone) dosing process. To this end, based upon the productive experiences and the analysis of the operating data of water supply, a raw water quality assessment standard oriented to drinking water treatment is proposed. A raw water quality model is set up to assess the raw water quality based upon the SVM technique. Based upon the raw water quality assessment results, a feedforward–feedback control scheme has been designed for the chemical dosing process control of drinking water treatment. Thus, the chemical dosage can be adjusted in time to cope with raw water quality variations and hence, the quality of the treated water is stabilized. Experimental results demonstrate the improved effectiveness of the proposed method of raw water quality assessment and the feedforward–feedback control scheme.

The quality of Klang river water is deteriorating dramatically since it is in urban places every day and become one of the major problems.  Therefore, the Malaysian government had initiated one river cleaning project named River of Life (ROL) project. This project is for rehabilitating and restoring the Klang river. A series of river water treatment plant (RWTP)s have been operated in Klang river catchment since 2014. Six RWTPs station has been monitored up to eight stations until presents. Eight parameters consisting of physio-chemical types and biological types have been recorded. RWTP effluent discharges are targeted to achieve Malaysia Interim National Water Quality Standard (INWQS) under Class II B. Since previous RWTP performance only emphasized on local river pollutants and certain conditions, this paper will investigate the effectiveness of full-scale RWTP unit process for river condition. Water quality assessment are involved which are consist of effluent water quality monitoring and pollutant removal efficiency. Most of the major pollutants able to be reduced by more than 50% reduction. Although BOD and AN still not able to achieve standard range gazetted by INWQS Class IIB, there is an improvement of river water quality at Klang River by using IFAS technology adopted in the RWTP system.

Background and Aim: A population of endangered sitatunga antelope (Tragelaphus spekii) lives in a free-range environment at Impala Sanctuary in Kisumu, Kenya. Kenya Wildlife Service park officials suspected that increased demands on outdated sewage infrastructure caused animal drinking water sources to become contaminated which resulted in animal sickness and death. In this study, we complete a water quality assessment on open water sources within the park boundaries to determine if water was suitable for animal consumption. Materials and Methods: For the assessment of water, we measure eight physical and chemical parameters (pH, temperature, fecal coliform, dissolved oxygen, biochemical oxygen demand, nitrates, total phosphates, and turbidity). These eight parameters were chosen because they are used to establish a water quality index (WQI) percentage which proved to be useful to communicate conditions to park rangers, stakeholders, and adjacent landowners. Results: Through 6 months of assessments, data collection, and analysis, we determined that most open water sources are severely contaminated, ranking on the WQI from 46% to 58% (bad to medium). In addition, we compared our data to drinking water standards set by the U.S. Department of Agriculture for livestock to find that only two sites met the minimum criteria. The remaining four sites were exponentially contaminated with levels reaching 10× recommended values for animal health. Conclusion: Following these findings, the park was able to attract money for sewage infrastructure rebuilds that resolved the contamination problems. Sickness and death of free-roaming animals, including the antelope, were reduced.
