"As water enters the treatment plant, a chlorine solution is added to kill microorganisms and viruses that can cause disease."
What's a "chlorine solution"?
Water department workers not directly involved with the treatment process will tell you they use chlorine. When we had a mechanical water related problem in our residence a few years ago, I asked the fix-it guy in the truck about what the city used to treat the water, knowing already about the chloramine. He said "chlorine". I think the word "chlorine" is often used because it's simpler to say and explain compared to the complexities of chloramine.
Probably the best way to find out what is actually in the water is to contact one of the lab techs at a WTP and ask if they use chloramine or chlorine. That's what we did when we first got into keeping FW fish.
