4PLANET IMPACT / ISSUE

Untreated wastewater

Insufficiently treated municipal and industrial wastewater can contaminate freshwater, coastal systems and human environments.

Why it matters

Wastewater can be both a pollution source and a recoverable resource, but treatment needs vary by contaminant, system and receiving environment.

What the sources establish

UNEP's wastewater assessment identifies untreated wastewater as a major pollution challenge and evaluates opportunities for treatment, reuse and resource recovery.
