Arsenic in groundwater
Dr. Shikha VishwakarmaArsenic is widely distributed throughout the earthâ€™s crust, it is introduced into the water through the dissolution of minerals and ores.Industrial waste also contributes to arsenic pollution when run-off from orchards where arsenic is used mixes with the groundwater.The combustion of fossil fuels also pollutes the environment with arsenic through atmospheric deposition when water from rains brings the arsenic to the ground.
