Sacred River Poisoned by Illegal Gold Mining
3 Sep
Summary
- Toxic metals contaminate the Osun River during annual festival.
- Illegal mining upstream is causing severe environmental damage.
- Devotees risk health by drinking polluted water for blessings.

The Osun River, central to Nigeria's annual Osun Osogbo festival and a UNESCO World Heritage site, is critically polluted. For centuries, devotees have gathered to seek healing and blessings from the Yoruba goddess Osun, using the river's water. However, since 2018, mining operations upstream have introduced toxic heavy metals and sediment, turning the once-clear water brown.
Despite tests confirming dangerous levels of lead, mercury, and cyanide, many worshippers continue to drink the water, believing the goddess offers protection. Activists launched a #SaveOsunRiver campaign and authorities have arrested prospectors, but no comprehensive remediation plan or measurable improvement has been achieved. This contamination poses significant risks to public health, aquatic biodiversity, and the continuity of this ancient cultural practice.
