CSIs now have a new tool in their belt: the chemical signatures left by local drinking water in human hair.
Scientists at the University of Utah have found that the ratios of different forms of hydrogen and oxygen in local drinking water vary from region to region across the country. These elements are incorporated into the hair as it grows. Traces in the hair can show where a person has recently lived or traveled, and could help police track the recent movements of criminals.
"You are what you drink - and that is recorded in your hair," said lead researcher Thure Cerling.
