An alarming new study has identified 6600 chemical spills related to hydraulic fracturing in just four US states over a 10 year period. The finding shows that fracking is far messier than previously assumed, and that stricter safety measures need to be established and enforced.

It's generally believed that hydraulic fracturing is behind the recent spate of earthquakes in regions not usually associated with seismic activity, but the underlying processes are still poorly understood. New research from Canada strengthens the link between the two, showing how the controversial practice can produce persistent earthquakes even after fracking has ended.

Oklahoma was hit with an earthquake this week, its second 5.0+ quake this year. The increased number of earthquakes have been linked to the use of hydraulic fracturing, or fracking -- specifically the underground disposal wells where the run off from fracking is stored. The Oklahoma Corporation Commission has taken note of the relationship between the quakes and the wells and has ordered the shutdown of 35 disposal wells.

A 5.6 magnitude earthquake shook parts of the US Midwest earlier this morning, rattling homes from Nebraska to North Texas. The unusually strong quake will likely draw further scrutiny to the practice of disposing oil and gas field wastewater deep underground.
