In the Spotlight

On Friday September 12, 2014, MdEHN, Chesapeake PSR, and ANHE co-hosted a symposium of experts to assess the findings of the study, Potential Public Health Impacts of Natural Gas Development and Production in the Marcellus Shale in Western Maryland.  There was general consensus that science is emerging that suggests health issues associated with various aspects of gas and oil well development need to be better understood, and that as a consequence, Maryland should not proceed with hydrofracturing at this time.
