(b) the list of areas flagged repeatedly, district-wise and the remedial actions taken along with timelines

(c) whether the Government would place a public dashboard of contaminated sample trends and action

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.
Page 1 of 3Further, 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.
