ST. CLAIR SHORES (WWJ/AP) – Initial tests show stinky muck that collected in 2011 along the Lake St. Clair seawalls of some homes in St. Clair Shores is algae.

State environmental officials on Wednesday plan to unveil a DNA profile of the muck. The Michigan Department of Environmental Quality is holding a meeting at MacRay Harbor in Macomb County’s Harrison Township at 6 p.m.

State Rep. Tony Forlini told The Macomb Daily he thinks the DEQ’s findings “are really going to raise some eyebrows.”

Initial tests found that the material was made up of algae that may have been compounded by storm water runoff, municipal wastewater discharge and zebra mussels.

The muck was reported as a problem in 2011 after residents complained of a buildup on their seawalls that trapped dead fish and debris. Officials got in touch with the state about how to address the problem.
