Most do. You can tell a lot about the health of your population by testing wastewater. Hell they can detect levels of albuterol, the medicine in asthma inhalers, to correlate with increases in air pollution. WHO has global programs for this, and the majority of countries treat their wastewater already, so it’s not a huge leap to run some tests on it.
Reporting on industrial wastewater treatment remains limited, with data only reported from 22 countries representing 8 per cent of the global population. In these countries, only 38 per cent of industrial wastewater was reported as treated, and only 27 per cent was safely treated.
