 abstract={In the period of 1993-1998 six wells known as being contaminated were monitored 3-6 times per year (a total of 143 samples) for the presence of atrazine, simazine and respective chloro-dealkyl metabolites. Samples were prepared for analysis by solid phase extraction (SPE) and determination was by HPLC/UV or GC/NPD techniques, GC/MSD and HPLC/DAD were employed as secondary (confirmatory) techniques. Residues of analysed compounds were present in more than 90% of samples with exception for DeDiA that was found in 81.6% of samples. The highest concentrations of atrazine, simazine, DeA, DiA, and DeDiA were 16.80; 18.60; 7.49; 2.98 and 3.43 μgil respectively. New inputs of atrazine and simazine were observed in ground water of three wells occasionally, probably resulting from fresh herbicide treatments. In the other wells contamination was rather stagnant at lower levels (0.X mg/I).},
