Land contamination can result from activities conducted by a wide range of industries. ​The environmental and legal liabilities arising can be costly and with significant public relations effect.

​Management of both explicit and hidden risks prevents further degradation of soil and groundwater while minimising the resulting impacts on human health and the environment.
