Flint River Mystery Substance Raises Concerns

Genesee County in Michigan has issued an advisory for people to stay away from the Flint River after an unknown substance was illegally dumped into it. The City of Flint is investigating the incident but has yet to determine what the substance is or how it got there. The contamination has raised concerns about the river's pollution levels, which have been a long-standing issue due to industrial pollution. The city has faced criticism for waiting a week before investigating local sewer pipes to identify the source of the contaminant. The substance is believed to be a petroleum product, and tests are being conducted to confirm its identity.
