Mercyhurst's Dausey calls Pa. 'experimental fracking mecca'

“Pennsylvania has opened up its doors to fracking in ways that many other states in the U.S. have not,” said David Dausey, Ph.D., chair of the Mercyhurst University Public Health Department. “We don’t know enough about the environmental and human health effects of fracking and, as a result, Pennsylvania has become the home of experimental fracking.”

Dausey discusses his concerns in this month’s episode of The Dausey File: Public Health News Today.

Hydraulic fracturing or fracking is a controversial method to extract natural gas or petroleum from subterranean shale by using pressurized water to blast it open. Proponents of fracking have noted its potential for helping the U.S. achieve energy independence while also stimulating the economy and creating jobs. These proponents have met stiff resistance from environmental groups that claim fracking can result in air and water pollution and have adverse human health effects.

The discovery of Marcellus Shale coupled with Pennsylvania’s loose regulations and friendly relationship with the oil and gas industry have made it so that Pennsylvania has become a mecca for oil and gas industry interested in fracking, Dausey said.

He noted that the oil and gas industry along with the government have made it difficult, if not impossible, to conduct comprehensive scientific research on fracking. “Until we have real scientific research about the environmental and human health effects of fracking, we should regard all current fracking practices as experimental,” Dausey said. He posited that people who live close to fracking sites have “every right to be concerned” about the potential health consequences of fracking.

Chemicals used in the fracking process contaminate millions of gallons of water, Dausey explained. Safe disposal is an environmental concern. Further, he said, the exact chemicals used in the process are unknown because of industry resistance to surrender trade secrets. Fracking also has the potential to contaminate drinking water from wells.

“There is a recent lawsuit in Pennsylvania that claims that Pennsylvania officials didn’t report toxic chemicals found in drinking water near a gas drilling site,” said Dausey. “If true, this raises a real concern about how Pennsylvania is regulating and monitoring the fracking occurring in the state.”

Dausey noted that fracking isn’t just a water pollution concern. It can also deliver methane emissions into the air; the exact levels are disputed but research suggests that it may result in acute and chronic health problems for people living close to a well. Dausey urged further research before fracking becomes more widespread.

“Keeping the public safe should be our number one priority,” he said. “It should take priority over profits, over jobs, over everything.”

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
