CANONSBURG (KDKA) — Many attending a hearing at the Canonsburg Middle School are fearing an increase in the cancer rate in the Canon-MacMillan School District and that it may be a side effect of fracking.

So far, there’s no evidence that fracking is linked to cancer, but many in Washington County fear the oil and gas industry.

Fracking is a method of injecting liquid at high pressure into rocks and extracting oil or gas. The fear is that the wastewater from this process is contaminating the water supply with toxic chemicals. There’s no clear link between cancer and fracking, but the community points to six cases of a rare cancer, Ewing Sarcoma, being diagnosed in the past decade at the Canon-MacMillan School District.

This includes one woman who’s brother didn’t survive.

“I don’t want kids or anybody being potentially poisoned for someone else’s pocket money,” said Carla Marratto-Cumming of the Environmental Health Project.
