So after some in-depth discussion, we figured out that we weren't really certain about some things in our models that explained how water changes from Lake Michigan to our tap.
1. We weren't certain on the building...is it the purification plant or the wastewater treatment plant that cleans Lake Michigan water? We were aware of this weird building near Navy Pier, and it's pretty much on the Lake.
2. We weren't certain on how stuff gets removed and added to the water. Is it just like the WWTF? Or are the processes more like what happens when water goes deep underground and becomes clean from going through earth materials?
3. We also weren't sure on how pipes may play a role in adding stuff to water.
So Mrs. Brinza found this great movie to watch to help gather evidence!

Before the Faucet, After the Flush
Provides an overview of how tap water is purified, pumped and delivered to Chicago area residents and business; how the waste water and sewage is transported, treated and returned to our rivers and streams for reuse.
And we revised our models to this!!!
