Scientists and experts in Kolkata dealing

exploring
the
possibility that Kolkata’s drinking water

more Arsenic than just before the tremors of

suggested by WHO is just 10 micrograms
per liter, water samples collected from some
areas in south Kolkata, such as Jadavpur and
Bikramgarh contained much higher doses of
Arsenic- some samples even contained 199
micrograms per liter. The possibilities are
