More than 900 peer-reviewed publications assessing the effects of shale gas development now exist, with more than 230 published so far in 2016. Of the peer-reviewed publications on the health effects of fracking, 86 percent found risks or adverse health outcomes. Maryland’s Institute for Applied Environmental Health (MIAEH) also concluded that risks to public health and the environment are “high” or “moderately high” in 7 of 8 areas studied. More than half of the peer-review publications have been released since MIAEH completed its study in the summer of 2014.
