This depends on what you consider to be 'unclean'. Visibly unclean water would normally have been caused by mud/algae and thus be brown/red/green. The water could however have been polluted by something else, possibly a metal ore or salt, which could give rise to another colour. You could also consider bacteria to make water unclean, in which case it would often have no unusual colouring at all.
