There are more than five million wells fitted with hand pumps. People depend on tube wells for their drinking water requirements. Presence of arsenic in groundwater in excess of the permissible limit of 10 ppb (as per WHO) has been reported from West Bengal (India) and Bangladesh in significant percentage of wells.
More than 25 million people in India and Bangladesh are at health risk due to consumption of high arsenic in drinking water. Arsenic in water is invisible and has no taste or smell. Health effects from drinking arsenic contaminated water are delayed, starting with skin cancer. The accumulative nature of arsenic poisoning further results in various other forms of cancer.
Accurate and Periodic monitoring of arsenic levels in such a large number of groundwater sources using the present field test kits is proving difficult as they are not very sensitive and do not give consistent results.Testing of over five million wells, using atomic absorption spectrophotometer or UV -
spectrophotometer is not feasible due
to the wide spread of water sources, poor laboratory infrastructure at
the district level, logistics problems, resource crunch and high laboratory
testing costs. Therefore, Chem-In Corporation is now introducing a reliable,
sensitive and user friendly field kit which can measure Arsenic levels
in drinking water quantitatively.
