Hydraulic fracturing (“fracking”) is a technology employed in the production of oil and gas from unconventional shale formations. Over the last decade, tens of thousands of fracking wells have been drilled worldwide. Fracking often takes place in relatively populated areas, thus posing an array of risks to public health such as water contamination and induced seismicity. In addition to inspecting and monitoring these risks, regulators now face the challenge of keeping the public well informed about their extent.
