A hospital was experiencing an increased occurrence of infections in one of their intensive care units. EMSL was hired to determine the cause of the problem. Initial Air Quality analysis revealed an unusually high concentration of airborne mold spores. Additional testing narrowed the problem to an air conditioning unit that was collecting the water condensed by the cooling coils producing a natural incubator for mold growth. The problem was compounded by the fact that the contaminated water was next to the fresh air intake for that wing of the hospital.
