They don't use chlorine?

  From the article: > the city’s water regulator uses liquid oxygen as part of its process for removing foul-smelling hydrogen sulfide from water pumped in from the Lower Floridan Aquifer.

    I live here and have a well, the aquifer water is pretty much rotten eggs.

  They use chlorine. The liquid oxygen is used to produce ozone, which, in addition to solving their taste and odor issues, is a potent disinfectant. However, ozone doesn't leave a detectable disinfectant residual in the water like chlorine does. Testing for that residual allows you to show that at any given tap in your distribution system, the water remains disinfected. By using ozone for primary disinfection, you can greatly reduce the amount of chlorine you add to the water before you send it out into the distribution system, so you end up with fewer undesirable disinfection byproducts. Orlando's problem seems to be that they don't have the capacity to adequately disinfect the water with chlorine alone.
