Methodology & Sourcing

Source: data.gov.in (CPCB Rivers)
Granularity: state
Unit: stretches
Update cadence: Refreshed daily by an automated ingest (/india/api/ingest/water-resources), but the upstream resource is a fixed CPCB assessment dated November 2022 — the daily re-fetch does not create newer history than the source publishes.

Known caveats

Counts river stretches CPCB classified as polluted by water-quality sampling, not every river in a state.

Fewer polluted river stretches generally means better river water quality.
