The recent stimulus package passed by Congress and signed by the President included money to aid existing Superfund cleanups, especially orphan sites, to the tune of $600M. This NY Times article discusses the situation by highlighting an orphan site in NJ.
Congress and the President intend to reinstate the defunct Superfund tax. Money from the tax would advance EPA's other missions of finding polluters, holding polluters accountable for their actions, and cleaning up sites. It will help relieve the financial burden from the taxpayers.
Regardless of the fate of the Superfund tax, it's good to see stimulus money putting shovels in the ground for the good of everyone.
