| 32 | Following the approval of the project at issue, the claimants in the main proceedings, who are subject to expropriation or have a domestic well within the area covered by the project for their private water supply, have brought an action before the referring court, the Bundesverwaltungsgericht (Federal Administrative Court, Germany), against the contested decision. In that context, that court is required to carry out a full examination of the lawfulness of that decision. |

In that context, that court is required to carry out a full examination of the lawfulness of that decision.

| 33 | In that regard, the Bundesverwaltungsgericht (Federal Administrative Court) notes that, before the construction plan was approved, the bodies of water were not subject to any documented monitoring relating to the protection of the bodies of water concerned. |

In that regard, the Bundesverwaltungsgericht (Federal Administrative Court) notes that, before the construction plan was approved, the bodies of water were not subject to any documented monitoring relating to the protection of the bodies of water concerned.

| 34 | It is true that the authorising authority stated that, during the consent procedure, the bodies of water concerned had been monitored. However, it was not until the judicial proceedings were underway that that authority provided a technical study on water drainage, totalling 48 pages, describing the bodies of water concerned and the impacts of the project at issue on their qualitative elements (‘the technical study on water drainage’). For that reason, the referring court takes the view that the public was not sufficiently informed of the environmental effects of the project at issue during the course of the consent procedure, which, therefore, is vitiated by a procedural defect. |

| 35 | In the present case, however, according to the Bundesverwaltungsgericht (Federal Administrative Court), that procedural defect is not such as to lead to annulment of the contested decision since it had no effect on the meaning of that decision. In those circumstances, under the applicable German law, a procedural defect of that kind cannot be invoked by an individual claimant and may result in the annulment of the decision granting authorisation for the plan only if that claimant has actually been deprived of the opportunity to participate in the decision-making process. |

| 36 | Next, the referring court expresses uncertainty as to whether it is precluded that the monitoring relating to the prohibition of deterioration of the bodies of water concerned by a project may take place only after the approval decision has been adopted. It considers that Directive 2000/60 could require such monitoring to be carried out before that point as part of a transparent administrative procedure. This would mean that it is not for the courts, in judicial proceedings, but rather for the competent administrative authorities to take the necessary steps and to prepare the requisite documentation. |

| 37 | If that interpretation of Directive 2000/60 were to be accepted, the referring court considers that it must decide whether, in the case in the main proceedings, the administrative procedure should be reopened in order for a fresh public consultation to be carried out. |

If that interpretation of Directive 2000/60 were to be accepted, the referring court considers that it must decide whether, in the case in the main proceedings, the administrative procedure should be reopened in order for a fresh public consultation to be carried out.

| 38 | In that context, it would be necessary to answer the question whether the documents made available to the public under Article 6 of Directive 2011/92 must systematically include a report on compliance with the legislation on water quality. The Bundesverwaltungsgericht (Federal Administrative Court) takes the view that, in the case where a developer carries out a check of the conditions laid down in Directive 2000/60, the report that it submits to the authorising authority should be regarded as one of the ‘main reports’ within the meaning of Article 6(3)(b) of Directive 2011/92 and should, therefore, be accessible during the public consultation phase. |

| 39 | However, according to the case-law of the Bundesverwaltungsgericht (Federal Administrative Court), further public participation is not always necessary. In the present case, the technical study on water drainage was not drafted until after the delivery of the judgment of 1 July 2015, Bund für Umwelt und Naturschutz Deutschland (C‐461/13, EU:C:2015:433), and, therefore, after the public consultation phase. In that very specific situation, fresh public participation may be dispensed with ina smuch as the various documents that were accessible to the public before the project was approved satisfy two conditions. First, those documents must, in essence, contain the same information as a report that, in the light of the criteria laid down in Directive 2000/60, examines the effects of the project on the water. Secondly, the available documents and that report must arrive at the same conclusions. |

| 40 | Furthermore, the referring court takes the view that the obligation to prevent deterioration of the status of bodies of water relates to both surface water and groundwater and that considerations resulting from the judgment of 1 July 2015, Bund für Umwelt und Naturschutz Deutschland (C‐461/13, EU:C:2015:433), in respect of surface water can be broadly transposed to groundwater. However, in order to determine whether or not there is a deterioration of the chemical status of a body of groundwater, Directive 2000/60 distinguishes only between ‘good status’ and ‘poor status’. Furthermore, in accordance with point 2.4.5 of Annex V to that directive, a deterioration found locally may be taken into account only if it affects the body of water concerned as a whole. |

| 41 | Having regard to the judgment of 1 July 2015, Bund für Umwelt und Naturschutz Deutschland (C‐461/13, EU:C:2015:433), the referring court is of the opinion that a deterioration of the chemical status of a body of groundwater occurs in two situations: first, where at least one of the quality elements referred to in Annex V to Directive 2000/60 fails to meet one of the applicable parameters because of the project and, secondly, where the concentration of pollutants already exceeding a limit value in force increases further. |

| 42 | With regard to the limit values in force, the Bundesverwaltungsgericht (Federal Administrative Court) takes the view that reference should be had to Directive 2006/118, but that, in the present case, no deterioration of bodies of groundwater could be found. |

| 43 | Finally, the referring court considers that the obligations to prevent the deterioration and to enhance the status of bodies of water, referred to in Article 4(1) of Directive 2000/60, do not mean that all members of the public concerned by a project and who allege that their rights have been infringed are entitled to challenge a decision which fails to meet those obligations. Under the applicable German law, an action brought by an individual applicant is admissible only if that applicant invokes the infringement of provisions intended at least in part to protect his or her own rights. |

