Detroit stopped using CHLORINE in lieu of CHLORAMINE well over 10 years ago.Detroit DOES NOT use chlorine.Chloramine Does not disipate or evaporate, nor can it be boiled out, you must have a chloramine filter.
Detroit does NOT use chloramines and still uses chlorine as its disinfectant. Also chloramine as

states can easily be removed with a good carbon block.

The city of Detroit (and surrounding areas..e.g., Hamtramck) get their water from 5 drinking water treatment plants that are owned and operated by Detroit Water and Sewerage Department. One of these plants is located near Hamtramck but not owned nor operated by Hamtramck. For more info...here is the water report for Hamtramck. And here is the Report for DWSD

Actually, hamtramck purchases its water from Detroit, its public knowledge. Check hamtramcks water reports. What they do with it after they get it I wouldnt know.

Before you say misimformation please read all posts. I did say a good filter removes it and detroit hasnt used chlorine in 10 years. Look it up.
No. The carbon breaks the bond between the chlorine and the ammonia and removes the chlorine leaving the ammonia to be removed by the RO membrane which is only partially effective at all forms of ammonia(nitrites, nitrates etc.) and polished off by the DI resin.
Not sure about some of the recent posts here but chloramines are comprised of chlorine and ammonia. Any good quality 0.5, 0.6 or 1.0 micron carbon block such as the popular Matrikx +1 series is more than capable of removing the chlorine portion of the chloramines and a good mixed bed DI with proper contact time removes the ammonia. Carbons DO NOT remove the ammonia and the ammonia is what we are most concerned about here.
When I say proper contact time on the DI that means a full size, 10" vertical DI filter, packed properly and with bottom up flow so all resin and water come into contact with each other. Its no big deal and done every day.

You can disagree all you want about the chloramine use in DWSD, but you would be wrong. I work in the state agency that oversees drinking water quality in Michigan. I know we have a good handle on what each treatment plant is doing in this state.

Ok. That does make sense. I still believe detroit uses chloramine not chlorine, please prove wrong.
lol...I could ask the same from you.
Take a look at the water quality report I linked above for DWSD. Under Disinfectants and Disinfection By-Products, both list chlorine. By contrast, Lansing Board of Water and Light, one of the only four systems in Michigan to use chloramine, lists chloramine under their Disinfectants and Disinfection By-Products section (you'll have to click on "Tables" to see it).

Im here to learn. Ive seen a report that said chloramine so forgive me for not taking your word, I like facts. Please if u can pointe in the right direction.
How many different sources does the Detroit area have? I know in the Phoenix Metro area there are literally a dozen or more major surface water treatment plants fed by three major sources so each has a different blend of water, different treatment method and several different disinfection methods. Some use free chlorine, some chloramines, others chlorine dioxide which is very popular here and yet others Ozone or UV followed by a small dose of chlorine. Some use gaseous chlorine, some liquid sodium chloride, some erosion feeders using tablets or calcium chloride and some have chlorine generators which use salt and electricity to create a weak chlorine solution.
The thing is you never know what is being used or what the real time water quality is, it even changes in the distribution system after leaving the plants. Would I drink it? Absolutely with no reservations. Would I put it in my reef tank? Absolutely not! I want stability and a known product and the only way to get that is having your own personal RO/DI system.
