DEQ's NOAA Sea Grant Fellow, Andrew Kirk, created a fantastic educational video for his advanced science communications course. This is a whiteboard animation video describing what polychlorinated biphenyls are, how they are used, why they are toxic to humans, and what we can do to avoid them. DEQ works to address PCB contamination in its watershed planning and remediation programs.