Under the applicable German law, an action brought by an individual applicant is admissible only if that applicant invokes the infringement of provisions intended at least in part to protect his or her own rights.

| 44 | Both the obligation to prevent deterioration of the status of bodies of water and the obligation to enhance those bodies of water must be complied with by the public authorities. However, those obligations do not, in German law, confer any subjective right on individuals who may be concerned by the impact that a project may have on the water. Those obligations establish water-management objectives and serve exclusively the public interest. |

Those obligations establish water-management objectives and serve exclusively the public interest.

| 45 | In that regard, it follows from the judgments of 15 October 2015, Commission v Germany (C‐137/14, EU:C:2015:683), of 8 November 2016, Lesoochranárske zoskupenie VLK (C‐243/15, EU:C:2016:838), and of 20 December 2017, Protect Natur-, Arten- und Landschaftsschutz Umweltorganisation (C‐664/15, EU:C:2017:987), that it is sufficient that environmental protection associations have the opportunity to verify compliance with EU environmental legislation which serves the public interest. That view of the right to bring proceedings corresponds to that laid down in Article 11(1) of Directive 2011/92 and in Article 9(3) of the Aarhus Convention. |

That view of the right to bring proceedings corresponds to that laid down in Article 11(1) of Directive 2011/92 and in Article 9(3) of the Aarhus Convention.

| 46 | That being so, it is apparent from recitals 24 and 37 and from first indent of Article 1 of Directive 2000/60 that that directive protects water not only as a component of the ecosystem, but also as a drinking water supply for the population. Therefore, according to the referring court, the view must be taken that the obligations laid down in that directive contribute to protecting human health. In accordance with the case-law of the Court (judgments of 25 July 2008, Janecek, C‐237/07, EU:C:2008:447; of 8 November 2016, Lesoochranárske zoskupenie VLK, C‐243/15,EU:C:2016:838; and of 20 December 2017, Protect Natur-, Arten- und Landschaftsschutz Umweltorganisation, C‐664/15, EU:C:2017:987), persons whose health is endangered by the infringement of mandatory provisions of a directive should be able to rely on those provisions before the competent national court. |

| 47 | In the light of those considerations, the referring court finds that it is conceivable that the claimants in the main proceedings who have a domestic well within the area covered by the project at issue may be able to plead an infringement of the prohibition of deterioration and of the obligation to enhance the status of bodies of water laid down in Directive 2000/60 in the case where their health may be endangered as a result of the failure to comply with those obligations. |

| 48 | In those circumstances, the Bundesverwaltungsgericht (Federal Administrative Court) decided to stay the proceedings and to refer the following questions to the Court for a preliminary ruling:

| 50 | It follows from the order for reference that the project at issue, namely the construction of a section of motorway, was subject to an environmental impact assessment prior to its approval. In particular, it was likely to have an impact on the status of bodies of surface water and groundwater located within the boundaries of the project, inter alia because of rainwater drainage. However, before the contested decision was adopted, no documentation relating to the effects of the project on the water and compliance with the obligations arising, in particular, from Article 4 of Directive 2000/60 was made available to the public. According to the referring court, the approval of the project at issue is, therefore, vitiated by a procedural defect. |

| 51 | It is also clear from the order for reference that, during the consent procedure relating to the project at issue, the bodies of water concerned were monitored, but that this was not documented.

| 52 | Moreover, the referring court notes that the project at issue complies with the obligation to prevent deterioration of the status of bodies of water, laid down in Article 4(1) of Directive 2000/60. In view of the minimal increase in chloride levels, which will remain below the applicable limit values, that project will probably not lead to a deterioration in water quality. Consequently, according to the referring court, it is clear that the procedural defect invoked by the claimants in the main proceedings had no impact on the tenor of the contested decision. |

The first question referred to the Court must be answered on the basis of the latter premiss.

| 54 | It should be recalled that, under Article 11(1) of Directive 2011/92, Member States are required to ensure that, in accordance with the relevant national legal system, members of the ‘public concerned’ either having a sufficient interest, or maintaining the impairment of a right, where administrative procedural law of a Member State requires this as a precondition, have access to a review procedure in respect of decisions, acts or omissions subject to the public participation provisions of that directive in order to challenge their substantive or procedural legality. |

| 55 | Thus, the admissibility of an action may be conditional either on the existence of ‘a sufficient interest in bringing the action’, or on an applicant alleging ‘the impairment of a right’, depending on which of those conditions is adopted in the national legislation (see, to that effect, judgment of 16 April 2015, Gruber, C‐570/13, EU:C:2015:231, paragraph 33). |

Article 11(3) of Directive 2011/92 provides that Member States are to determine what constitutes a sufficient interest or impairment of a right, consistently with the objective of giving the public concerned wide access to justice.

