Guides are article candidates, events are source-supported reports, and facts are reviewed records. Countries and industries overlap; grouped counts cannot be added into a global total.
Country × industry coverage
Select a cell to inspect its records. Coverage measures published material, never market size, factories or local project volume.
A dash means coverage is unknown or unconnected. A verified zero is shown only when the metric scope is known.
Daily public additions
First verified public appearance in this library, by UTC+8 day. Source publication dates do not create historical growth.
History is accumulating. Missing or failed days remain gaps; a single snapshot cannot establish a trend. Historical baseline and backfill are labelled separately.

Recent reported developments
Source publication and first public verification are separate dates. Reported developments remain observations.
No source-supported events are public for this selection.
Comparable water samples
Compare only matching parameter, unit, water stage and scope. Individual facility samples never represent a national average or a continuous water-quality trend.
No group of at least two comparable, reviewed samples is available. Read individual evidence in the published dossiers.
Move from evidence to a treatment discussion
Carry the selected country and industry into your enquiry. Confirm influent conditions, discharge destination and operating scope with the engineering team.
