Error Found in Penn State Fracking & Water Well Study

oopsMDN recently highlighted a new study of several hundred water wells by Penn State researchers which found no evidence of chemical or methane contamination related to nearby Marcellus gas drilling (see this MDN story). The study did announce one oddity in the data: increased levels of bromide in seven wells. That oddity has now been explained—it was a lab error. Oops. Bottom line conclusion from the study?
