I thought most water was now treated with chloramine and not chlorine? Though checking now all I can find are pages saying these are both common methods and nothing about which is more common.
(I don’t know if this is better or worse in your analysis, but you may be analyzing an obsolete treatment.)
Chloramine is used less than chlorine for drinking water disinfection, but is still used a lot these days, maybe for some weird regulatory reasons involving limits on reaction products from chlorine. I didn’t write about that mostly because it’s bad in more obvious ways (like formation of hydrazine groups), and isn’t used where I’ve lived, and thus it’s less interesting to me. But maybe I should’ve included it in this post?
MWRA uses ozone and ultaviolet light (UV) to kill any harmful bacteria at the CWTP in Marlborough. … To protect the water as it travels through the miles of pipe to get to your house, MWRA uses a mild disinfectant called mono-chloramine

Thanks! I was probably overgeneralizing from my local treatment plant:
