Failed Pipe Insulation Blamed for Mold Contamination at Two Illinois Schools
Mold remediation at two schools in Mount Prospect, Illinois provides an excellent example of why finding mold is only part of solving a contamination problem. Investigators traced the underlying moisture to failed insulation on chilled-water lines, which allowed condensation to develop. The district’s response has included mold removal, replacement insulation, commercial dehumidification, deep cleaning and post-remediation indoor air quality testing. This story is particularly valuable for building owners and facility managers because it illustrates a fundamental principle of mold remediation: unless the moisture source is identified and corrected, removing visible mold alone does not solve the underlying problem.
