Question
Assume that a deep groundwater aquifer and a lake have been polluted to the same degree. In each the source of the pollution no longer exists, and so no new pollution is entering the system. Assuming only natural processes that move material in and out, and assuming the pollutant has the same residence time as the water in the system, which will "clean" itself up first? Why? Why do you think shallow groundwater has such a higher flux (~50x) than deep groundwater, when the deep groundwater volume is bigger?Explanation / Answer
(2) Ground water is the water that present under the earth surface.Lakes are above the earth with small amount of water like small basins.Now a days both the groundwater and lakes are getting polluted at a high rate.
Lakes may clean up first.Because ground water is having hundred times more than lakes.Using appropriate filters we can clean ground water also.But ,Lakes are small basins they can be cleaned easily .
(3) Compared to ground water shallow ground water is having higher flux because in shallow ground water five solutes were monitered daily at the catchement outlet and roughly every four months in the shallow ground water.Nitrate and chloride patterns are typical of an intensive agriculture catchement hydrologically controlled by shallow ground water.
