drums were found in the back of an industrial site and Fig. 3.5 where storage facil-
ities are so poor that the contamination of the soil surface is already visible during
the site reconnaissance. Obviously, observations like these will result in sampling
locations for the Exploratory Investigation. Sampling locations that would not have
been selected in the sampling plan would be based on a Preliminary Investigation
without a site reconnaissance.
As the Preliminary Investigation, apart from a visit to the site, only consists of
studying archives, it is hard to assure that an investigator indeed has put sufficient