| 58 | The Court has also held that, in the case where a procedural defect has no consequences that could possibly affect the purport of the contested decision, it cannot be regarded as impairing the rights of the party relying on it (see, to that effect, judgment of 7 November 2013, Gemeinde Altrip and Others, C‐72/12, EU:C:2013:712, paragraph 49). |

| 59 | Thus, in view of the fact that Article 11 of Directive 2011/92 leaves the Member States significant discretion to determine what constitutes impairment of a right within the meaning of Article 11(1)(b) thereof, it is permissible for national law not to recognise such an impairment if it is established that it is conceivable, in view of the circumstances of the case, that the contested decision would not have been different without the procedural defect invoked (see, to that effect, judgment of 7 November 2013, Gemeinde Altrip and Others, C‐72/12, EU:C:2013:712, paragraphs 50 and 51). |

Thus, in view of the fact that Article 11 of Directive 2011/92 leaves the Member States significant discretion to determine what constitutes impairment of a right within the meaning of Article 11(1)(b) thereof, it is permissible for national law not to recognise such an impairment if it is established that it is conceivable, in view of the circumstances of the case, that the contested decision would not have been different without the procedural defect invoked (see, to that effect, judgment of 7 November 2013, Gemeinde Altrip and Others, C‐72/12, EU:C:2013:712, paragraphs 50 and 51).

| 60 | Therefore, national legislation which makes the admissibility of actions brought by individuals subject to the condition that they allege an impairment of a right and which, at the same time, allows individuals to invoke a procedural defect affecting the public’s participation in the decision-making process, even though that defect has had no impact on the tenor of the decision at issue, enables an action to be brought also in cases where this is not required under Article 11(1)(b) of Directive 2011/92. |

Therefore, national legislation which makes the admissibility of actions brought by individuals subject to the condition that they allege an impairment of a right and which, at the same time, allows individuals to invoke a procedural defect affecting the public’s participation in the decision-making process, even though that defect has had no impact on the tenor of the decision at issue, enables an action to be brought also in cases where this is not required under Article 11(1)(b) of Directive 2011/92.

| 61 | The national legislature is therefore entitled to make the admissibility of an action for annulment of the decision approving a project on the ground of a procedural defect, where that defect is not such as to alter the meaning of that decision, subject to the condition that it actually deprived the claimants of their right to participate in the decision-making process. |

The national legislature is therefore entitled to make the admissibility of an action for annulment of the decision approving a project on the ground of a procedural defect, where that defect is not such as to alter the meaning of that decision, subject to the condition that it actually deprived the claimants of their right to participate in the decision-making process.

| 62 | So far as is relevant, it should also be stated that, as is noted in the second indent of paragraph 90 of the present judgment, in the absence, in the file made available to the public, of the data that are necessary in order to assess the effects of a project on the water, the public is unable to participate effectively in the decision-making process. |

| 63 | In light of all of the foregoing considerations, the answer to the first question referred is that Article 11(1)(b) of Directive 2011/92 must be interpreted as permitting Member States to provide that, when a procedural defect vitiating the decision approving a project does not alter the meaning of that decision, an application for annulment of that decision is admissible only if the irregularity at issue has denied the claimant his or her right, guaranteed by Article 6 of that directive, to participate in the environmental decision-making process. |

The second question

The second question

| 64 | By its second question, the referring court seeks to ascertain whether Article 4(1)(a) of Directive 2000/60 must be interpreted as precluding a situation in which it is only after a project has been approved that the checks to establish whether the requirements laid down therein have been met are carried out. |

| 65 | As appropriate, the referring court also seeks to ascertain whether Article 6 of Directive 2011/92 must be interpreted as meaning that the information to be made available to the public during the procedure for approving a project must always include documents which contain an examination of that project in the light of the requirements laid down in Directive 2000/60. |

| 66 | With regard to the first part of the second question, it should be noted, as a preliminary point, that the referring court’s questions concern not only the requirements laid down in Article 4(1)(a) of Directive 2000/60, in respect of surface waters, but also those laid down in Article 4(1)(b) of that directive, in respect of groundwater. |

With regard to the first part of the second question, it should be noted, as a preliminary point, that the referring court’s questions concern not only the requirements laid down in Article 4(1)(a) of Directive 2000/60, in respect of surface waters, but also those laid down in Article 4(1)(b) of that directive, in respect of groundwater.

| 67 | According to point (a) of the first paragraph of Article 1 of Directive 2000/60, the purpose of that directive is to establish a framework for the protection of inland surface waters, transitional waters, coastal waters and groundwater which prevents further deterioration and protects and enhances the status of aquatic ecosystems and terrestrial ecosystems directly depending on the aquatic ecosystems. |

67

According to point (a) of the first paragraph of Article 1 of Directive 2000/60, the purpose of that directive is to establish a framework for the protection of inland surface waters, transitional waters, coastal waters and groundwater which prevents further deterioration and protects and enhances the status of aquatic ecosystems and terrestrial ecosystems directly depending on the aquatic ecosystems.

| 68 | In that regard, it should be recalled that Article 4(1)(a) of Directive 2000/60 imposes two distinct, albeit intrinsically linked, objectives. First, in accordance with Article 4(1)(a)(i), Member States are required to implement the necessary measures to prevent deterioration of the status of all bodies of surface water (obligation to prevent deterioration). Secondly, pursuant to Article 4(1)(a)(ii) and (iii), Member States are required to protect, enhance and restore all bodies of surface water with the aim of achieving ‘good status’ by the end of 2015 at the latest (obligation to enhance) (judgment of 1 July 2015, Bund für Umwelt und Naturschutz Deutschland, C‐461/13, EU:C:2015:433, paragraph 39). |

| 69 | Article 4(1)(b) of Directive 2000/60 imposes, in respect of groundwater, obligations which are largely identical to those laid down in respect of surface waters. First, in accordance with Article 4(1)(b)(i), Member States are required to implement the measures necessary to prevent deterioration of the status of all bodies of groundwater (obligation to prevent deterioration). Secondly, pursuant to Article 4(1)(b)(ii), Member States are required to protect, enhance and restore all bodies of groundwater with the aim of achieving ‘good status’ by the end of 2015 at the latest (obligation to enhance). |

