Camp Lejeune is a vast US Marine Corps base in North Carolina. It’s been in operation since the 1940s and covers a massive 240 square miles. But for years it hid a secret. For decades, its water supply was contaminated with harmful chemicals found to increase the risk of some cancers. It’s estimated that one million people might have been exposed to the toxic water. But it wasn’t just American personnel who were based at Camp Lejeune. Soldiers from all over the world - including from the UK - also spent time there on training exercises and exchange programmes. Emma Forde hears from the British veterans and their families who lived and worked on the base and have since suffered serious health problems or seen loved ones die from conditions associated with exposure to the water. But despite a compensation scheme for victims being widely reported in the US, there are concerns that those from the UK are still unaware of the serious health risks they were exposed to. And time is running out.
