Environmental Health News reporter Kristina Marusic gives the story behind "Fractured," an investigation of fracking pollution in western Pennsylvania.

The series, published this week, reveals alarming evidence of toxic industrial chemicals linked to drilling operations in the urine of families living near fracking operations. Marusic spearheaded the investigation by collecting urine, air, and water samples from five southwestern Pennsylvania households. Her work represents the first time families in western Pennsylvania have been tested for exposure to chemicals emitted from fracking operations.

In addition to the pollution exposure, the series exposed a regulatory system that favors oil and gas development at the expense of residents' mental, physical, and social well-being.

"I hope these families will be able to use this data to better advocate for their own health with their political representatives, and their doctors, and their community leaders," she said.
