At least one student has tested positive for lead poisoning after exposure at Golda Meir School Lower Campus. Lead hazards were widespread in the building, found on the ground in the boy's bathroom, cafeteria, a hallway, the teacher's lounge, kitchen areas and multiple rooms. Three other students at Trowbridge Street School of Great Lakes Studies, Maryland Avenue Montessori and Albert E. Kagel Dual Language School may have been lead-poisoned due to lead hazards from chipping lead-based paint and lead dust. Trowbridge Street School of Great Lakes Studies became the first MPS building to close due to its high lead levels, followed by Starms Early Childhood Center, Fernwood Montessori, and Lafollette School.
