Assessments and case studies on water quality and water pollution in different regions and countries, including assessment of emerging pollutants (pharmaceuticals and microplastics)
WHO monitors safe treatment of wastewater through the Integrated Monitoring Initiative and the enabling environment for improvements in wastewater treatment and safe use through the UN-Water global analysis and assessment of sanitation and drinking-water (GLAAS). WHO also supports global progress towards improvements in treatment and safe use through the WHO Guidelines on Safe Use of Wastewater in Agriculture and Aquaculture and Guidelines on Safe Recreational Water Environments and promotion and capacity building on sanitation safety planning business models for safe resource recovery and reuse.
WHO also interfaces with health programmes where wastewater and ambient water quality plays a key role on primary prevention especially antimicrobial resistance and food safety.
