Question raised in Rajya Sabha on Chemical Contamination in Drinking Water, 06/02/2017. As reported by the States into the Integrated Management Information System (IMIS) of the Ministry as on 3 Feb 2017, the names of 100 districts belong to 13 States where high incidence of drinking water contamination found is given in Annexure.

Question raised in Rajya Sabha on Arsenic contamination in drinking water, 06/02/2017. As regards rural areas of the country, as reported by the States into the Integrated Management Information System (IMIS) of the Ministry as on 02 Feb, 2017, the areas of 66 districts of 8 states are in the grip of Arsenic Contamination. Details are attached as Annexure-1.

Metabolism of inorganic arsenic (iAs) is subject to inter-individual variability, which is explained partly by genetic determinants. Researchers investigated the association of genetic variants with arsenic species and principal components of arsenic species in the Strong Heart Family Study (SHFS).

Question raised in Lok Sabha on Community Drinking Water Purification Plants, 24/11/2016. With the recommendation of NITI Aayog, Government of India had provided funds to the tune of Rs 800 crore for installation of community drinking water purification plants in arsenic and fluoride affected habitations so that 8 to 10 litres per capita per day of safe water for drinking and cooking purposes is made available to the affected population as a short term measure.

About 76 percent of rural habitations in India have achieved a fully covered (FC) status, under the National Rural Drinking Water Program, with 40 liters per capita daily (lpcd), but this coverage is primarily through hand-pumps and does not necessarily translate into sustainable and good quality service delivery.

Inorganic soil arsenic (As) in three soils was fractionated adopting phosphorus fractionation schemes. Among these fractions, iron-bound arsenic (Fe-As) was found highest, followed by aluminium-bound arsenic (Al-As). The freely exchangeable arsenic was relatively small compared to the arsenic held by internal surfaces of soil aggregates. The arsenic fractions exhibited positive correlation with phosphorus content presumably due to the fact that high P in soil releases more arsenic from soil adsorption sites owing to the competition for the same adsorption sites.

Arsenicals (roxarsone and nitarsone) used in poultry production likely increase inorganic arsenic (iAs), monomethylarsonic acid (MMA), dimethylarsinic acid (DMA), and roxarsone or nitarsone concentrations in poultry meat. The association between poultry intake and exposure to these arsenic species, as reflected in elevated urinary arsenic concentrations, however, is unknown.

Many of the world’s megacities depend on groundwater from geologically complex aquifers that are over-exploited and threatened by contamination. Here, using the example of Dhaka, Bangladesh, we illustrate how interactions between aquifer heterogeneity and groundwater exploitation jeopardize groundwater resources regionally. Groundwater pumping in Dhaka has caused large-scale drawdown that extends into outlying areas where arsenic-contaminated shallow groundwater is pervasive and has potential to migrate downward.
