A 1,300,000-square-foot (120,000 m 2) complex of mixed residential, office, retail and commercial space is being built on 15 acres (61,000 m 2) of former industrial land in downtown Victoria that was contaminated by lead. 10 tonnes of soil was treated with cement, which was mixed into the soil on site simply by using an excavator bucket. The ...
Deep soil mixing requires specialized auger mixing equipment. In order to apply this method in-situ and in deep soil, the oxidant must be pumped to the point of mixing using a kelly bar (a piece of earth drilling equipment), or appropriate piping to the place where the soil needs to be oxidized. The soil then has to be mixed by using mixing blades.

It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste .
The limitation or remediation of pesticides is the low bioavailability. [57] Altering the pH and temperature of the contaminated soil is a resolution to increase bioavailability which, in turn, increased degradation of harmful compounds. [57] The compound acrylonitrile is commonly produced in industrial setting but adversely contaminates soils ...
