Groundwater pollution sources and restoration techniques

Groundwater is the water that is said to have gathered in the basement of saturated aqueous layers.One of the main sources of water supply in all countries of the world is considered and its use inagricultural irrigation and municipal and industrial uses is growing. Excessive use of groundwater andcontaminants entering the municipal solid waste from industrial sources, petroleum hydrocarbons,Pollution from heavy metals such as arsenic, radioactive waste and nitrates has caused many problemsfor these sources. So there are many ways to restore contaminated groundwater among the ways thatwe can deal with the leachate to groundwater, using iron nanoparticles for groundwater treatment, biocleanup of groundwater contaminated with petroleum hydrocarbons, including simulation methods tosimulate pumping methods - filtration and aeration of contaminated groundwater in place recoverynoted. The study concludes that nanotechnology methods in addition to a good performance that canbe the cost of drinking water from groundwater sources also minimized. And the best place for wastedisposal to prevent the infiltration of leachate into groundwater in arid and semi-arid areas is located.
