(e) if so, the details thereof and if not, the reasons therefor?

## ANSWER

## THE  MINISTER  OF  STATE  FOR  WATER  RESOURCES,  RIVER  DEVELOPMENT  AND  GANGA REJUVENATION

(DR. SANJEEV KUMAR BALYAN)

(a) As per information received, Central Pollution Control Board (CPCB) is monitoring ground water at 807 locations throughout the Country.  However no study has been conducted to identify percentage of pollution in ground water due to industrial wastes and pesticides.

The  ground  water  available  in  the  Country,  in  general,  is  potable  and  suitable  for  various  usage. However, localized occurrence of  ground water having various chemical constituents in excess of the limits prescribed  for  drinking  water  use  has  been  observed  in  almost  all  the  states.  The  commonly  observed contaminants  such  as  Arsenic,  Fluoride  and  Iron  are  geo-genic,  whereas,  contaminants  such  as  nitrates, phosphates,  heavy  metals  etc.  owe  their  origin  to  various  human  activities  including  domestic  sewerage, agricultural practices and industrial effluents.

In  view  of  the  increasing  concerns  about  the  deterioration  in  ground  water  quality  a  report  entitled 'Ground  Water  Quality  in  Shallow  Aquifers  of  India'  has  been  prepared  by  Central  Ground  Water  Board (CGWB).

(b) Ministry of Drinking Water and Sanitation (MoDWS) has informed that upto 67% fund allocated to the States  under  National  Rural  Drinking  Water  Programme  (NRDWP)  can  be  utilized  for  coverage  of  water quality affected habitations and for tackling water quality problems.

As  a  short-term  measure,  under  recommendations  of  NITI  Aayog,  Central  Government  as  one-time measure  has  released  Rs.  800  crore  on  100%  funding  basis  to  States  for  setting  up  of  Community  Water Purification Plants (CWPP) in habitations affected by Arsenic and Fluoride and another Rs. 100 crore each for the West Bengal and Rajasthan States to complete the ongoing water supply schemes in Arsenic and Fluoride affected  habitations.    As  a  long-term  measure,  MoDWS  has  launched  National  Water  Quality  Sub-Mission (NWQSM) for providing safe drinking water for Arsenic and Fluoride affected habitations and has released Rs. 814.14 crore during current Financial year for completing ongoing water quality affected schemes

(c)    As  per  the  ground  water  level  data  monitored  by  Central  Ground  Water  Board  (CGWB),  Pre-monsoon (April/ May, 2016) water level data when compared with the decadal average (2006-2015) indicate that 66% of the wells have registered decline in ground water level in certain pockets in all the States/UTs of the Country. State-wise details are given at Annexure-I.

(d) & (e)  Ground water data collected/ generated by State Ground Water Departments and CGWB is used to estimate  the  annual  replineshible  ground  water  resources  of  the  Country  periodically  using  a  well  defined methodology viz. Ground Water Resource Estimation Committee methodology (1997).  State-wise details are given at Annexure-II.
