Abstract

Potentially polluted site is made to be sampled at different stages of its
characterization or remediation, to meet various objectives. In all cases, the problem
of the sampling strategy in terms of “how to reach a sufficient level of knowledge
relative to study objectives, with a minimum data positioned better?” Speaking of
sampling strategy means then also take into account financial constraints or deadlines,
decide of the sample sizes appropriate to the objectives of study, to program
the sampling phases in order to best resolve uncertainties or to integrate all existing
data to determine the number and location of additional samples. Currently, sampling
strategies most often result of a reflection of practitioners based on their experience,
knowledge of the site as well as common sense. The objective of this work is to show
what can be the contribution of geostatistics to rationalize sampling of polluted sites.
Through the use of database collected during a project of research estimation and
evaluation of the risk of spreading the pollution of ground water, emitted by a plant
of paintings [2]. The Algerian regulations do not provide specific recommendations
on the sampling methodology. The Algerian methodological guide recalls the different
approaches of the points location and refers to the recommendations developed
by the U.S. EPA in 1991 [5] and by the european standardization [1]. The site in
question has a multiple pollution (three pollutants) on an area of about 5 ha of land.
It is a plant of paintings located in north eastern Algeria, where various chemicals
containing heavy metals were dumped for many years from the 80 s. Between the
years 2008 and 2010 a study was carried out on this site to locate and study the special
distribution of soil contamination by heavy metals.
