As long as there has been water there has been water pollution.
Natural water pollution occurs when salt water flows into fresh water, animals die in the water, river banks erode, or volcanic gases mix with water.
Man made water pollution has existed as long as there have been people. Early settlements used water for sewage disposal, poisoned streams to kill fish and drove cattle through streams. As our settlements and farms grew bigger and we got more numerous water pollution increased. In the middle ages fair sized cities still used streams as sewers, by the Industrial Revolution all sorts of toxic materials from mines and new industries were discharged along with sewage.
Today we take a bit better care f the water but are using so much of it that the supply that is left can be degraded easily.
