Summary report of the 1982-84 studies on the incidence of Legionella in (A) Canadian environmental waters and (B) water distribution systems within public and private buildings / B.J. Dutka ... [et al.].: En13-5/85-89E-PDF
"This report summarizes a three-year study on the distribution patterns and densities of Legionella organisms in Canadian fresh waters and in water distribution systems within private and public buildings across Canada. The findings of this study lead us to believe that Legionella organisms are endemic to our freshwaters at very low levels and many potable water systems, where concentrations vary greatly. The report suggests that the contamination of potable water supplies by Legionella organims probably occurs through the occasional passage of Legionella organisms through the water treatment plant and then settles in a supportive less stressful and probably less competitive environment within potable water and cooling tower systems. Then when conditions are favourable for their proliferation, massive population increases and aerial contamination occurs. From current experience, coloniation of a water system with Legionella does not imply a health hasard, but the converse is true: where an outbreak occurs, colonization with the organism is likely to have occurred"--Abstract.
