Arsenic Poisoning in West Bengal : Treatment Plant

FATE OF THREE CRORE RUPEE ARSENIC REMOVAL PLANTS IN MURSHIDABAD

...Previous

How effective these plants are in removing arsenic

Out of the 34 plants in Domkal that we have been able to collect samples from, according to Table-1, in 5 of them the arsenic level is very low (less than 3 microgram/litre), and in 9 the level is below that approved as tolerable by the Govt. of India (50 microgram/litre). Among the remaining 20, the plants have reduced arsenic from 13 contaminated tubewells to a level of below 3 microgram/litre. The removal is above the WHO-recommended level, and below the Govt. of India's level in 6 cases. The only non-functional plant (Table-1, serial no. 25) is in Garaimari village, at the Free Primary School. The plants are, therefore, suitable for arsenic removal, but are not functioning properly owing to associated problems.

How successful these plants are in removing iron

According to the Director and the Manager of Pal-Trockener, the first column of these plants is meant for iron removal. Table-2 shows the degree of success in iron removal. According to the WHO, iron content must not exceed 300 microgram/litre in drinking water.
