As discussed, the main sources of heavy metal pollution are anthropogenic sources, which are the major concern for contaminants in groundwater as well as surface water resources. To overcome these problems, government must take appropriate action to solve these issues. In this regard, government has taken a decision to prevent and overcome heavy metal pollution in water.

NEERI (National Environmental Engineering Research Institute) has addressed the technique to decontaminate the water from heavy metals as well as for waste management of the land sector. The kit is also receommended to check the quality of drinking water (Marg 2011).

For preventing Hg pollution, the major Hg pollution sources like medical devices and CFL (compact fluorescent light) bulbs should be replaced by non‐mercury containing products (Marg 2011). The industries should set up treatment technology for spontaneous remediation of the heavy metal‐based wastewater before discharging the wastewater into water bodies.

Domestic wastage like municipal and sewage waste should be prevented from discharging in water. It should be monitored and made a rule to stop the disposal of waste in water. To cure the drinking water, the metal‐based pesticides and insecticides should be bonded within the agricultural field. Government must give proper attention to organic farming. Phytoremediation is a best tool to control the heavy metal contamination. Other spontaneous chemical and physical treatments have been utilized to overcome heavy metal pollution in water (Marg 2011; Talabi and Kayode 2019).
