Science Fair Project: Natural Water vs Bottled

[Experiment22]

Hello I'am a high school student doing a science fair project on the chemicals and heavy metals found in both natural water sources(lakes,rivers,streams) and bottled. I'am looking to see if anyone has information like a list of chemicals and heavy metals found in both sources. any reply is greatly appreciated.

If you gather a list yourself and ask if it seems complete, you're likely to get help here, but what you posted is that want us to do your research for you.
