Answer given by the minister

THE MINISTER OF STATE IN THE MINISTRY OF WATER RESOURCES (SHRIMATI BIJOYA CHAKRAVARTY)

(a)&(b) The Central Ground Water Board (CGWB), under the Ministry of Water Resources monitors ground water quality throughout the country on regular basis. The studies carried out by the CGWB indicate that the ground water in major parts of the country is by and large potable. There are, however, areas which have poor quality of ground water mainly due to the contamination from industrial and domestic effluents, excessive use of fertilizers, mining wastes, saline water ingress and due to the nature of the ground water bearing rock formations. The names of States and locations where ground water has been found contaminated and reasons thereof are given in enclosed Statement.

(c)&(d) As per observations made by the CGWB, significant decline in the levels of ground water have been observed in certain pockets in the States of Andhra Pradesh, Assam, Bihar, Chhattisgarh, NCT of Delhi, Jharkhand, Gujarat, Haryana, Karnataka, Kerala, Madhya Pradesh, Maharashtra, Orissa, Punjab, Rajasthan, Tamil Nadu, Tripura, Uttar Pradesh and West Bengal.

Studies undertaken to monitor effects of the artificial recharge schemes have shown positive impact in terms of rise in ground water level and sustainability of ground water structures in the areas where such schemes have been implemented.

(e)&(f) The Government is encouraging rain water harvesting activities through mass awareness and training programmes by involving various Government and Non- Government organisations. During 2003-04, the CGWB has a programme to organise 51 training programmes and 51 mass awareness programmes on rain water harvesting in the country.
