Pressures and impacts causing failure to achieve good status

For surface water bodies, the main significant pressures are hydromorphological pressures (41 %), atmospheric deposition and diffuse source pollution (37 %), followed by point source pollution (18 %) and water abstraction (7 %) (Figure 6.2). Atmospheric deposition is mainly reported for water bodies failing good chemical status due to mercury.

The main impacts on surface water bodies are chemical pollution (50 %), followed by altered habitats due to morphological changes (40 %) and nutrient pollution (29 %).

Figure 6.2: Overview of the proportion of surface water bodies having A) main significant pressures and B) impacts in the second RBMPs.

Note: Pressures from diffuse sources do not include atmospheric deposition. The diagrams show the proportion (%) of water bodies affected by each pressure and impact type for the second RBMPs, considering only water bodies which have been classified with respect to ecological status (106 329 water bodies) .

    BE-FLA (RV): p. 57 For surface water bodies, the main significant pressures are hydromorphological pressures (41 %), atmospheric deposition and diffuse source pollution (37 %), followed by point source pollution (18 %) and water abstraction (7 %) (Figure 6.2). Atmospheric deposition is mainly reported for water bodies failing good chemical status due to mercury.

    1) p.31: 40% - 38% - 18% - 7%

    2) Why to mention “water abstraction (7%)” separately, since it is already included in HYMO pressures?

    BE-FLA (RV): p. 57, Figure 6.2. Note: Pressures from diffuse sources do not include atmospheric deposition.

    Is confusing. Compare with Fig 2.9 on p 32

    deposition... (40%)

    SK: Page 57, 1st paragraph: Make sentence more clear by adding also percentage for atmospheric deposition in the brackets. Otherwise, the sentence could be understood that atmospheric deposition and diffuse source pollution together achieve 37 %.

    SK: Figure 6.2 and 6.4 (left part of the figures) - Sort the significant pressures by increasing percentage.

    (AT) 1st sentence: hydromorphological pressures (41  %),

    The number does not fit to tab. 2.8. or?
