Pat McNamara writes in Nuclear Genocide in Canada:
"Taxpayers will have to foot the bill to remediate the abandoned uranium mines in Canada whose owners simply walked away. Many other mines simply dumped their radioactive tailings in the closest lake. These radioactive tailings ponds are contaminating downstream environments. In most cases, the tailings ponds are contained with simple earthen dams. There have been more than 30 breaches of the earthen dams at Elliot Lake since they were first put in place."
