## ANSWER

## THE MINISTER OF STATE FOR JAL SHAKTI (SHRI PRAHLAD SINGH PATEL)

(a) Bureau of Indian Standards IS-10500: 2012 specifies 'acceptable limit' and 'permissible limit  in  the  absence  of  alternate  source'  for  various  physio-chemical  and  bacteriological parameters for drinking water quality as provided in the Annex-I.

To make provision of potable tap water supply in adequate quantity, of prescribed quality and on  regular  &  long-term  basis  to  every  rural  household  by  2024,  since  August,  2019, Government of India in partnership with States, is implementing Jal Jeevan Mission (JJM) Har Ghar Jal. Under Jal Jeevan Mission, as per existing guidelines, IS:10500 is to be adopted for ensuring safe drinking water supply.

States/ UTs have been advised to carry out testing of drinking water sources once in year for chemical  and  physical  parameters,  and  twice  in  a  year  for  bacteriological  parameters.  To enable  States/  UTs  to  test  water  samples  for  water  quality,  and  for  sample  collection, reporting,  monitoring  and  surveillance  of  drinking  water  sources,  an  online  JJM  -  Water Quality Management Information System (WQMIS) portal has been developed. The Statewise details of water quality test reported through WQMIS is available in public domain on JJM Dashboard and can also be accessed at:

This portal also provides automated alerts to concerned authorities in States/ UTs, if the water sample tested is contaminated, to initiate remedial actions. On this portal an individual can also register his sample and choose nearby water quality testing laboratory to get the water sample tested.

(b)  to  (f)  Drinking  Water  being  a  State  subject,  it  is  States  who  plan,  design,  approve  and implement  drinking  water  supply  schemes  including  to  set  up/  strengthen  labs  &  to  make available required human resources in labs. The staff positions in laboratories may be filled with regular/ contractual personnel or can even be outsourced following due procedure as per extant rules of respective State/ UT.

The district-wise details of drinking water quality testing laboratories in Madhya Pradesh is at Annex-II.

The State-wise details of water samples tested in laboratories is at Annex-III.

The  States  may  take  up  appropriate  water  treatment  system/  technology  depending  upon techno- economic feasibility. As such details of individual projects/ schemes for rural water supply projects are not maintained at the Government of India level.
