In France, 15 million analyses have been collected since 1997. These data are hard to interpret, partly because the surveillance is carried out under multiple monitoring networks. Each network has its own purpose (general knowledge of water quality, control of drinking water standards, or specific knowledge of pesticide contamination) and area of concern, leading to different monitoring strategies in terms of sampling date, location and rate. Methods of interpretation of pesticide contamination monitoring data by grouping data on a geographic basis are interesting to describe contamination and link it to pesticide applications (dates, regions and quantities). Comparison with quantities sold highlights substances and regions with comparatively high contamination.
