Tracing The Culprit When Fracking Pollutes Water Supplies

Lead in text: 
Several research teams have developed techniques like adding tiny fragments of rust (iron oxide) or synthetic DNA to the drilling fluid to make it easier to identify what drilling rig is responsible for contamination. This practice could help produce hard evidence in cases that are brought to court over natural gas drilling practices.
Scientists are developing ways to add non-toxic tracers to drilling fluid so if groundwater is contaminated, investigators would be able to pinpoint if an oil or gas drilling operation was to blame.
