This book examines water quality control and management as a vital component of environmental protection, public health, and sustainable resource use. It explores the factors that influence water quality across natural and managed systems, highlighting the challenges posed by pollution, urbanisation, agricultural activities, and increasing demand for clean water. The text discusses methods used to evaluate and monitor water quality, illustrating how scientific assessment supports the identification of risks and the maintenance of safety standards. It also considers the operational and environmental challenges associated with water treatment and distribution systems, emphasising the need for effective management strategies in both rural and urban settings. Broader issues relating to water access, resource allocation, and responsible governance are examined, demonstrating how water quality management extends beyond technical control to include social, economic, and policy considerations. Through an integrated perspective, the book presents water management as a balance between environmental sustainability and human needs.

The book aims to provide readers with a practical understanding of water quality issues and management approaches, supporting informed decision-making in environmental protection, public health, and sustainable water-resource planning.
