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.
