Figure 3.6 illustrates 15 pesticides with the largest number of monitoring sites for groundwater and surface water, respectively. For groundwater, atrazine, simazine, desethylatrazine, diuron, and bentazone are the five most often reported pesticides in the dataset. In surface waters, 11 substances were reported as monitored at more than 6 000 monitoring sites.

I don't quite understand the title of this figure. Is this the numbe rof monitoring sites at which these individual pesticides were detected?
See previous comment under 3.1.1.1 - most of these substnaces are no longer authorised for use in the EU
Fig 3.6 shows organics that are not pesticides: 1,2-dichloroethane, trichloroethane, carbon tetrachloride
some of the AS shown are banned since many years in teh EU (atrazine, DDt, etc), however they are persistent in the enviroment and therefore obviously they will continue to appear in samples. This would need to be explained somehow (at least adding footnotes).
Please consider checking teh whole report according to this observation. Thank you
