UPDATE (6/16/2022, 2:30 PM EST): The Colorado Department of Public Health and Envrionment (CDPHE) has issued a statement on the survey acknowleding the limitations of the authors’ findings:
“Surveys of this nature contribute to the scientific evidence by identifying potential public health concerns that may need further investigation, but there are limitations, as there is with all research. (As) the survey authors note, self-reported outcomes can make it difficult to assess the extent to which perceptions about oil and gas activity influence participation in the survey and responses to survey questions.” (emphasis added)
Researchers, including the University of Colorado School of Public Health’s Lisa McKenzie, whose past work has been criticized by the Colorado Department of Public Health and the Environment, presented the preliminary findings of a recent health survey conducted for the City and County of Broomfield at a town hall Thursday night to a virtually empty room.
And while the research team said the full data set for the $55,217 taxpayer-funded survey will be available to the public in coming weeks and acknowledged they have not yet had a manuscript peer-reviewed or published, CCOB’s Senior Environmental Epidemiologist Meagan Weisner also admitted:
“This study won’t tell us the cause of the symptoms, so we cannot prove causation that oil and gas emissions caused an increase in symptoms…We don’t really know the cause.”
That sentiment was further echoed by CCOB’s Department Director Andrew Valdez:
