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.
In Hungary, the governmental decree on quality standards
of groundwater and geological agent protection (KöM-EüM-FVM-KHVM
Decree No. 10/2000. (VI.2.)) orders that the environmental
qualification of pollutions and their effects has to be
based on the limit values set out in Annex 2.
Site investigation and soil sampling has to be carried
out in accordance to the MSZ 21470-1:1998 Standard. This
Standard contains the basis and methodologies of soil sampling
in any environmental soil assessment including general
instructions, site investigation and sampling requirements.
