    I would like to add an advisory to Celenza and Shank's June 2019 paper: Jurisdictions may have permitting/registration/other requirements for cooling towers on account of Legionnaires' disease. The economic analysis should check if this is the case at the proposed location.

    Thankyou,

    As an even later comment, I would add that tower bacterial control is an imperative.  Back before chromates were banned, they served as a passivator and a disinfectant because of their toxicity.  Then some companies went to and may still be using antimony as a passivator, but I'm not sure how good it is as a disinfectant on bacterial life.
    The important point is that part of tower control should include some type of disinfectant to control bacterial growth.  The alternative is Legionella if you don't control your cooling tower.
