1. Gasoline is not the best choice for this process. The light hydrocarbons destabilize the agent of
solidification.
2. Heavy diesel and hydrocarbons are good candidates for stabilization because of their viscosity and
low speed of migration.
3. Other methods of environmental remediation are adapted in porous grounds.
4. Conditions of the underground medium and ground water can change these values.
