Privacy-safe by design

The map receives only public geometry approved through governance. A displayed coordinate may represent a generalized location rather than the exact scientific coordinate.

Published evidence

No records loaded

Coverage is a count of published observations within 0.25° cells. It is not a groundwater-potential, aquifer-productivity or drilling-success map.

Published records only

The explorer never reads raw community submissions or private canonical coordinates.

Evidence coverage, not potential

Coverage cells summarize the density of published evidence. Empty cells mean insufficient public evidence—not absence of groundwater.

Verification remains visible

Bronze, Silver, Gold and Imported classifications stay attached to records so users can judge the strength and origin of evidence.
