The 618-10 Burial Ground is a 7½-acre waste burial ground that received low-to- high activity radioactive waste generated from Hanford’s 300 Area laboratories and reactor fuel development facilities.

During the years of operation from 1954 to 1963, waste was disposed of in 12 trenches and 94 vertical pipe units. Eighty of the units are made up of five bottomless 55-gallon drums welded together end-to-end, and corrugated steel pipes. The remaining 14 units are constructed of heavy-gage steel piping and were more complex to remediate.

Cleanup of the 618-10 Burial Ground was completed in 2018.