Article 4(1)(b) of Directive 2000/60 imposes, in respect of groundwater, obligations which are largely identical to those laid down in respect of surface waters. First, in accordance with Article 4(1)(b)(i), Member States are required to implement the measures necessary to prevent deterioration of the status of all bodies of groundwater (obligation to prevent deterioration). Secondly, pursuant to Article 4(1)(b)(ii), Member States are required to protect, enhance and restore all bodies of groundwater with the aim of achieving ‘good status’ by the end of 2015 at the latest (obligation to enhance).

| 70 | Therefore, as the Advocate General noted in point 56 of his Opinion, the objectives of Directive 2000/60 for surface waters and for groundwater are similar. |

70

Therefore, as the Advocate General noted in point 56 of his Opinion, the objectives of Directive 2000/60 for surface waters and for groundwater are similar.

| 71 | In that regard, it should be recalled that the objective of Directive 2000/60 is to achieve, by coordinated action, ‘good status’ for all EU surface waters and groundwater by 2015. Both the obligation to enhance and the obligation to prevent deterioration of the status of bodies of water are designed to attain that qualitative objective (see, to that effect, judgment of 1 July 2015, Bund für Umwelt und Naturschutz Deutschland, C‐461/13, EU:C:2015:433, paragraphs 37, 38 and 41). |

| 72 | Moreover, it follows from the wording, scheme and purpose of Article 4 of Directive 2000/60 that, like the requirements laid down in Article 4(1)(a) in respect of surface waters, which, as the Court noted in the judgment of 1 July 2015, Bund für Umwelt und Naturschutz Deutschland (C‐461/13, EU:C:2015:433, paragraph 43), are binding in nature, those laid down in Article 4(1)(b) in respect of groundwater are also binding. |

| 73 | It follows that Article 4(1) of Directive 2000/60 does not simply set out, in programmatic terms, mere management-planning objectives, but has binding effects, once the ecological status of the body of water concerned has been determined, at each stage of the procedure prescribed by that directive. |

It follows that Article 4(1) of Directive 2000/60 does not simply set out, in programmatic terms, mere management-planning objectives, but has binding effects, once the ecological status of the body of water concerned has been determined, at each stage of the procedure prescribed by that directive.

| 74 | Article 4 of Directive 2000/60 not only contains more long-term planning requirements provided for by management plans and programmes of measures, but also concerns specific projects to which the prohibition of deterioration of the status of bodies of water also applies. A Member State is consequently required to refuse authorisation for a project where it is such as to result in deterioration of the status of the body of water concerned or to jeopardise the attainment of ‘good status’ for bodies of surface water or groundwater, subject to the derogations also provided for in Article 4 (see, to that effect, judgment of 1 July 2015, Bund für Umwelt und Naturschutz Deutschland, C‐461/13, EU:C:2015:433, paragraphs 47, 48 and 50). |

| 75 | More specifically, as the Court has held, when a project is liable to have adverse effects on water, consent may be given to it only if the conditions set out in Article 4(7)(a) to (d) of that directive are satisfied. Without prejudice to the possibility of judicial review, the national authorities which are competent to authorise a project are required to review whether those conditions are satisfied before the grant of such an authorisation (see, to that effect, judgment of 1 June 2017, Folk, C‐529/15, EU:C:2017:419, paragraphs 36 and 39). |

| 76 | It follows from the foregoing that, during the procedure for approval of a project, and therefore before the decision is taken, the competent authorities are required, under Article 4 of Directive 2000/60, to check whether that project may have adverse effects on water which would be contrary to the requirements to prevent deterioration and to improve the status of bodies of surface water and groundwater. That provision therefore precludes such a check from taking place only after that time. |

That provision therefore precludes such a check from taking place only after that time.

| 77 | With regard to the second part of the second question, concerning the information to be made available to the public before a project is approved, it should be recalled that Article 2(1) of Directive 2011/92 requires that projects likely to have significant effects on the environment, referred to in Article 4 of that directive, read in conjunction with Annexes I or II thereto, must be subject to an environmental impact assessment before consent is granted (judgment of 28 February 2018, Comune di Castelbellino, C‐117/17, EU:C:2018:129, paragraph 24). |

| 78 | The requirement for such an assessment to be carried out as a preliminary step is justified by the fact that it is necessary for the competent authority to take into account effects on the environment at the earliest possible stage in all the technical planning and decision-making processes, the objective being to prevent the creation of pollution or nuisances at source rather than subsequently trying to counteract their effects (judgment of 28 February 2018, Comune di Castelbellino, C‐117/17, EU:C:2018:129, paragraph 25). |

In accordance with Article 3(b) of that directive, it is necessary to identify, describe and assess, in an appropriate manner, the direct and indirect effects of a project on soil, water, air, climate and the landscape.

