Inquiry: Sources for Indian River Water Quality Data

[Kuldeep2822k]

Body

I have been searching for water quality data for rivers across India. While I found some repositories (like the 2009-2012 CPCB datasets), the data is significantly outdated for my current analysis.

What I am looking for:

• Data from 2021 to 2025.
• Specific parameters: pH, Dissolved Oxygen (DO), BOD, and Coliform levels.
• Coverage: Major rivers like Ganga, Yamuna, Brahmaputra, etc.
  Does anyone know of any GitHub repos, APIs (like India-WRIS), or official CPCB portals that provide CSV/JSON downloads for more recent years?

Guidelines

• I have read and understood this category's guidelines before making this post.

For recent water quality data (2021–2025) in India, you should move away from static GitHub repos and look at these live institutional portals:

1. India-WRIS (Water Resources Information System): indiawris.gov.in is your best source for structured data. It has a dedicated 'Water Quality' module where you can filter by basin (Ganga, Yamuna, etc.) and download data for pH, DO, and BOD. They have improved their export tools recently, making CSV/Excel downloads much easier.
2. CPCB Real-Time Dashboard: Instead of the old PDF reports, check the Environmental Data Bank on the cpcb.nic.in portal. They now provide data from Continuous Real-time Water Quality Monitoring Stations (RTWQMS) which covers exactly the 2021-2025 window you need.
3. National Water Informatics Centre (NWIC): Visit nwic.gov.in. They act as a central repository and often have cleaner datasets than the raw CPCB logs.
4. Open Government Data (OGD) Platform: data.gov.in frequently hosts CPCB datasets. Search specifically for "River Water Quality" and sort by "Last Updated" to find the 2023-2024 releases.

Quick Tip: 2025 data might still be 'provisional' in some stations. If you need API access, India-WRIS is the only one currently offering semi-automated data retrieval through their dashboard.

For recent datasets (2021-2025), I recommend checking the India-WRIS (Water Resources Information System) portal directly, as they have an API for real-time monitoring.

Also, the CPCB's 'ENVIS' portal often hosts more updated reports than their main site. If you can't find a direct CSV, look for their 'Live Water Quality Data' dashboard—sometimes you can intercept the JSON response via the browser's Network tab (DevTools) or use a simple Python scraper to pull the latest tables.

Good luck with your analysis!

• OpenWeatherMap: Has some water parameter data
• Google Dataset Search: site:kaggle.com OR site:github.com Indian river water quality

GitHub repos:

• Search GitHub for "India water quality" or "CPCB dataset"
• Some researchers publish processed datasets on GitHub

Research Databases:

• Zenodo.org: search "Indian river water quality"
• ISRO GIS datasets
• Academic repositories from Indian research institutes

Most recent certified data (2021-2025) comes from CPCB monitoring stations. Direct CSV downloads are often available from cpcb.nic.in/download section.
