"ProPublica examined government environmental reports and private lawsuits and interviewed scores of residents, physicians and toxicologists in four states—Colorado, Texas, Wyoming and Pennsylvania—that are drilling hot spots. Our review showed that cases like Wallace-Babb's go back a decade in parts of Colorado and Wyoming, where drilling has taken place for years. They are just beginning to emerge in Pennsylvania, where the Marcellus Shale drilling boom began in earnest in 2008.
Concern about such health complaints is longstanding—Congress held hearings on them in 2007 at which Wallace-Babb testified. But the extent and cause of the problems remains unknown. Neither states nor the federal government have systematically tracked reports from people like Wallace-Babb, or comprehensively investigated how drilling affects human health.
"In some communities it has been a disaster," said Christopher Portier, director of the U.S. Agency for Toxic Substances and Disease Registry (ATSDR) and the National Center for Environmental Health. "We do not have enough information on hand to be able to draw good solid conclusions about whether this is a public health risk as a whole."
Exemptions from federal environmental rules won by the drilling companies have complicated efforts to gather pollution data and to understand the root of health complaints. Current law allows oil and gas companies not to report toxic emissions and hazardous waste released by all but their largest facilities, excluding hundreds of thousands of wells and small plants. Many of the chemicals used in fracking and drilling remain secret, hobbling investigators trying to determine the source of contamination. The gas industry itself has been less than enthusiastic about health studies. Drillers declined to cooperate with a long-term study of the health effects of gas drilling near Wallace-Babb's town this summer, prompting state officials to drop their plans and start over."
