Another method is excavation where the contaminated soil is taken away. This can work quite well but it is essential to ensure all contamination is removed or the efforts will not work.
Thermal or heat applies to the soil to kill the harmful substance may also work in some situations. Lastly, capping off the soil, which involves covering it may be the only ting to do.
