Many researcher have been studied that laterite is a good arsenic adsorbent (Maiti et al. 2007 of Separation Purification Technology, Maiti et al. 2008 of Industrial and engineering chemistry Research, Maji et al. 2007 of JHM etc. Thus laterite soil zones of the India and other countries are not effected by arsenic contaminated water due to its high affinity to adsorb arsenic species.

Yes, arsenic is a naturally occurring element found in rocks, soil, and water. In regions where there are high levels of arsenic in the geological formations, it can leach into well water, leading to potential contamination. Testing well water for arsenic levels is recommended, especially in areas known for arsenic presence.
Seltzer water hasn't arsenic.
The most likely reason for arsenic poisoning today is from ground water that naturally contains high concentrations of arsenic. Chronic exposure to arsenic is related to vitamin A deficiency which is related to heart disease and night blindness.
Arsenic contamination of water can be minimized if not totally prevented by banning boring of deep tube wells. With the ground water level receding alarmingly due to hapazard boring of deep tube wells for irrigation, for meeting the needs of urbanites, arsenic contamination is bound to occur. It can be minimized by encouraging harvesting of rain water by digging more ponds,canals in the rural area. In the urban area, supply of river water duly purified,will help conserve under ground water.
There are many natural contaminants out there. Here in Ohio we have issues with naturally occurring arsenic in ground water. The water may be fine, or it may not.
Arsenic is denser than water, so it will sink in pure water.
The number one would be China due to primarily industrialization and no regulations and the second place would be India, because geographically India has a lot more arsenic towards the surface so they have a high level of arsenic in a lot of the water which causes mental development problems to the people that are drinking it.
ANY arsenic in water is bad! :O
To remove arsenic from water, use a certified water filter that is specifically designed to remove arsenic. For soil or solid waste contaminated with arsenic, consult with environmental remediation experts for proper disposal methods. Avoid exposure to arsenic by limiting consumption of arsenic-contaminated food and water sources.
The rate of percolation in laterite soil can vary depending on factors such as soil composition, structure, moisture content, and porosity. Generally, laterite soils have a moderate to high rate of percolation due to their porous nature and ability to drain water quickly.
Usually from naturally occurring deposits of arsenic ore in the aquifer.
Arsenic can be removed from water in a few different ways. There are special filter media developed just for arsenic removal like the GEH-102 or similar. In domestic drinking water treatment, a reverse osmosis system can remove a large quantity of arsenic from water. Greensand filters can also remove a significant amount of arsenic, but is is dependent on the inlet iron content.
