Slovenia's main military training area at Pocek is located in the mountaino
us Javorniki Watershed. This is a karstic district without surface drainage
or river valleys. The typical landscapes are conical hills and plateaus wi
th many dolines. The lithology, tectonic structure and speleological data i
ndicate a typical karst aquifer with underground water moving rapidly throu
gh fissures and conduits. Little attenuation occurs in such conditions and
as a result there is a high risk of pollution. Tracer tests have shown that
a significant proportion of the water recharging the Malni and Vipava spri
ngs comes from the vicinity of the military training area. As a result any
polluting activities taking place within the military training area are Lik
ely to affect the two springs. This is a very serious matter as the springs
have been developed to provide the water supply for the population of sout
h-western Slovenia.
