The world of environmental engineering science is moving from one paradigmatic challenge towards another. The paradigm of global water shortage is moving from one visionary and drastic challenges over another. Man's vision, civilization's prowess and the target of the provision of clean drinking water has urged human civilization to target new and innovative technologies. Arsenic and heavy metal groundwater contamination has evolved into a true emancipation of science and technology. Arsenic water pollution is the largest human disaster in this century. Environmental restrictions, environmental regulations and the urge of successful scientific endeavour are the need of the hour. Tools and environmental engineering innovations are gearing up for alleviating global water shortage. Human scientific research pursuit and the vision to excel has geared environmental engineering science to a new degree of awareness. The vision for the tomorrow is to gear towards a new dawn of environmental engineering techniques to alleviate this monstrous crisis. The incidence of this crisis is of monstrous proportion in South Asia and high concentrations of arsenic has emerged as a public health problem. The situation in the state of West Bengal, India and Bangladesh is grave. The contamination is due to both natural and anthropogenic sources. Concrete finding shows the vulnerability of the crisis. The study with deep comprehension focuses on the future perspectives of the world's largest environmental crisis. The author delineates with cogent insight, the state of environment, and the paper presents an overview of the current scenario of arsenic contamination in across the globe with special emphasis on South Asia. Heavy metal groundwater contamination is a bane to human civilization and human endeavour. The author brings forward along with the present situation in severely affected countries in Asia such as India and Bangladesh. Along with these countries, recent instances from Pakistan, Myanmar, Afghanistan, Cambodia etc. are presented. Challenges, barriers and catastrophes have urged the civil society to gear up for drastic and far-reaching challenges. Concrete findings suggest that the source of arsenic is geogenic. Arsenic is found in alluvial sediment of the Ganges Delta in India. This has led to much alarm and grave concern. Social isolation of the arsenic affected human beings, the society's unmitigated concern and the future of disastrous challenges has urged the scientific community to surge and gear forward in innovations. The author with incisive insight delineates the remediation technologies, the visionary future of scientific research pursuit in groundwater remediation and the future of advancement of science.

Abstract


The world of environmental engineering science is moving from one paradigmatic challenge towards another. The paradigm of global water shortage is moving from one visionary and drastic challenges over another. Man's vision, civilization's prowess and the target of the provision of clean drinking water has urged human civilization to target new and innovative technologies. Arsenic and heavy metal groundwater contamination has evolved into a true emancipation of science and technology. Arsenic water pollution is the largest human disaster in this century. Environmental restrictions, environmental regulations and the urge of successful scientific endeavour are the need of the hour. Tools and environmental engineering innovations are gearing up for alleviating global water shortage. Human scientific research pursuit and the vision to excel has geared environmental engineering science to a new degree of awareness. The vision for the tomorrow is to gear towards a new dawn of environmental engineering techniques to alleviate this monstrous crisis. The incidence of this crisis is of monstrous proportion in South Asia and high concentrations of arsenic has emerged as a public health problem. The situation in the state of West Bengal, India and Bangladesh is grave. The contamination is due to both natural and anthropogenic sources. Concrete finding shows the vulnerability of the crisis. The study with deep comprehension focuses on the future perspectives of the world's largest environmental crisis. The author delineates with cogent insight, the state of environment, and the paper presents an overview of the current scenario of arsenic contamination in across the globe with special emphasis on South Asia. Heavy metal groundwater contamination is a bane to human civilization and human endeavour. The author brings forward along with the present situation in severely affected countries in Asia such as India and Bangladesh. Along with these countries, recent instances from Pakistan, Myanmar, Afghanistan, Cambodia etc. are presented. Challenges, barriers and catastrophes have urged the civil society to gear up for drastic and far-reaching challenges. Concrete findings suggest that the source of arsenic is geogenic. Arsenic is found in alluvial sediment of the Ganges Delta in India. This has led to much alarm and grave concern. Social isolation of the arsenic affected human beings, the society's unmitigated concern and the future of disastrous challenges has urged the scientific community to surge and gear forward in innovations. The author with incisive insight delineates the remediation technologies, the visionary future of scientific research pursuit in groundwater remediation and the future of advancement of science.
