A county in southeastern Michigan wants to determine the effectiveness of sampling and studying sewage to see whether hot spots for the COVID-19 virus can be traced.
The pilot project was expected to start in June in Macomb County, just north and northeast of Detroit.
Samples will be collected twice each week from seven sites in Clinton Township. If successful, the pilot project can be expanded to other parts of the county, according to Macomb Public Works Commissioner Candice Miller.
