Protecting Puerto Rico’s Indoor Environments After Flooding: Reducing Health Risks During Recovery

Flooding remains one of the most significant environmental challenges facing Puerto Rico, especially during hurricane season and periods of heavy rainfall. While communities often focus on visible structural damage after a flood event, hidden indoor environmental hazards can persist long after floodwaters have receded.

According to guidance from the U.S. Environmental Protection Agency (EPA), buildings affected by flooding may contain mold, bacteria, sewage, chemicals, and other contaminants that can negatively impact indoor air quality (IAQ) and pose potential health risks to occupants. Mold growth can begin within 24 to 48 hours when moisture remains trapped in building materials, making prompt cleanup and drying critical.

The EPA recommends several important steps for safe flood recovery, including protecting personal safety, removing damaged materials, thoroughly cleaning affected areas, and ensuring buildings are completely dried before reoccupancy. Individuals involved in cleanup efforts should use appropriate personal protective equipment (PPE), including N-95 respirators, gloves, eye protection, long sleeves, and waterproof boots.

In Puerto Rico, where tropical weather and high humidity can accelerate mold growth, special attention should be given to water-damaged materials. Non-porous surfaces can often be cleaned and restored, while porous materials such as carpeting, insulation, ceiling tiles, and certain furnishings may require removal and replacement if they cannot be adequately cleaned and dried.

“Flood events are a reality for many communities throughout Puerto Rico, and the environmental impacts can extend far beyond what is visible,” said Harry Peña, President of Zimmetry Environmental. “Environmental testing and industrial hygiene assessments can provide valuable information to help property owners make informed decisions during the recovery process.”

Zimmetry Environmental supports flood recovery efforts across Puerto Rico by providing environmental testing, industrial hygiene consulting, indoor air quality assessments, and remediation oversight services. These resources help facility managers, property owners, schools, healthcare facilities, and businesses identify potential environmental concerns and develop effective recovery strategies following flood events.

The company also recently sponsored an educational video that discusses ways to protect indoor air quality and health during flood cleanup activities. It can be seen at: https://youtu.be/hN49Ci4lS9o
