Task: Empty a tar pit and dispose of materials at a former gas works
Time frame: November 1998 to February 1999
Substances: 150 tons of tar residues, 1,750 tons of soil and construction debris
Luckenwalde gas works
At the Luckenwalde gas works site where tar, gas, and coke were formally produced, a tar pit complex containing tar residues, contaminated soil, and construction debris had to be cleaned and decommissioned.
Information
Construction debris had been dumped into the tar pits. The pit cover was taken off and the tar was removed from the three pits by normal excavation and loaded into conical receptacles. Af-ter the tar residues were removed and disposed of, the pits were backfilled, compacted, and sealed. The tar water that had accumulated in the foundations of the gas tank holders was pumped out and disposed of.
Before the final cleaning of the area, sludge and sediments had to be disposed of along with the lightly to heavily contaminated excavated earth and recovered construction debris.
