Abstract
Ground water is the most valuable and scarce resource, and it can contaminate or pollute easily, due to which, the freshwater quality becomes expensive and difficult to restore. Therefore, many scientific tools are developed by the Environmental Protection regulatory agencies to protect the water quality in theearth’s ground water segment. Water gets collected underneath the surface of Earth. Groundwater stems from melting snow, ice and from rain. It percolates into the ground, to fill the empty spaces in porous rocks, sediment, and soil. Springs, Aquifers, and wells remain the main supply source and the groundwater flow. The water flows perennially is subject to heavy stress, due to its constant use for recreation, industry, water supplies, agriculture, and hence, it can easily get contaminated. Natural groundwater sources are contaminated because of mining like anthropogenic activities and also due to open dumping of domestic and industrial wastes leading to deprive groundwater quality. The pollution prevention and manipulation of groundwater is provided prior to evade expensive remediation because groundwater pollution is complex, invisible, and generates a long-lasting impact. This review paper assesses the groundwater pollution risks due to several pollutants.
