Watershed Investigations is an independent, not‑for‑profit environmental journalism unit that investigates and reports on water‑ and pollution‑related issues across the UK and beyond, focusing on freshwater, marine, waste, chemicals and broader ecological risks.

Founded by environmental journalists including Rachel Salvidge and Leana Hosea, Watershed aims to fill a gap — bringing rigorous, evidence‑based investigations into water scarcity, pollution, chemical contamination (such as PFAS “forever chemicals”), sewage dumping, biodiversity loss and the impacts of climate change on water resources.

Their work is regularly published in major UK media outlets and sometimes in collaboration with them, intended not only to expose environmental and public‑health hazards, but also to influence public awareness, policy debates and accountability for pollution and mismanagement.
