Two more schools in the state have been closed because of mold problems.
Buena Regional School District announced Monday Dr. J.P. Cleary Elementary School and Collings Lakes Elementary School were closed.
According to authorities, air quality tests revealed mold in both schools.
Officials are working to remediate both schools. Dr. J.P. Cleary Elementary School is expected to be closed for about three weeks.
Collings Lakes Elementary School is expected to be closed for two weeks.
District officials are working with the Atlantic County Office of Education to determine "options for relocation."
More than a dozen schools across New Jersey had to delay the start of the new school year or section portions of their buildings because of mold.
