The New York Times obtained documents from the Environmental Protection Agency, state regulators and drillers that show the environmental and health dangers posed by hydraulic fracturing are greater than previously understood.
For instance, wastewater from the drilling process is sometimes hauled to sewage plants that are not capable of properly treating the water. As a result, it is discharged into rivers that supply drinking water, still containing dangerously high levels of radioactive waste.
Other documents reference unreleased reports prepared for the EPA and show the concern of EPA scientists over the safety of Pennsylvania drinking water, as a result of "fracking" practices.
The Times also said it found never-reported studies by the E.P.A. and a confidential study by the drilling industry that all concluded that radioactivity in drilling waste cannot be fully diluted in rivers and other waterways.
