Contaminants included solvents, metals, pesticides, and miscellaneous manufacturing-related chemicals. In 1985 the Army permanently sealed the disposal well in stages. At that time, liquid waste disposal methods were employed in an attempt to prevent the chemical contamination from spreading further including lining one of the basins with asphalt, and injection of the waste chemicals into a deep well, but these techniques were ultimately unsuccessful.
