A Hudson Valley school will be closed for over a month after mold was found.

On Friday, classes were canceled for students at Elm Drive Elementary in Millbrook after visible mold was found.

An industrial hygienist performed air quality and swab tests throughout the school and the results came back positive for mold, officials say.

A mold remediation started on Saturday and will take around six weeks to complete, according to Millbrook Superintendent Phil D'Angelo.

Classes were again canceled for Elm Drive Elementary students on Monday. Students are scheduled to return to class on Tuesday and will be taught in the Millbrook Middle School.

"We will cluster 8 classrooms to keep Kindergarten, First Grade and Second Grade students together and separate from the Middle School students," D'Angelo wrote on the school's website. "Students and staff will not return to Elm Drive until the mold remediation is completed and I receive complete assurance that it is safe to do so."
