Abstract
Pure water is very essential for all living organisms and it depends on the source because water quality effects on health of people. Analysis of heavy metals in potable water is necessary, must be under permissible limit as per WHO and BIS. These enter in water naturally through rock weathering, volcanic eruptions, wildfires, rain, dust deposition, and water interactions with rocks and soil (Gupta, et al., 2013 and Sheykhi and Moore, 2016). Industrial pollution, medicinal pollution, air pollution and water pollution etc. are also responsible for this type of pollution. Rajasthan is known for its arid climate and people face significant challenges related to freshwater availability. In a study, it is found that some water samples are highly contaminated with heavy metals like lead (Pb), selenium (Se), and mercury (Hg). By using statistical analysis, it is found, that the some heavy metals are from human activities and other from geological. This review is carried out to study heavy metals pollutants in drinking water and its effect on health and emphasizes the need for awareness and mitigation.
