More than 100 Brighton homes will be tested for the cancer-causing chemical trichloroethylene (TCE), according to state officials.
The toxic chemical was found in the air of five homes in the neighborhood directly north of Brighton High School, and officials say more could be affected.
Rebecca Taylor from MDEQ says that the department detected no air issues at Brighton High School or Creative Kids Daycare.
According to the CDC, "it is used mainly as a solvent to remove grease from metal parts, but it is also an ingredient in adhesives, paint removers, typewriter correction fluids, and spot removers."
The contamination originated from manufacturing chemicals seeping into groundwater.
The source of the first plume, the defunct metal finishing manufacturing company Detroit Gaskets, polluted soil and groundwater with the chemical from the late 1940s to the early 1980s.
The source of the second plume is Haigh Manufacturing, which released the chemical into the ground in the 1960s and 70s.
Officials have been monitoring the plumes as a water issue since the early 1990s, when it was first detected.
But last year was the first time any air tests had been conducted related to the plumes.
Other serious health problems are also a concern, and the chemical can harm unborn babies.
