Pesticide Atlas — SNO: Sum of standard exceedances 19115

The map shows the overall picture of the amount of pesticides in surface water. The Som Standard Overruns (SNO) is a standard overrun of the surface water based on the number of different pesticides exceeding the standard and the size of that exceedance. The larger the SNO (red and purple dots) the more and the larger there are exceedances. For grey dots no SNO has been calculated (because insufficient substances have been measured. The map comes from the Atlas Pesticides in surface water (www.bestrijdingsmiddelenatlas.nl). This atlas was funded by the various ministries (IenM and EZ), the Directorate General Water, with the cooperation of UvW, RIVM, Ctgb and Rijkswaterstaat — WVL. The data was created by the large measurement effort that our Dutch water managers provide every year. The data was collected through IHW.
