Dave Dempsey will discuss the topic of toxic chemicals present in our groundwater. Almost 50 years ago, Michigan suffered one of the worst human exposures to a toxic chemical in its history when PBB accidently entered the state’s food supply. In more recent years, our exposure to PBDEs and PFAs has raised the question of whether we have learned anything about the dangers persistent chemicals present to human health. Q&A will be hosted through Facebook live comments or using the Q&A feature on Zoom (link below). This event will be moderated by Anne Magoun.
