LONDON: Fifteen British servicemen who worked on a carcinogen-contaminated water treatment site during the Iraq war say they were not offered biological screening despite official guidance saying they should have been.

The former Royal Air Force members, who have suffered from ailments including cancer, tumors and nosebleeds, told Sky News they were offered no medical assistance or subsequent treatment after having been exposed to toxic sodium dichromate at the Qarmat Ali water treatment plant in 2003.

The channel said it had seen a letter from the RAF’s medical authority stating that senior officers knew of the dangers posed by the substance.

Peter Lewis, 53, was one of 88 personnel deployed to guard the site, which was deemed vital for getting Iraq’s oil industry up and running. He told Sky: “I’ve had eight or nine operations to remove cancer.

“I’ve had so many lumps taken out of my neck, one on my face. This is something I’m literally fighting every year now. It’s constant.”
