Language openings emphasize different things.
Something to inspect — not a judgment of bias or bad faith.
Overview
Use this briefing to choose what to inspect. The tabs contain the underlying comparisons.
Open the live English Wikipedia article ↗L1 ran on this article and exact checking did not confirm a durable rewrite. This does not mean the article never changed.

Did editors fight over it?
The page was not dominated by back-and-forth undoing. A quiet rewrite can still matter — it just means few people fought it on the page. About 7,900 recorded revisions in the measure.
Who wrote today’s text?
Half of the wording still on the page is about 7.2 years old or newer. 15.1% was written in the last 3 years. The ten most active accounts wrote 40.0% of what is there now (authorship is more spread out; 706 different accounts overall). Snapshot data on this page runs through 2026-01-01.This is background only — a small group of writers is common on specialist pages.
Available evidence: Rewrite (no candidate found), Citations, Framing, Facts, Versions.
Not available in this export: Vocabulary. Missing coverage is not a negative finding.
No candidate rewrite window was confirmed
The exact L1 check ran, but no candidate showed the required durable-spine drop. This is a completed negative result for that detector, not a claim that the article never changed.
Persistence-weighted changeThe share of wording lost, weighted so text that survived more snapshots counts more. by interval
Each row reports established wording lost, standing wording gained, and paired change as a replacement lead. The bar shows loss for continuity with earlier reports. Below-floor anomalies remain descriptive evidence but cannot receive exact confirmation. A coverage gap is shown descriptively but excluded from detector decisions. Candidate-window labels report the exact revision-level decision for the broader window containing that interval.

How the footnotes changed
How the article's own footnotes changed across the rewrite: which websites and books were cited more or less. We only show the mix — we do not rate sources as good or bad.
Looking at 2002-01-01 → 2026-01-01 (no L1 pivot — whole history): 137 websites were cited more (or newly), 0 less (or dropped). Number of footnotes: 0 → 241. Different websites: 0 → 137.
Mix of citation types: — → web 39%, journal 28%, book 24%, news 7%, report 2%.

Cross-language lead comparison
How the opening of the article presents the topic in different languages. Disagreement is a reason to read carefully, not a final answer.
In this narrow time window, the English lead text remained textually identical before and after (only revision metadata differs), so no genuine English-side change occurred. The Arabic and Tamil leads also remained essentially unchanged in substance, with Arabic only adding a trailing image caption ('الماء'). Since English did not change, no temporal divergence (moving away, converging, or parallel change) can be established; the only persistent difference is the pre-existing gap in detail and figures between English (highly quantitative, ~1,460 Tt, 71% coverage, aquifer/vapor percentages) versus the much shorter Arabic and Tamil descriptions (basic definition, 70% coverage, no numeric detail), which predates and persists through this window.
Compared matched historical revisions around the confirmed rewrite from 2007-07-01 to 2008-01-01.
