## TESTING OF DRINKING-WATER SAMPLES

## 6317.   DR. KAKOLI GHOSH DASTIDAR:

Will the Minister of JAL SHAKTI be pleased to state:

(a)  the  number  of  drinking  water  samples  tested  and  the  number  of  samples  out  of  those  found contaminated during the last three years, year and State/UT-wise;

(b) the list of areas flagged repeatedly, district-wise and the remedial actions taken along with timelines set in this regard for the purpose; and

(c) whether the Government would place a public dashboard of contaminated sample trends and action taken reports and if so, the details thereof, State/UT-wise?

## ANSWER

## THE MINISTER OF STATE FOR JAL SHAKTI (SHRI V. SOMANNA)

(a) to (c) The Jal Jeevan Mission (JJM) - Har Ghar Jal, was launched in August 2019, in partnership with States/ UTs to make provision of potable tap water supply in adequate quantity, of prescribed quality and on regular & long-term basis to rural households. Drinking Water being a State subject, the responsibility of Planning, Designing, Approval, Implementation, Operation & Maintenance of drinking water  supply  schemes,  including  those  under  the  Jal  Jeevan  Mission,  is  vested  with  State/UT Governments. The Government of India supplements the efforts of the States by providing technical and financial assistance.

Under the Jal Jeevan Mission (JJM), to enable States/ UTs to test water samples for water quality, and for sample collection, reporting, monitoring and surveillance of drinking water, an online JJM - Water Quality Management Information System (JJM-WQMIS) portal has been developed. The State-wise details of water quality testing, contamination reported and remedial action taken at village level as reported through WQMIS are available in public domain and can be accessed at: https://ejalshakti.gov.in/WQMIS/Main/report. The State/ UT-wise details of numbers of drinking water samples tested during 2023-24, 2024-25 and 2025-26 (as on 31.03.2026) are annexed .

In consultation with various stakeholders 'Concise Handbook for Monitoring Water Quality of Piped Drinking Water Supply to Rural Households' has been  released in December 2024 for guidance to States/ UTs. This handbook recommended for a comprehensive testing of drinking water samples at various  testing  points  such  as  source,  treatment  plant,  storage  and  distribution  points,  and  remedial action wherever necessary, to ensure that the water supplied to households is of prescribed quality.

Further, as per this Handbook, it is envisaged that based on the geogenic situation and contamination found in a specific region, SWSM should carefully consider and declare the list of parameters that should be included in the water quality monitoring & surveillance activities of PWS for the rural areas.

State  Water  &  Sanitation  Mission  (SWSM)  Dashboard  and  District  Water  &  Sanitation  Mission (DWSM) Dashboard have been developed on the JJM-IMIS portal for monitoring of various aspects of progress made under JJM at the State level and District level respectively. Both the Dashboards display water quality monitoring data including reported contaminated samples and remedial action taken.

A 'Citizen Corner' has also been placed on the JJM Dashboard. The 'Citizen Corner' includes display of village level water quality test results in the public domain to further create awareness and build confidence among people about the quality of water supplies through the PWS in rural areas.

Ministry of Housing and Urban Affairs (MoHUA) has informed that as reported by the States/UTs on the AMRUT 2.0 platform during the period from 1st January, 2024 to 31st December, 2024, a total of 3,32,170 water quality samples out of 3,35,278 samples tested at WTPs and 22,18,838 samples out of 22,45,200 samples tested at the household level in urban areas were found compliant for the parameters E. coli, Arsenic and Fluoride. State-wise details of water quality testing in urban areas are available at the website https://amrut.mohua.gov.in/wqa/dashboard. MoHUA has also published Manual on Water Supply and Treatment Systems (Drink from Tap) in March 2024 for reference by the States/ ULBs for designing,  implementation,  drinking  water  quality  and  monitoring  of  the  water  supply  projects. (https://mohua.gov.in/publication/manual-on-water-supplyandtreatment-systems---drink-from-tap--march-2024.php).

Further, MoHUA has issued an advisory "Strengthening Water Quality Monitoring in Cities through Community Participation" under AMRUT 2.0 in November, 2024 to all the States to formulate a Water Quality Monitoring strategy at the State or City level and to strengthen the institutional capacity for citywide monitoring of drinking water quality in urban areas along with Digital Display Boards for water quality parameters for public information & awareness.

Central Ground Water Board (CGWB) has informed that it undertakes groundwater quality assessment based on analysis of groundwater samples collected through its monitoring programme. The chemical analysis data generated through this monitoring is published in the Annual Ground Water Quality Report -2025  and  is  available  on  the  CGWB  website.  The  report  contains  State/UT-wise  details  of  the number/percentage of groundwater samples found above permissible limits for various parameters such as Electrical Conductivity, Fluoride, Nitrate, Iron, Arsenic, Uranium and others.
