Hi Scott, still believing that chemical treatment is the only solution? And normally NO PROBLEM? See this list as only a fragment of the number of cases where legionella caused deadly diseases.

You just invent an endless spiral - of continuous chemical usage. This is named perfect management? Just focus on one effect and ignore the impact of the chemicals to the environment? The continuous costs to supply these chemicals and the costs to neutralize thsi chemicals in waste water treatment? What is so difficult to at least seeking for other solutions? We can proof in various applications the effectiveness of non chemical treatments for years. Interested?  Then contact me: gerhard0261@gmail.com Best Regards, Gerhard Mangold
