Mold was found at both William Paterson University and Montclair State University.
At least three dozen students were relocated from their dorm rooms at William Paterson University.
According to reports, seven of 10 residence halls were found to have mold.
The university told NorthJersey.com they are paying at least $2,500 per room to clean the mold.
Montclair State University says surface mold was found in a small number of rooms on campus.
Most of the locations have already been treated.
Students were offered the option to relocate.
