Yes, many treatment facilities use chloramines which is a combination of chlorine/ammonia.
In my part of the country they will increase these level's in the spring and fall for a couple weeks to what they call,, flush the lines. they often have a very small notice published in the paper before they do this but it is often buried on the back pages and often goes unnoticed.
Might be worth investigating.
When they do this in my neck of the woods,i simply double the dose of PRIME I use during water changes and try to keep the changes smaller rather than performing large water changes during this time.
Do hope something helps.
