Unregulated Fracking Poses Ongoing Threat To Environment

Up to 16% of hydraulically fractured oil and gas wells spill liquids every year, according to new research from US scientists.

They found that there had been 6,600 releases from these fracked wells over a ten-year period in four states.

The biggest problems were reported in oil-rich North Dakota where 67% of the spills were recorded.

The largest spill recorded involved 26,000 gallons of fluid with most related to storing and moving liquids.

The key to the United States' energy production over the last 15 years has been the use of hydraulic fracturing, the process of injecting fluids with chemical additives under pressure to crack underground rock and release the trapped resources.

However, environmental campaigners have long been troubled by the potential for this process to contaminate water supplies and the environment through leaks and spills.  Check out the BBC for more details.
