Articolul 4

Member States shall use the procedure described in paragraph 2 to assess the chemical status of a body of groundwater. Where appropriate, Member States may group bodies of groundwater in accordance with Annex V to Directive 2000/60/EC when carrying out this procedure.

A body or a group of bodies of groundwater shall be considered to be of good chemical status when:

The Commission is empowered to adopt an implementing act to establish a list of pesticide metabolites that may be found in groundwater and for which an assessment of their relevance has been carried out in the Union, indicating whether they are relevant or not relevant, by 11 May 2028. The list shall not include metabolites assessed as being of no concern. The list shall be based on data generated during the process for approving active substances under Regulation (EC) No 1107/2009 of the European Parliament and of the Council ( 1 ) and Regulation (EU) No 528/2012 of the European Parliament and of the Council ( 2 ) and associated scientific output from the European Food Safety Authority (EFSA) and the European Chemicals Agency (ECHA), and, if available, new scientific data on existing metabolites or newly discovered previously unidentified metabolites. The Commission shall adopt an implementing act to update the list at least every six years. The implementing acts referred to in this paragraph shall be adopted in accordance with the examination procedure referred to in Article 9(2) of this Directive.

Choice of the groundwater monitoring sites has to satisfy the requirements of Section 2.4 of Annex V to Directive 2000/60/EC on being designed so as to a coherent and comprehensive overview of groundwater chemical status and to provide representative monitoring data.

Member States shall publish a summary of the assessment of groundwater chemical status in the river basin management plans in accordance with Article 13 of Directive 2000/60/EC.

This summary, established at the level of the river basin district or the part of the international river basin district falling within the territory of a Member State, shall also include an explanation as to the manner in which exceedances of groundwater quality standards or threshold values at individual monitoring points have been taken into account in the final assessment.

If a body of groundwater is classified as being of good chemical status in accordance with paragraph 2(c), Member States, in accordance with Article 11 of Directive 2000/60/EC, shall take such measures as may be necessary to protect aquatic ecosystems, terrestrial ecosystems and human uses of groundwater dependent on the part of the body of groundwater represented by the monitoring point or points at which the value for a groundwater quality standard or the threshold value has been exceeded.
