Open intelligence for contaminated land

Forty industrial and mining sites. Twenty depopulated towns. One map.

Each coloured circle is a contaminated site in Spain scored 0 to 100 for phytoremediation viability. Greener means a faster, cheaper cleanup.

Each purple square is an abandoned or shrinking town near contamination. As the land is restored, these are the places that could come back.

Click any marker for the contaminant inventory, score breakdown, climate-adjusted remediation forecast, and the nearest repopulation opportunity.

High viability ≥ 70 (fast cleanup path)

Medium 40 to 69 (mixed approach)

Low < 40 (severe, slow, expensive)

Abandoned or depopulated town

All data derived from open Spanish public records. Open methodology, open code. Every build funds the cleanup.