| 80 | The information that the developer must, in any event, provide to the decision-making authority includes, in accordance with Article 5(3)(b) and (c) of Directive 2011/92, a description of the measures envisaged in order to avoid, reduce and, if possible, remedy significant adverse effects and the data required to identify and assess the main effects which the project is likely to have on the environment. |

Therefore, in the light of Article 3(b) of Directive 2011/92 and in view of the mandatory nature of the check to be carried out pursuant to Directive 2000/60, recalled in paragraphs 74 to 76 of the present judgment, and in view of the importance which that directive attaches to the protection of waters, it must be held that the information referred to in Article 5(3)(b) and (c) of Directive 2011/92 must contain the data that are necessary in order to assess the effects of a project on the status of the bodies of water concerned in the light of the criteria and requirements laid down in, inter alia, Article 4(1) of Directive 2000/60.

| 82 | Moreover, it follows from Article 5(1) of Directive 2011/92 that Member States must adopt the necessary measures to ensure that the developer supplies in an appropriate form the information specified in Annex IV to that directive, inasmuch as that information is relevant in order to assess the effects of a given project, and within the limits of what may reasonably be required of a private operator. In accordance with paragraph 4 of that annex, that information includes a description of the direct, indirect, secondary, cumulative, short-, medium- and long-term, permanent and temporary, positive and negative effects of the project resulting from, inter alia, the use of natural resources and the emission of pollutants. |

All information gathered in that regard must, in accordance with Article 6(3) of Directive 2011/92, be made available to the public concerned within reasonable time frames.

| 84 | In the light of the foregoing considerations, it must be concluded that, under Directive 2011/92 and, in particular, Articles 3, 5 and 6 thereof, the information made available to the public for consultation purposes before a project is approved must include the data that are necessary in order to assess the effects of that project on water, in the light of the criteria and requirements laid down in, inter alia, Article 4(1) of Directive 2000/60. |

The third question

The third question

| 91 | By its third question, the referring court seeks to ascertain whether Article 4(1)(b)(i) of Directive 2000/60 must be interpreted as meaning that the exceedance of a parameter of at least one of the environmental quality standards must be regarded as a deterioration of the chemical status of a body of groundwater as a result of a project. It also wishes to ascertain whether a foreseeable increase in the concentration of a pollutant when the threshold set for that pollutant has already been exceeded must be regarded as constituting such a deterioration. |

It also wishes to ascertain whether a foreseeable increase in the concentration of a pollutant when the threshold set for that pollutant has already been exceeded must be regarded as constituting such a deterioration.

| 92 | It should be recalled that, in its judgment of 1 July 2015, Bund für Umwelt und Naturschutz Deutschland (C‐461/13, EU:C:2015:433, paragraph 70), the Court held that the concept of ‘deterioration of the status’ of a body of surface water, referred to in Article 4(1)(a)(i) of Directive 2000/60, must be interpreted as meaning that there is deterioration as soon as the status of at least one of the quality elements, referred to in Annex V to that directive, falls by one class, even if that fall does not result in a fall in classification of the body of water in question as a whole. However, if the quality element concerned is already in the lowest class, any deterioration of that element constitutes a ‘deterioration of the status’ of a body of surface water, within the meaning of that provision. |

| 93 | As the Advocate General noted in point 55 of his Opinion, it is true that, unlike bodies of surface water – for which Directive 2000/60 provides a scale of five ecological status classes – that directive distinguishes only between ‘good status’ and ‘poor status’ with regard to the quantitative and chemical status of bodies of groundwater. It follows from Article 2(25) and (28) of that directive that that classification is made using the tables in points 2.1.2 and 2.3.2 of Annex V thereto. |

| 94 | However, it should be noted that, despite those differences in the method for determining the status of bodies of water, depending on whether they are surface water or groundwater, the same principles determine the scope of the concept of ‘deterioration of the status’ of water, irrespective of the type of water concerned. |

| 95 | It has been stated in paragraphs 68 to 72 of the present judgment that the objectives of Directive 2000/60, in respect of both surface water and groundwater, and the obligations deriving from Article 4(1) of that directive for those types of water are largely identical. |

It has been stated in paragraphs 68 to 72 of the present judgment that the objectives of Directive 2000/60, in respect of both surface water and groundwater, and the obligations deriving from Article 4(1) of that directive for those types of water are largely identical.

| 96 | In particular, this is the case in respect of the obligation to prevent deterioration of the status of bodies of water, provided for in Article 4(1)(a)(i) of that directive in the case of surface water and in Article 4(1)(b)(i) in the case of groundwater. Those two provisions contain no reference to the classification laid down for those types of water in Annex V to that directive, and therefore the concept of ‘deterioration of the status’ of waters is a concept of general scope (see, to that effect, judgment of 1 July 2015, Bund für Umwelt und Naturschutz Deutschland, C‐461/13, EU:C:2015:433, paragraph 61). |

| 97 | Moreover, the Court has held that, although the classes provided for in Annex V to Directive 2000/60 were decisive for determining whether there is a deterioration, after a body of surface water has been classified in the lowest class, further deterioration of the status of that body of water would legally no longer be possible. However, given the very purpose of Directive 2000/60, bodies of water which have a poor status merit particular attention in the context of water management (see, to that effect, judgment of 1 July 2015, Bund für Umwelt und Naturschutz Deutschland, C‐461/13, EU:C:2015:433, paragraph 63). |

