This powerpoint presentation begins by providing background information on Legionella pneumophila in water systems. A study was done on controlling Legionella byaltering typical water qualityparameters. Tested conditions are given, along with factors for two different base waters, and the experimental set-up. Results observed no effect for alkalinity,organic matter,potassium and nitrate,phosphate, ammonia, andiron. Conclusions showeda significant decrease in Legionellaresulted from:adding 2160 ppb Cu<sup>2+</sup>;raising the pH to 11; and, raising the temperature to 53ºC. Includes figures.
