But a report produced by the Alliance for Nuclear Accountability found:
Approximately 18 million cubic feet of radioactive and chemical solid wastes onsite were disposed of since 1943. “All of the radioactive waste and most of the chemical waste have been buried on the mesas of Pajarito Plateau where LANL is located. Radioactive liquid wastes were discharged to the canyons, initially with little treatment.”
For many years, one method of disposal was “kick-and-roll”. The back of a truck was brought to the edge of a hole and barrels of waste were kicked. Wherever the barrels rolled tow as their final resting place.
