The SAR Technology was developed by a consortium of European &
Indian scientists led by Dr Bhaskar Sen Gupta, OBE from Queen’s
University Belfast, UK & demonstrated at a location near Kolkata
during 2005-06 (www.qub.ac.uk/tipot). The technology was
subsequently replicated successfully inarsenic affected areas in
West Bengal through World Bank Development Marketplace 2006
programme. The technology involves a very simple and easily
adaptable process to remove arsenic and other heavy metals from
groundwater using controlled oxidation without production of
sludge & not using any chemicals at all. This technology can
transform the way arsenic is removed from groundwater in Ganges,
Brahmaputra and Mekong delta region in India, Bangladesh,
Cambodia, Nepal, Vietnam and Thailand. Also USA and Mexico are
the two areas where this technology can be useful. Further R&D
is being carried out by QUB-UK, NML-India & UM-Malaysia. The
Arsenic status in USA has been given in the map. Is there
