High levels of radioactivity persist in Pennsylvania stream sediments 7 years after fracking wastewater disposal was restricted

Three wastewater disposal sites in western Pennsylvania have been analyzed to contain as much as 650 times higher radioactive sediments than unaffected sites upstream. These numbers are made even more shocking considering that more than seven years have passed since Pennsylvania’s government restricted the disposal of fracking wastewater into these sites. Authors of the new […]

Earthquakes in Oklahoma are manmade, strongly linked to fracking wastewater injection: Study

Man-made earthquakes in Oklahoma are strongly linked to fracking methods such as the injection depth of wastewater, according to a major study published in Science. The study aimed to provide targeted evidence in proving that there has been a substantial decrease in induced seismicity in the Oklahoma region, with possible applications in other parts of the […]

Fracking wastewater found to contaminate lakes

Hydraulic fracturing, more commonly known as fracking, is an unconventional method of extracting oil and gas. The practice has paved the way for increased production of domestic oil and gas in the United States. According to the U.S. Energy Information Administration, fracking now accounts for more than one-half of oil production and two-thirds of gas production across the country. Fracking’s […]

Pennsylvania: New report reveals that fracking has caused a large increase in earthquakes

Earthquakes are a rare event in a tectonically peaceful region like Pennsylvania. However, fracking operations triggered a series of small shivers that took place last year, state officials of the Department of Environmental Protection (DEP) announced in a recent report. While they were too weak to be felt by humans (they ranged from 1.8 to […]
