Legionaire's outbreak and information

Two death's from Legionaire's disease are reportedly linked to a downtown Marriott Hotel in Chicago, Illinois.  Chicago Tribune reporter, Mitch Smith confirmed that the hotel has drained the pool, whirlpool and fountain.

Several non fatal legionella cases in Wisconsin were caused by exposure to a decorative fountain that was heated by lamps and a nearby fireplace.

Recommendations for decorative fountain maintenance as commissioned by the South Dakota department of health are listed on this pdf.  Below water lighting, plastic pipes and poor treatment of water contribute to problems with the decorative fountains.  Keeping the temperature below 65 degrees and maintaining at least 0.5 ppm of chlorine will reduce problems with legionella.
