MINISTER OF STATE IN THE MINISTRY OF AGRICULTURE AND FARMERS WELFARE
(SHRI SUDARSHAN BHAGAT)
(a) & (b): Studies conducted by Bidhan Chandra Krishi Viswa Vidyalaya, Kalyani under ICAR funded projects during 2006-2012 revealed that there is considerable accumulation of arsenic in vegetables grown with arsenic contaminated groundwater. It has been found that edible parts of leafy and underground vegetables contain higher arsenic as compared to fruit bearing vegetables.As per 19th Report of Committee of Estimates (2016-17), Ministry of Water Resources, River Development and Ganga Rejuvenation, nearly 70.4 million population is affected with arsenic contamination and 2 to 3 lakhs of confirmed cases of arsenic illness have been identified.The arsenic contamination in groundwater, presently, spread over 96 districts in 12 States.
(c) The ICAR has recommended conjunctive use of fresh surface water and poor quality groundwater along with other agronomic measures such as application of vermi-compost, FYM, Green manure, and Zinc sulphate to minimize the adverse impact of irrigation with arsenic rich groundwater. Remedial measures undertaken in arsenic contaminated areas include sharing of groundwater quality data for creating awareness; exploratory drilling carried out for tapping contamination free aquifers in the contamination affected areas; and undertaking the National Aquifer Mapping Programme including construction of tube wells for tapping arsenic safe deeper aquifer.
(d) Yes, Madam. As per Central Ground Water Board (CGWB), Ministry of Water Resources, River Development and Ganga Rejuvenation, groundwater of Prakasam district, Andhra Pradesh contains fluoride above the permissible limit (1.5 µg L-1) but arsenic concentration is within the safe limit.
(e) Measure such as recharging the groundwater by rainwater harvesting for irrigation purpose need to be practiced to improve the groundwater quality in this area.The Government has formulated a National Water Quality Sub-Mission for focus funding to schemes meant for mitigating arsenic and fluoride contamination on cost sharing basis between centre and state. Under this mission, the goal is to provide safe drinking water to arsenic and fluoride affected habitations from sustainable water sources.
