Anthropogenic sources (caused by human activity) are the main source of heavy metal pollution. Industries and chemical companies directly discharge contaminated water without any pretreatment in groundwater and surface water sources. On the other side, agricultural irrigation is a huge reason for the degradation of drinking water quality owing to excess use of various types of harmful pesticides, fertilizers, and insecticides for crop production (Talabi and Kayode 2019). Other reasons for water pollution are discharge of sewage waste (wastewater, waste dump, and solid waste), exoneration of the by‐products and wastes produced by mining activities, dissociation of radioactive elements, over pumping, etc. The discharges of waste chemicals (inorganic and organic) by laboratories, experimental wastes which are directly thrown in water, are some types of anthropogenic sources which deteriorate the water quality. These anthropogenic activities are more toxic and harmful for humans as well as animals.
