How long has water pollution been a problem?

Answer 1

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.

Answer 2

There are more than 1,200 places in England and Wales where groundwater is known to have been or is very likely to have been polluted by chemicals trickling down from the surface, according to the first nationwide survey of the problem by the Government's Environment Agency. Pollution from these "point sources" has contaminated the water in 114 boreholes used for the public supply and 137 private boreholes, and many of them have had to be closed because of the severity of the pollution.


The contaminated liquid emerging from landfill sites where garbage has been dumped for years is the cause of most of the known cases of groundwater pollution, but the agency identifies pollution from industrial sources as posing the greatest long term threat. Typical sources might be an old gas works, a petrol filling station or a dry cleaning plant. The agency admits there are big gaps in its knowledge of the problem, and the report is only a first stab.
