Site investigation describes the process of carrying out
investigations on land to determine whether there is contamination
present and to collect sufficient, suitable data for the
purpose of risk assessment. The investigation is normally
carried out in several stages. These stages range from a
desk study and simple visual inspection to full intrusive
investigation using trial pits and boreholes etc and the
sampling and analysis of materials.
Germany prefer a stepwise approach for site investigation.
In order to systematically identify and record all these
sites as quickly as possible, an approach was developed
which first of all evaluates only the available information
on specific sites and makes an initial formalised assessment
on the basis of these data.
The wording is slightly different in each state but the
approach contains the following steps:
* Historical Investigation
* Orientating Investigation
* Detailed Investigation
