High levels of radiation -- up to 60 times higher than the maximum allowed in drinking water -- have been reported in a stream feeding into the drinking water of hundreds of thousands of people in western Pennsylvania including Pittsburgh.

"It's highly suggestive that it may be due to drilling operations, or at least the waste water."

“Radium does not go away quickly. The half-life for radium 226 is 1,600 years, meaning even then it will still be half as potent at it is today ... and can cause bone, liver and breast cancer."

"In 2014, the Izaak Walton League, a respected national conservation group, had been monitoring Ten Mile Creek in Greene County, PA. They found something in the creek that should not be there - radioactive levels of radium-226 and radium-228. 19 times higher than what federal drinking water standards allow, and 65 times higher upstream!
"The the Izaak Walton League had to badger PA DEP to affirm its findings. The DEP finally did confirm what they found. The DEP would not release the information. The Izaack Walton League had to force the DEP to do so. Now, that the cat's out of the bag, the DEP has announced yet another investigation.
"Long-term exposure to radium increases the risk of developing several diseases. Inhaled or ingested, radium increases the risk of developing such diseases as lymphoma, bone cancer, and diseases that affect the formation of blood, such as leukemia and aplastic anemia. These effects usually take years to develop. External exposure to radium's gamma radiation increases the risk of cancer to varying degrees in all tissues and organs.
"In the meantime, the fracking goes on and the radioactive creek flows to our drinking water sources. Radioactive waste is not associated with coal mining - it is associated with fracking. This is an unacceptable risk to everyone's health, welfare and safety!
"The mission of the PA DEP is to: '...protect Pennsylvania's air, land and water from pollution and to provide for the health and safety of its citizens through a cleaner environment. We will work as partners with individuals, organizations, governments and businesses to prevent pollution and restore our natural resources.' ABIDE BY THE MISSION!

"THIS NOT THE FIRST RADIOACTIVE CREEK IN PA!

"Dufalla suspects malfeasance. He thinks someone dumped fracking waste in the Clyde Mine....
"Dufalla points out illegal dumping has occurred in this part of the state before. In 2012, a local business man pleaded guilty to illegally dumping fracking waste, into streams, ponds, and an abandoned mine.
"And last year, a local sewer authority announced it was investigating possible dumping of frack water at its treatment plant."
