Radioactivity from oil and gas wastewater persists in Pennsylvania stream sediments

Radioactivity from oil and gas wastewater persists in Pennsylvania stream sediments 01/26/2018 08:01 AM EST More than seven years after Pennsylvania officials requested that the disposal of radium-laden fracking wastewater into surface waters be restricted, a new Duke study finds that high levels of radioactivity persist in stream sediments at three disposal sites. Radioactivity at these sites is 650 times higher than at unaffected sites upstream. The contamination comes from conventional, or non-fracked, oil and gas wastewater.
