Is Solid Residue Present in Pure Water?

[KiraraChem]

Hi everyone!
If I have a sample that didn’t present conductivity and left a solid evaporation residue but its density is approximately 1 g/mL (1,08 g/mL), can I still say it is pure water?
I suppose pure water shouldn’t have any kind of solid residue.

Thanks!

And you are right.
