Solid residue in pure water?

    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!
