Eight police officers linger with their backs to the two-hectare (five-acre) site known as Stocamine. The place is nondescript in the morning drizzle: two mine shafts, some modern-looking office buildings, a staff car park, lines of landscaped trees. The reason for the police presence, however, is what lies beneath: 42,000 tonnes of toxic waste stored under our feet.
Stocamine, which lies in the old industrial town of Wittelsheim, Alsace, once held an old potash mine. Now, the mine shafts are closed, storing poisonous waste from elsewhere. Above the mine shafts is one of Europe’s largest aquifers.
