According to a recent study conducted by Dr. Janet Stout, a research professor at the University of Pittsburgh and a recognized expert on Legionnaires’ disease, cooling towers for hospitals and hotels, among other commercial buildings, do not effectively control growth of the Legionella bacterium by means of “green,” nonchemical devices alone.  Water temperature, growth of biofilm, and stagnant water in cooling towers, provide ideal conditions for bacteria, including Legionella, and forty to sixty percent of cooling towers tested for Legionella were found to contain the bacterium.  Dr. Stout recommends that building owners and engineers should closely monitor towers that rely on nonchemical means of microbial control, and if necessary, to add chemical means of control as well.
