A new study has found heightened concentrations of some common substances in drinking water near sites where hydraulic fracturing has taken place. The substances are not at dangerous levels and their sources are unclear, but the researchers say the findings suggest underground disturbances that could be harbingers of eventual water-quality problems. The study may be the first of its kind to spot such broad trends.

People living in areas of Pennsylvania where hydraulic fracturing is booming are suffering increasing rates of hospitalization, a new study says. The study is one of a small but growing number suggesting that the practice could be affecting human health. It appears this week in the scientific journal PLOS ONE.
September 04, 2014Ten years ago, hydraulic fracturing barely existed. Today 45,000 fracked wells produce natural gas, providing energy for millions of homes and businesses, and nearly a quarter of the nation’s electricity. But scientists are far behind in understanding how this boom affects people near wells. Geochemists Beizhan Yan and James Ross of Columbia University’s Lamont-Doherty Earth Observatory are trying to fill in this gap in rural northeastern Pennsylvania, where thousands of fracking operations have taken over formerly quiet hilltops, farms and back roads.

Earthquakes that have shaken an area just outside Youngstown, Ohio in the last nine months—including a substantial one on New Year’s Eve—are likely linked to a disposal well for injecting wastewater used in the hydraulic fracturing process, say seismologists at Columbia University’s Lamont-Doherty Earth Observatory who were called in to study the quakes.
