Dear all,
I’m
doing research about the
contamination of the soil around Ypres in West-Flanders (Flanders
Fields, Belgium)
where
I have to investigate in a geostatistical way whether the present
pollution is
caused by industrial or World War I activities. At the moment there are
only
visual indications that the pollution is due to World War I activities
because of
the following reasons:
1)
A
diffuse instead of a point source pollution over a
large area with a pattern that follows more or less the frontlines
situated in the
warzone.
2)
A
copper and lead pollution (caused by Shrapnell
shells used during the war??) without the presence of any other heavy
metal
pollution (for example zinc) which indicates that the pollution is
probably not
industrial related.
3)
There
are no industrial activities in the investigated
region.
My
question is how I can prove
in a geostatistical way that the pollution is caused by war activities.
I
already thought of using variography to compare the variogram of the
Flanders
Fields region with the variogram of a typical industrial site for the
heavy
metals copper and lead. Secondly I would compare the values, acquired
by making the difference between the concentration values of
copper/zinc and lead/zinc available at the same locations, of
the Flanders Fields with
these of the industrial site. I don't know if I first have to classify
the concentration values and work further on with the classification
numbers to make a good comparison...
Are
there any other and scientific more
correct methods to make a good discrimination between industrial and
war-related heavy metal soil pollution?
Thanks
in advantage,
