I toured the Cedarburg plant years ago, as a student.
As CarpCharcin said, sodium hypochlorite is used as a disinfectant, this is dry chlorine, and what most plants in the US use these days. Any commercial dechlorinator should be effective when water changes are done.
The parameter that may influence your tanks the most, is
the water has a hardness of 21-24 grams, which converts to almost 400ppm, so it is mineral rich and very hard. Milwaukee is about 7-8 grains.
This means your choice of fish should be species that come from places like the rift lakes of Africa, or rivers and lakes in Central America. (Mbuna, African Peacocks, and convicts, JDs Live bearers, rainbow fish)are good examples of hard water species)
Fish like Amazonian species will be difficult to keep healthy long term, they often develop HLLE in hard water.
Wild angels, cardinal tetras, other Amazonian tetras, certain Uaru or chocolate cichlids, certain gouramis (chocolates) might be difficult to keep.
Many of these species prefer low pH (4-5)
Even common oscars will need more water changes in very hard water to remain healthy.
Aquarium strain may be more forgiving (but not long term)
As you can see in the report, nitrate is almost non-existent (0-1ppm) so no problem there.
Funny some more common parameters are left out of the report.
You may want to call them to ask/determine average pH and alkalinity.
Usually hard water has a high pH (8-9), and high alkalinity (100ppm), but not always.
Alkalinity is important because a high alkalinity helps buffer fish urine, and often mirrors pH, but if pH drops quickly your water change frequency may need to be adjusted up to prevent pH crash (acidification)
