Description:
This work presents the results of an assessment of the existence and concentration of 13
volatile organic compounds (VOCs) in groundwaters from 14 hydrological basins in Sicily
(25,710 km2). On the basis of hydrological, hydrogeochemical and geological studies, 324
sampling points were selected. All groundwater sampled were collected twice, from
October to December 2004 and from February to May 2005, and were analysed to determine
the concentration and spatial distribution of the VOCs in the aquifers. The need to analyze
a large number of samples in a short space of time so as to obtain quantitative analyses in
trace concentration levels spurred us to create a new analytical method, both simple and
sensitive, based on HS-SPME/GC/MS. The concentrations of VOCs measured in industrial
and intensive agricultural unconfined aquifers were greater than those found in other
aquifers. Tetrachloroethylene, chloroform, trichloroethylene and 1,2-dichloropropane
were the most frequently detected VOCs. However, they exceeded the guideline values
proposed by the EU in only three aquifers located near to industrial and intense agricultural
areas.
