Abstract

The knowledge about pesticide residue in private wells is not well documented in Sweden.Previous studies have detected pesticide residue in private wells, this issue is what made themunicipality of Laholm commission the study. The purpose was to collect water samples from50 private wells in Laholm and have them analyzed for traces of pesticides. The wells in thestudy are spread geographical over the entire municipality. The analysis of the water sampleswas carried out by the accredited laboratory Eurofins. Nine of the 50 wells in this studycontained residue of pesticides and two of these exceeded the allowed concentration of 0,1 μg/l.Nine different pesticides were detected, among these were BAM, Atrazin and breakdownproducts from Metribuzin. These pesticides were mostly found in older dug wells. The result alsoindicates that occurrence of pesticide residue is more frequent in areas of agricultural activity.These areas should therefore be investigated further. Not all substances that were found are usedfor agriculture. Substances that have been banned for a long time were found in the samples.This highlights the importance of adequate control of new pesticides considered for commercialuse.
