Apart from the
contamination from nutrients already described, consideration has to be
given entry of pollutants into lakes and drinking water reservoirs (Graphic
example). All cases of contamination by pollutants must be prevented
whilst giving primary consideration to the aspect of drinking water usage.
Organic and inorganic pollutants behave in different ways in the ecosystem
of the lake. Compounds that are difficult to break down accumulate in the
biomass and the sediment whereas materials with shorter half-lives (pesticides
for example) do not always have to established by chemical analytic methods
but rather via their effect (on organisms in the water for example).
