   Sammanfattning : From a small stream draining an agricultural catchment area in south Sweden, a temporal analysis of the occurrence of legacy pesticides was carried out and correlated with contemporary groundwater levelling, precipitation and flow rate of the stream, in order to evaluate groundwater outflow as an entry route for pesticides in the stream. Based on continuous measurement data from two periods of 12 respectively 16 months, in total eight legacy pesticides and three metabolites of legacy pesticides, were detected from early spring to late autumn, when runoff water to the stream was low and groundwater constituted the main water source of the stream.
