Interesting they can tell all of that without a doctor ever having actually seen a single person. The study was based on self administered questionnaire ( http://ehp.niehs.nih.gov/wp-content/uploads/advpub/2016/8/EHP281.acco.pdf ). They admit there was bias, saying "...survey participants had poorer health (measured by the Charlson comorbidity index) than non-responders." And the lead researcher works with the Post Carbon Institute ( http://www.postcarbon.org/ ), one of their stated goals being "Busting the Shale Hype". All in all not exactly unbiased research. And let us not forget, correlation is not causation.
