"After more than five years and about 6,000 wells drilled in the Marcellus Shale boom, public-health experts say the need to collect information near fracking operations in Pennsylvania is urgent.

A health registry could show trends of illnesses, collect data and potentially answer the question of whether fracking is safe — a debate currently characterized by emotional arguments with little reliable information.

How will anyone in the state know the possible health impacts of hydraulic fracturing unless information is collected?

A health registry 'is a critical issue that needs to be addressed,' said Dr. Ralph Schmeltz, an endocrinologist and former president of the Pennsylvania Medical Society."
