Michigan's Women's Huron Valley Correctional Facility, the state's only women's prison, is plagued by a toxic environment that endangers the health and safety of its inmates. A recent internal assessment has exposed widespread infrastructure failures, including aging HVAC systems, moisture intrusion, and poor ventilation, which create ideal conditions for mold growth.
The report highlights dozens of unresolved issues across various areas of the facility, many linked to humidity control, airflow, and water management. The prison's air-handling systems are outdated, difficult to regulate, or no longer functioning as designed, making it challenging to maintain a healthy environment.
The assessment documents multiple sources of moisture entering or persisting within buildings, including compromised roof drains, leaking roofs, and deteriorated steam and condensate lines. Ceiling tiles in several areas are described as rusted, sagging, perforated, or falling apart, indicating prolonged exposure to moisture.
Experts warn that surface-level fixes, such as painting over walls or replacing isolated ceiling tiles, do not resolve mold problems when moisture sources, ventilation failures, and building envelope defects remain. The report calls for multimillion-dollar capital projects to correct the issues, including the replacement of steam and condensate lines, electrical panels, doors and windows, HVAC components, and water-damaged flooring.
The Department of Corrections has repeatedly downplayed concerns about environmental health conditions at Huron Valley, despite documented evidence. In July 2025, a federal judge found that the prison's mold problem may violate the Constitution, citing allegations of respiratory infections, coughing, wheezing, rashes, dizziness, and fatigue.
The facility's management has been criticized for its handling of the situation, with many issues known internally before MDOC officials downplayed them. The prison's excessive moisture and lack of proper ventilation have created a breeding ground for mold, putting the health and safety of its inmates at risk.
