In-Depth Information
the assessed vulnerability of the confined Eocene aquifer is significantly lower as
compared with that of the upper Quaternary aquifer.
The zones of Quaternary aquifer vulnerability show significantly higher
groundwater vulnerability to contamination with
137
Cs as compared with previous
assessments performed with no account of PFMZs [
Shestopalov
, 2003]. This
proves once more the importance of PFMZ input into upper groundwater
contamination by the infiltration of a contaminant from the surface. The results
of the groundwater protectability assessment for Chernobyl-related radioactive
contamination obtained with use of the developed methodology (with PFMZs
taken into account) are in much better correlation with field data of groundwater
contamination by
137
Cs [
Shestopalov
, 2001] than previously obtained with no
account of PFMZs [
Belousova and Galaktionova
, 1994;
Belousova
, 2005] with no
account of PFMZs.
