School is out for the summer. Thousands of schools across the country are locked up for a solid three months until faculty and students return for a new year in the fall. Many of these buildings sit dormant, with no HVAC system running. If the system is operating, it runs at a set temperature. In these situations, it is possible for mold and bacteria to form on books, in the carpet, and on the drapes.
While the seriousness of mold problems continues to be debated, there is no question that airborne pathogens and other forms of bacteria have created enormous problems for many schools. Some students come down with illnesses or rashes that cause buildings to shut down until solutions are put in place.
