Public Trust in Pennsylvania Regulators Erodes Further Over Flawed Fracking Study

Raw data showing high concentrations of certain polllutants at gas operations and health risks of 25 chemicals were left out of the state's studies. The news was first reported Monday by the Pittsburgh Post-Gazette. The paper cited court documents that show how air quality studies conducted by the Department of Environmental Protection in 2010 and 2011 failed to analyze the health risks of 25 chemicals. The studies also didn't report some instances where high pollutant levels were detected.

The evidence came from statements of two DEP scientists who were deposed in a lawsuit.
