The USA has agreed to take radioactive Palomares topsoil out of the province and transport it back to Nevada, to a storage facility just outside of Las Vegas.
The US Energy Dept sent the Spanish Nuclear Commission a cleanup plan back in July which the Spanish are prepared to accept to finally put an end to the problem, according to a leaked report.
The radioactive material comes from an incident 50 years ago next January when a US bomber carrying nuclear weapons crashed near Palomares, with the nuclear weapons breaking open and spilling their contents everywhere.
Although the US did take a large amount of soil away back then, negotiations stalled for the next 5 decades until just now. The Spanish reckon half a kilo of weapons grade plutonium is still dispersed across 50.000 square metres of land, enough soil to fill 30 Olympic sized swimming pools.

Oh Dear! Too little too late. What a sad species we are.
