## ANSWER

THE  MINISTER  OF  STATE  FOR  WATER  RESOURCES, RIVER  DEVELOPMENT  AND  GANGA REJUVENATION & PARLIAMENTARY AFFAIRS

( SHRI ARJUN RAM MEGHW AL )

(a) & (b) Central Ground Water Board (CGWB) periodically assesses annual replenishable ground resource  availability  of  the  Country  jointly  with  the  State  Governments.    As  per  the  lat (2013), out of the total 6584  assessment units (Block/ Taluks/ Mandals/ watershed/ Firkka) in the Country (including Rajasthan), 1034 units have been categorized as 'Over -exploited'.  State - wise details are given at Annexure -I.

Further, CGWB also generates ground water quality data on regional scale once in a yea as part of various scientific studies.  As per the studies, ground water contamination has be isolated  pockets  in  parts  of  various  States  of  t he  Country  including  Rajasthan.  State - wise  details  of contamination of ground water are given at Annexure -II.

- (c)    The  assessment  of  ground  water  resources  in  the  Country  by  CGWB  and  States  invol quantification of annual ground water availability which can be extracted for irrigation without adversely affecting the resource availability and thereby not causing long - term decline of water table.  Details are  at Annexure -III. Based on the ground water availability for future irrigation use in an assessment unit, the number of tube wells feasible in the unit can be calculated.
- (d) Water  being  a  State subject, regulation &  conservation  of  ground  water  is primarily States' responsibility.    However,  s teps  taken  by  the  Central  Government  for  conservation  of  ground  wate available at the following URL http://mowr.gov.in/sites/default/files/MeasuresForGW - Depletion\_1.pdf :
