The US Environmental Protection Agency and WI Department of Natural Resources are co-leading the effort and working with other federal and state agencies and contractors to monitor water quality in response to the industrial fire in Superior. The Lake Superior Reserve and other science organizations in the Twin Ports are offering support. The scientific process is deliberative and, while we are collecting data in real time, we do not have immediate analysis. If you have time sensitive questions about water quality, please contact public agencies. If you have specific questions about the refinery fire contact Rachel Bassler, Public Information Officer with the EPA, bassler.rachel@epa.gov or (312) 886-7159.
