Researchers progressing in fatberg study
A fatberg discovered in a Macomb County sewer had led to a more introspective look on the subject, courtesy of a pair of Wayne State University researchers. Barely more than a year ago, Macomb County Public Works Commissioner Candice Miller stood at a podium and discussed how a 100-foot long, 19-ton fatberg was discovered in a sewer 50 feet underground as part of the Lakeshore Interceptor along Interstate 94. A few months later, Wayne State University researchers acquired an $86,000 National Science Foundation grant that has allowed them to study how fats, oil and greases, or FOGs, lend themselves toward these environmental blobs. It also helps compile a model, aimed to predict future situations when fatbergs might arise — not just in Macomb County, but anywhere. “We’ve been working very closely with the Macomb County Department of Public Works to investigate the whole fatberg phenomena,” said Carol Miller, professor of civil and environmental engineering and director of Healthy Urban Waters at WSU. “Macomb County has been really helpful, and we have a wealth of information regarding system characters, and data regarding pressure flows of pipes before and after the fatberg.” Carol Miller works alongside Tracie Baker, assistant professor in WSU’s Institute of Environmental Health Sciences. Their research as part of the grant will continue for about another four months.
