Leana Hosea

Leana Hosea is the co‑founder of Watershed Investigations, an award‑winning environmental journalism nonprofit producing high‑impact investigations for major broadcasters and newsrooms. Watershed’s reporting has appeared across the BBC, the Guardian, ITV, Sky News, Al Jazeera, The Times and other leading outlets, and has helped expose the scale of PFAS contamination, industry disinformation, and the mounting cost of chemical cleanup as part of the Forever Pollution Project.

Combining data investigations, geospatial analysis, mapping, scientific collaboration and original environmental testing, Watershed uncovers systemic failures in pollution oversight and brings evidence directly to the public, policymakers and regulators.

Before co‑founding Watershed, Leana spent 18 years as a BBC radio and TV reporter, producer and shoot‑edit journalist, working across global news and the London investigations unit. She has produced and directed multiple TV and radio documentaries, both independently and through Watershed.
