Question
2. 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? 3. 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. if there are no other sources of pollution for deep aquifer and lake then, total budget of water quality can improve by several natural processes. Assuming that on the basis of contamination in water bodies, it must be classified into the criterion of using it on daily usages. Some natural and artificial technique to recharge these sources with monitored standard quality of water through infiltration, seepages, borehole inputs and ditches etc can be beneficial to replace the water content. With time elapsed, the quality of water can be improved with such practicing.
3. In some cases where shallow subsurface material is more of unconsolidated materials and thus having more yield porosity than the deep aquifer. The higher value of yield porosity contributes to the higher value of flux intake from the reservoir.
