R. Kozel et F. Zwahlen, METHODICAL APPROACH FOR THE DETECTION OF PESTICIDES IN GROUNDWATER - A SWISS EXAMPLE, Eclogae Geologicae Helvetiae, 87(2), 1994, pp. 439-444
A methodical approach for the detection of pesticides in porous aquife
rs is summarised and illustrated on the basis of a regional study. The
process is mainly based on a sound knowledge of the three following e
lements: the hydrogeologic environment, data on the use of pesticide p
roducts and data on the behaviour of the pesticides in the soil and at
deeper levels.
