Over the last decades, groundwater has become one of the important sources of water for human and animals provided by nature. Unfortunately, the groundwater gets contaminated both knowingly and unknowingly by human carelessness. The natural sources explained in Section 4.2.1 are major causes of groundwater contamination. These natural sources are playing a part in contaminating the groundwater by heavy metal. The excavation of rock, which is a rich source of heavy metal, creates the heavy metal pollution in groundwater because the heavy metals are easily soluble in water, and can also be suspended in water. Additionally, anthropogenic sources are a big contributor to the heavy metal pollution in groundwater.