| 99 | In that context, account should also be taken of Article 4(5)(c) of Directive 2000/60, which expressly lays down a prohibition of all further deterioration as regards heavily modified bodies of surface water and groundwater for which Member States may aim to achieve less stringent environmental objectives (see, to that effect, judgment of 1 July 2015, Bund für Umwelt und Naturschutz Deutschland, C‐461/13, EU:C:2015:433, paragraph 64). |

| 100 | In the light of those factors, the concept of ‘deterioration of the status’ of bodies of water must be interpreted by reference to both a quality element and a substance. Thus, the obligation to prevent deterioration of the status of a body of water retains all its practical effect, on condition that it encompasses all changes liable to undermine achievement of the principal objective of Directive 2000/60 (see, to that effect, judgment of 1 July 2015, Bund für Umwelt und Naturschutz Deutschland, C‐461/13, EU:C:2015:433, paragraph 66). |

| 101 | Furthermore, as regards the criteria for concluding that there is a deterioration of the status of a body of water, it should be noted that it is clear from the scheme of Article 4 of Directive 2000/60, in particular Article 4(6) and (7), that a deterioration of the status of a body of water, even if transitory, is authorised only subject to strict conditions. It follows that the threshold beyond which breach of the obligation to prevent deterioration of the status of a body of water is found must be as low as possible (see, to that effect, judgment of 1 July 2015, Bund für Umwelt und Naturschutz Deutschland, C‐461/13, EU:C:2015:433, paragraph 67). |

| 102 | As regards, specifically, the examination of the chemical status of bodies of groundwater, it is clear from point 2.3.1 of Annex V to Directive 2000/60 that water conductivity and the concentration of pollutants are the relevant parameters. The table in point 2.3.2 of that annex sets out for each of those parameters the quality elements that must be taken into account in order to determine whether the chemical status of a body of water is ‘good’ or ‘poor’. |

| 103 | First, in respect of the concentration of pollutants, that examination is based on three quality elements. In the first place, the concentrations of pollutants do not exhibit the effects of saline or other intrusions. In the second place, those concentrations do not exceed the quality standards applicable under other relevant legislation in accordance with Article 17 of Directive 2000/60. In the third place, and lastly, the concentrations of pollutants in the groundwater do not prevent attainment of the environmental objectives specified under Article 4 of that directive for associated surface waters, nor do they result in any significant diminution of the ecological or chemical quality of such bodies or cause any significant damage to terrestrial ecosystems which depend directly on the groundwater body. |

Secondly, in respect of conductivity, the only requirement is that changes in conductivity are not indicative of saline or other intrusion into the groundwater body.

| 105 | In so far as point 2.3.2 of Annex V to Directive 2000/60 refers to quality standards applicable under other relevant legislation in accordance with Article 17 of that directive, it should be noted that Article 17 provides for the adoption, by the EU legislature, of specific measures to prevent and control groundwater pollution which include, inter alia, criteria for assessing good groundwater chemical status, in accordance with point 2.2 of Annex II and points 2.3.2 and 2.4.5 of Annex V to that directive. On that basis, the EU legislature adopted Directive 2006/118. |

In so far as point 2.3.2 of Annex V to Directive 2000/60 refers to quality standards applicable under other relevant legislation in accordance with Article 17 of that directive, it should be noted that Article 17 provides for the adoption, by the EU legislature, of specific measures to prevent and control groundwater pollution which include, inter alia, criteria for assessing good groundwater chemical status, in accordance with point 2.2 of Annex II and points 2.3.2 and 2.4.5 of Annex V to that directive. On that basis, the EU legislature adopted Directive 2006/118.

| 106 | Article 3(1) of Directive 2006/118 provides that, for the purposes of the assessment of the chemical status of a body of groundwater, Member States are required to use, first, the groundwater quality standards in the list in Annex I to that directive and, secondly, the threshold values to be established by Member States in accordance with Annex II to that directive, in particular for the pollutants which, within the territory of a Member State, have been identified as contributing to the characterisation of bodies of groundwater as being at risk. |

| 107 | Consequently, those quality standards and threshold values constitute a quality element for the purposes of point 2.3.2 of Annex V to Directive 2000/60 which makes it possible to assess one of the parameters for determining the classification of the status of a body of groundwater, namely the concentration of pollutants. |

Consequently, those quality standards and threshold values constitute a quality element for the purposes of point 2.3.2 of Annex V to Directive 2000/60 which makes it possible to assess one of the parameters for determining the classification of the status of a body of groundwater, namely the concentration of pollutants.

| 108 | Given that, as noted in paragraph 100 of the present judgment, the concept of ‘deterioration of the status’ of bodies of water must be interpreted by reference to a quality element or substance and, as is clear from paragraph 101 of the present judgment, the threshold beyond which breach of the obligation to prevent deterioration of the status of a body of water is found must be as low as possible, it must be held that the failure to observe one of the quality elements referred to in point 2.3.2 of Annex V to Directive 2000/60 constitutes a deterioration of the chemical status of the body of groundwater concerned. |

108

Given that, as noted in paragraph 100 of the present judgment, the concept of ‘deterioration of the status’ of bodies of water must be interpreted by reference to a quality element or substance and, as is clear from paragraph 101 of the present judgment, the threshold beyond which breach of the obligation to prevent deterioration of the status of a body of water is found must be as low as possible, it must be held that the failure to observe one of the quality elements referred to in point 2.3.2 of Annex V to Directive 2000/60 constitutes a deterioration of the chemical status of the body of groundwater concerned.

