Eutrophication is a problem which became widely recognised by the
scientific community in the 1940s and 1950s. It raised public
concern, resulting in increased research effort and expenditure on
management techniques through the 1960s and 1970s, recognised as a
distinct problem of water pollution, though linked with the more
gross effects of organic pollution. In the 1980s it became less
fashionable - replaced in the public's eye and the politician's
purse by newer problems such as acid rain. It remains however, one
of the biggest and most widespread problems of fresh waters,
particularly of lakes and an increasing problem for estuaries and
coastal waters. It is one with which almost all water scientists
and engineers in urbanised areas of the world have to cope.
Technical methods for the reversal of eutrophication, such as
nutrient removal, have been developed and applied successfully in
some instances. They are not widespread however, and where they are
feasible, they are often expensive and may be politically difficult
to implement. In the last decade, attention has focussed upon less
expensive lake manipula tion techniques, such as destratification
and biomanipulation, which aim to minimise rather than elimininate
the detrimental effects of eutrophication. These are becoming more
widely applied. Prediction of the potential problems in lakes and
catchments which have not yet suffered the full effects of
eutrophication is now accurate enough to be of direct benefit to
river basin management."
