Last month, the Colorado Department of Public Health and the Environment announced it would investigate a spike in rare fetal anomalies reported in Garfield County, the second most heavily-drilled and fracked county in the state.
The newly released report, which the department quietly put on its website without public announcement, does little to address fears about the safety of drilling and fracking in Colorado's communities.
The report says that overall, the department found no single predominant risk factor common among the majority of women studied.
The agency studied about a dozen risk factors, most of which focused on the mothers' personal characteristics and behavior, such as ethnicity; alcohol, tobacco and drug use; use of medications, vitamins and supplements; and family history.
But the report has glaring gaps in what the state examined, and what it didn't.
