Emerging Contaminants and Water Conservation

The expanding global population and limited water supplies make water conservation more crucial, as water and human health are threatened by pollutants. This chapter examines emerging contaminants and water conservation practices, including their causes, effects, and controls, as both point and non-point sources pollute surface, ground, and drinking water. Conventional wastewater treatment plants struggle to remove new pollutants, making management difficult; manufacturing and mining emit chemicals into rivers, while flame retardants and plasticizers do too, impairing endocrine, neurological, and immunological systems in humans and the environment. The chapter also delves into pharmaceutical, personal care, plasticizer, and pesticide new pollutants, their origins, properties, and consequences. Water conservation and developing pollutant management are advantageous through rainfall collection, water reuse, and water-efficient fixtures to minimise freshwater demand and pollution. Source control, treatment, monitoring, and regulation represent new pollution management methods, boosting health and sustainability. Source mitigation, advanced treatment, and synergistic water conservation are needed to address growing pollutants and water scarcity, stressing the necessity for coordinated efforts to safeguard safe and sustainable water resources for future generations.