| 109 | In particular, the exceedance, in a body of groundwater, of a single one of the quality standards or threshold values, within the meaning of Article 3(1) of Directive 2006/118, must be classified as amounting to an infringement of the obligation to prevent the deterioration of the status of a body of groundwater. |

| 110 | Moreover, for the same reasons as those set out in paragraph 108 of the present judgment and in the light of, inter alia, the considerations noted in paragraph 97 thereof, any subsequent increase in the concentration of a pollutant that, with reference to Article 3(1) of Directive 2006/118, already exceeds an environmental quality standard or a threshold value set by the Member State also constitutes a deterioration. |

| 111 | Furthermore, in order to answer the referring court’s questions in respect of the consideration of changes in the concentration of pollutants found locally in order to determine whether there is a deterioration of the chemical status of a body of water, it should be noted that point 2.4 of Annex V to Directive 2000/60 establishes the main criteria for the monitoring of groundwater chemical status. Point 2.4.5 of that annex, which is expressly mentioned by the referring court, sets out requirements relating to interpretation and presentation. |

Point 2.4.5 of that annex, which is expressly mentioned by the referring court, sets out requirements relating to interpretation and presentation.

| 112 | Admittedly, although the latter provision stipulates that the classification of the chemical status of a body of groundwater as ‘good’ or ‘poor’ must be made by aggregating the results of the individual monitoring points within a body of water, this does not mean that, in order to find that there has been a deterioration of that status, the whole of the body of groundwater must be affected. |

| 113 | In particular, it is clear from the role and the importance of each monitoring site in the system for monitoring groundwater quality established by Directive 2000/60, in particular in point 2.4 of Annex V, that the failure to comply with one quality element at a single monitoring point is sufficient for a finding that there is a deterioration of the status of a body of groundwater for the purposes of Article 4(1) of that directive. |

| 114 | In accordance with point 2.4 of Annex V to that directive, the location of monitoring points must provide a coherent and comprehensive overview of groundwater chemical status within each river basin. To that end, that provision lays down various criteria in respect of the selection of monitoring sites which, as confirmed by Article 4(3) of Directive 2006/118, must provide representative monitoring data. |

To that end, that provision lays down various criteria in respect of the selection of monitoring sites which, as confirmed by Article 4(3) of Directive 2006/118, must provide representative monitoring data.

| 115 | Thus, the failure to comply with one quality element at a single monitoring point indicates the existence, for the purposes of Article 4(1)(b)(i) of Directive 2000/60, of a deterioration of the chemical status of at least a significant part of a body of groundwater. |

115

Thus, the failure to comply with one quality element at a single monitoring point indicates the existence, for the purposes of Article 4(1)(b)(i) of Directive 2000/60, of a deterioration of the chemical status of at least a significant part of a body of groundwater.

| 116 | Moreover, it is admittedly possible that, despite the exceedance of a groundwater quality standard or of a threshold value at one or more monitoring points, a body of groundwater may be regarded as being of good chemical status in accordance with Article 4(2)(c) of Directive 2006/118. However, in that event, under Article 4(5) of that directive, Member States are, in accordance with Article 11 of Directive 2000/60, required to 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 affected by that exceedance. |

117

The measures referred to in Article 11 of Directive 2000/60 include the establishment of programmes in order to achieve the objectives established under Article 4 of that directive.

| 118 | Therefore, where a quality element is not observed at a single monitoring point in a body of groundwater, it must be found that there is a deterioration of the chemical status of that body of water, for the purposes of Article 4(1)(b)(i) of Directive 2000/60. |

| 119 | In the light of all of the foregoing considerations, the answer to the third question referred is that Article 4(1)(b)(i) of Directive 2000/60 must be interpreted as meaning that, first, the exceedance of at least one of the quality standards or threshold values referred to in Article 3(1) of Directive 2006/118 and, secondly, a foreseeable increase in the concentration of a pollutant when the threshold set for that pollutant has already been exceeded must be regarded as a deterioration of the chemical status of a body of groundwater as a result of a project. The values measured at each monitoring point must be taken into account individually. |

The fourth question

The fourth question

| 120 | By its fourth question, the referring court seeks to establish, in essence, whether Article 4(1) of Directive 2000/60, read in the light of Article 19 TEU and Article 288 TFEU, must be interpreted as meaning that the members of the public concerned by a project must be able to assert, before the competent national courts, that there has been a breach of the requirements to prevent the deterioration of bodies of water and to improve the status of those bodies of water. |

120

By its fourth question, the referring court seeks to establish, in essence, whether Article 4(1) of Directive 2000/60, read in the light of Article 19 TEU and Article 288 TFEU, must be interpreted as meaning that the members of the public concerned by a project must be able to assert, before the competent national courts, that there has been a breach of the requirements to prevent the deterioration of bodies of water and to improve the status of those bodies of water.

