Methane Found in Well Water Near Fracking Sites
David C. Holzman

In a study of 68 private drinking water wells in northeastern Pennsylvania and New York, methane contamination rose sharply with proximity to natural gas drilling and hydraulic fracturing (“fracking”) sites.1 The average methane concentration in shallow groundwater in active drilling areas fell within the defined action level (> 10 mg/L but < 28 mg/L) for hazard mitigation recommended by the U.S. Department of the Interior, and the maximum (64 mg/L) was well beyond that threshold, according to the report. However, the researchers found no evidence of fracturing fluids. Principal investigator Robert B. Jackson of Duke University says fracking has been conducted in the sampled region since about 2008. The team sampled the water supplies in 2010.

The researchers measured concentrations of gases and certain isotopes of carbon in methane and other hydrocarbons to distinguish the ancient thermogenic gas stores sought in drilling operations from methane generated by microbial degradation of organic matter. The closer the well was to an active drilling site, the more likely it was the methane detected was thermogenic.

Flammable levels of natural gas are common in water supplies, and explosions—even reports of flammable drinking water—have occurred near fracking sites, says Abrahm Lustgarten, a reporter for Propublica who has investigated gas drilling across the United States. But no peer-reviewed studies have investigated health effects of chronic ingestion of small amounts of methane, Jackson says.2

Fracking done wrong has contaminated many water supplies.

Rapid expansion of natural gas development poses a threat to surface waters
Authors

Abstract
Extraction of natural gas from hard-to-reach reservoirs has expanded around the world and poses multiple environmental threats to surface waters. Improved drilling and extraction technology used to access low permeability natural gas requires millions of liters of water and a suite of chemicals that may be toxic to aquatic biota. There is growing concern among the scientific community and the general public that rapid and extensive natural gas development in the US could lead to degradation of natural resources. Gas wells are often close to surface waters that could be impacted by elevated sediment runoff from pipelines and roads, alteration of streamflow as a result of water extraction, and contamination from introduced chemicals or the resulting wastewater. However, the data required to fully understand these potential threats are currently lacking. Scientists therefore need to study the changes in ecosystem structure and function caused by natural gas extraction and to use such data to inform sound environmental policy.

This is not news.

Agree, anybody who has honestly researched the facts already knew this.

You should post those, because it appears this one is about surface water.

That study was in 2011, here is one from 2015-

What is true is that fracking waste water is prone to geo-thermal steam explosions because the boiling point of water increases with pressure so the hotter water at the bottom of the shaft rises create a steam explosion. This causes many small earthquakes that in turn reduces the probability of big earth quakes.

Now Willy, do you know how the Richter scale works?

Richter magnitude scale - Wikipedia

As measured with a seismometer, an earthquake that registers 5.0 on the Richter scale has a shaking amplitude 10 times greater than an earthquake that registered 4.0 at the same distance. As energy release is generally proportional to the shaking amplitude raised to the 3/2 power, an increase of 1 magnitude corresponds to a release of energy 31.6 times that released by the lesser earthquake.[1] This means that, for instance, an earthquake of magnitude 5 releases 31.6 times as much energy as an earthquake of magnitude 4

So, a move of 2, like 3 to 5, on that scale represents over 900 times more energy. So to relieve a 5, there would have to be over 900 3's. The small quakes simply don't release enough energy to affect the strains that cause a large quake.

I wouldn't believe much coming from Duke.

too centrist for you?

Good...so to Libtards can we now call this "settled science?"
