First risk assessment of shale gas fracking to biodiversity

A recent study published in Annals of the New York Academy of Sciences explores the threat posed by shale gas fracking to biodiversity. The research reveals potential impacts on ecosystems, including salinization of soils, surface waters, and fragmentation of forests.

Many stressors associated with fracking due to perceived lack of trust, Pitt finds

A University of Pittsburgh study found that fracking is associated with stress and various health concerns in Pennsylvania residents. The survey of 33 participants revealed that stress was the most commonly cited concern, with many reporting feelings of being taken advantage of or misled by the gas drilling industry.

Analysis of fracking wastewater yields some surprises

Hydraulically fractured natural gas wells in the Marcellus shale region produce about 35% as much wastewater per unit of gas recovered as conventional wells. The total amount of wastewater has increased by 570% since 2004, threatening to overwhelm the region's wastewater-disposal infrastructure capacity.

Cleaner fracking

New water treatment firms are developing chemical treatments and evaporators to remove contaminants from fracking wastewater, which can then be reused. The cost of disposal is spurring oil and gas companies to adopt these technologies, limiting the amount of contaminated water that reaches people, plants, and animals.

The ecology of natural gas

Researchers study natural gas impacts on drinking water, finding high methane concentrations near fracking sites. Gas leaks also cause soil changes, affecting urban ecosystems. The session discusses policy strategies to encourage cleaner natural gas distribution and reducing greenhouse gas emissions.
