Emerging Pollutants in Wastewater: A Challenge for Water Reuse
Summary
This review examines emerging pollutants in wastewater as a central challenge for water reuse strategies, covering contaminants present at both domestic and industrial scales. It evaluates the sustainability benefits and treatment hurdles associated with recycling wastewater to address global water scarcity.
Although water represents two-third of our planet, we are facing a serious water shortage. The water crisis is the most pervasive, serious and invisible dimension of the earth's ecological devastation. Wastewater reuse has been considered as a promising solution to cope with the problem of water deficiency around the word. Both at the domestic and industrial levels, recycling and reuse of wastewater could have several sustainable benefits. The recycled water can be reused in the original process, reused in another process, or used in another sector or application. The implementation of wastewater reuse should take into account all the various types of affected stakeholders, accounting in addition for the external costs and benefits derived from the reuse decision. The objective of this chapter is to analyze the potential of wastewater reuse mainly for agricultural purposes stressing the toxicological aspects due to the potential presence of contaminants in these waters.

Insights into Global Water Reuse Opportunities
This review examines global opportunities and challenges for reusing treated wastewater, which is becoming increasingly important as water scarcity worsens worldwide. A key concern discussed is that recycled water may contain emerging contaminants including microplastics that current treatment methods do not fully remove. The findings highlight the need for advanced treatment technologies to ensure that water reuse does not become a pathway for microplastic exposure in communities.
