Is the EPA under-estimating the depth of the problem at its West Lake Superfund Site?

In 1979-1980 Gary Schneider hauled Bridgeton municipal waste to West Lake Landfill for BFI. He says the quarry pit was 75-feet deep then —  seven years after B&K Construction illegally dumped tons of radioactive waste at the same site.

The EPA has recommended excavating and cleaning up the same site to a maximum of 16-feet.
