As fracking amongst Marcellus Shale in the northeastern part of the United States increases so does the concern over its process. Fracking is done utilizing a hydraulic fracturing process, which pumps a high-pressure mixture of water, chemicals and sand deep into the sedimentary formations to extract naturally occurring gas. The resultant

Excess Radioactivity and Metals Found in Pennsylvania Fracking Wastewater
written by Yale Environment 360
Researchers found high levels of radioactivity, metals, and salts in sediments and water downstream from a Pennsylvania facility that treats fracking wastewater. Radioactivity levels downstream of the treatment plant were about 200 times higher than in surrounding areas, and concentrations of some salts and metals were also higher than background levels,
A new study estimates that fluids used in the hydraulic fracturing of natural gas in the Marcellus Shale region can migrate into underground drinking water supplies far more quickly than experts have previously estimated.
The study, based on computer modeling and funded
