Duke researchers identify tracking tool for fracking fluids

Duke University researchers said they have identified a new method to trace leaks and spills of fracking fluids by using a novel geochemical fingerprinting technology.

In a study published Monday, the six scientists write that they are the first to describe the tracer method, which can pinpoint highly diluted remnants of the industrial fluids in waterways and other drinking water sources.
