Asbestos Contamination in Puerto Rico's Schools and Public Housing

Between the 1940s and 1970s, Puerto Rico underwent massive construction of public infrastructure under the Commonwealth's modernization programs. Hundreds of schools, public housing projects, hospitals, and government buildings were built using asbestos-containing materials (ACMs) — including floor tiles, ceiling tiles, insulation, pipe wrapping, and roofing materials. Asbestos was widely used because of its fire-resistant and insulating properties, and its dangers were not yet fully understood or regulated.

By the 1980s, when the EPA began regulating asbestos in the United States under the Asbestos Hazard Emergency Response Act (AHERA, 1986), Puerto Rico's public buildings had already accumulated decades of deteriorating ACMs. AHERA required public schools to inspect for asbestos, develop management plans, and conduct abatement where necessary. However, implementation in Puerto Rico lagged behind the mainland due to limited funding, insufficient trained inspectors, and the colonial government's competing budget priorities.

The Puerto Rico Department of Education, which oversees approximately 1,100 public schools, has repeatedly acknowledged the presence of asbestos in hundreds of buildings. However, comprehensive abatement has been slow and underfunded. Periodic inspections have revealed damaged ACMs in classrooms, cafeterias, and gymnasiums, posing inhalation risks to students and staff. Teacher and parent organizations have filed complaints and organized protests demanding remediation.

Public housing complexes, many built under the federal public housing program, face similar problems. Deteriorating floor tiles, insulation, and pipe wrapping release asbestos fibers into units where families live. Maintenance workers who disturb ACMs without proper training and equipment face elevated exposure risks.

Hurricanes have dramatically worsened the asbestos problem. Hurricane María in 2017 damaged roofs, walls, and ceilings across the island, fragmenting asbestos-containing materials and dispersing fibers. Demolition and reconstruction work in the aftermath often failed to follow proper asbestos abatement protocols, particularly in the chaotic early months of recovery. The problem illustrates how colonial underfunding of infrastructure creates compounding environmental health hazards.
