I am trying to find data on how much chlorine is too much or unhealthy. That is, at what point do the harmful effects of chlorine out weigh the benefits of the chlorine's ability to disinfect? I am a regulator for a local health department, and as such I do not have a single pool that I care for (though I see about 180 pools each year). That said, I am aware that other chemicals may make a difference so please assume the following:
Total Alkalinity- 130
I would like numbers (if they change) for CYA at 0,30,50,and 80ppm.
Anecdotal data is nice, but if you can post links to research, that would be great as I may need it to show the State Health department. Thank you all for your help, and I am sorry if this is posted in the wrong forum.