| 121 | In that regard, it should be noted that, according to settled case-law of the Court, it would be incompatible with the binding effect conferred by Article 288 TFEU on a directive to exclude, in principle, the possibility that the obligations which it imposes may be relied on by the persons concerned (judgment of 3 October 2019, Wasserleitungsverband Nördliches Burgenland and Others, C‐197/18, EU:C:2019:824, paragraph 30 and the case-law cited). |

| 122 | In particular, where the EU legislature has, by directive, imposed on Member States the obligation to pursue a particular course of action, the effectiveness of such action would be weakened if individuals were prevented from relying on it before their national courts, and if the latter were prevented from taking it into consideration as an element of EU law in deciding whether the national legislature, in exercising the choice open to it as to the form and methods for implementation, has kept within the limits of its discretion set out therein (judgment of 3 October 2019, Wasserleitungsverband Nördliches Burgenland and Others, C‐197/18, EU:C:2019:824, paragraph 31 and the case-law cited). |

| 123 | The Court inferred from this that at least the natural or legal persons directly concerned by an infringement of provisions of an environmental directive must be in a position to require the competent authorities to observe such obligations, if necessary by pursuing their claims by judicial process (see, to that effect, judgment of 3 October 2019, Wasserleitungsverband Nördliches Burgenland and Others, C‐197/18, EU:C:2019:824, paragraph 32). |

| 124 | In that regard, the referring court states that, in the context of their action, some of the claimants in the main proceedings take the view that the project at issue is likely to result in the deterioration of the status of the body of groundwater which feeds their domestic wells from which they obtain drinking water. However, neither the information contained in the order for reference nor the observations submitted to the Court are capable of establishing the relevance, for the claimants in the main proceedings, of the bodies of surface water that may also be affected by the project at issue. In those circumstances, it does not appear that the claimants in the main proceedings can be concerned by a possible infringement of obligations deriving from Article 4(1)(a) of Directive 2000/60, with the result that the Court’s examination will concern only Article 4(1)(b), regarding groundwater. |

| 125 | In order to determine whether persons, such as the claimants in the main proceedings, are directly concerned by an infringement of the obligations provided for in Article 4(1)(b) of Directive 2000/60, account must be taken of the purpose of that directive and of the content of that provision, the proper application of which is sought before the referring court (see, to that effect, judgment of 3 October 2019, Wasserleitungsverband Nördliches Burgenland and Others, C‐197/18, EU:C:2019:824, paragraph 35). |

In order to determine whether persons, such as the claimants in the main proceedings, are directly concerned by an infringement of the obligations provided for in Article 4(1)(b) of Directive 2000/60, account must be taken of the purpose of that directive and of the content of that provision, the proper application of which is sought before the referring court (see, to that effect, judgment of 3 October 2019, Wasserleitungsverband Nördliches Burgenland and Others, C‐197/18, EU:C:2019:824, paragraph 35).

| 126 | In that regard, it is clear from paragraph 71 of the present judgment that the objective of Directive 2000/60 is to achieve, by coordinated action, ‘good status’ for all EU surface waters and groundwater by 2015. Both the obligation to enhance and the obligation to prevent deterioration of the status of bodies of water are designed to attain that qualitative objective. |

In that regard, it is clear from paragraph 71 of the present judgment that the objective of Directive 2000/60 is to achieve, by coordinated action, ‘good status’ for all EU surface waters and groundwater by 2015. Both the obligation to enhance and the obligation to prevent deterioration of the status of bodies of water are designed to attain that qualitative objective.

| 127 | As is clear from the first indent of the second paragraph of Article 1 of Directive 2000/60, that objective contributes, as regards groundwater specifically, to the provision of a sufficient supply of good quality surface water and groundwater as needed for sustainable, balanced and equitable water use. |
| --- | --- |

127

As is clear from the first indent of the second paragraph of Article 1 of Directive 2000/60, that objective contributes, as regards groundwater specifically, to the provision of a sufficient supply of good quality surface water and groundwater as needed for sustainable, balanced and equitable water use.

| 128 | Accordingly, it must be held that, by its objective and the obligations laid down in Article 4(1)(b) in order to attain that objective, Directive 2000/60 also pursues the specific objective of protecting groundwater as a resource for human use. |

128

Accordingly, it must be held that, by its objective and the obligations laid down in Article 4(1)(b) in order to attain that objective, Directive 2000/60 also pursues the specific objective of protecting groundwater as a resource for human use.

| 129 | That interpretation of the objectives of Directive 2000/60 is confirmed by point (d) of the first paragraph of Article 1 and by the second indent of the second paragraph of Article 1, read in conjunction with Article 2(33) of that directive. |
| --- | --- |

129

That interpretation of the objectives of Directive 2000/60 is confirmed by point (d) of the first paragraph of Article 1 and by the second indent of the second paragraph of Article 1, read in conjunction with Article 2(33) of that directive.

| 130 | It is clear from point (d) of the first paragraph and the second indent of the second paragraph of Article 1 that the regulatory framework established by that directive is intended to achieve a progressive and significant reduction of groundwater pollution and to prevent further pollution. In accordance with Article 2(33), water pollution arises from any introduction of substances into the water which may be harmful to human health or to the quality of aquatic ecosystems, in such a way that there is interference with the amenities of the environment and, more specifically, water or its legitimate use. |

It is clear from point (d) of the first paragraph and the second indent of the second paragraph of Article 1 that the regulatory framework established by that directive is intended to achieve a progressive and significant reduction of groundwater pollution and to prevent further pollution. In accordance with Article 2(33), water pollution arises from any introduction of substances into the water which may be harmful to human health or to the quality of aquatic ecosystems, in such a way that there is interference with the amenities of the environment and, more specifically, water or its legitimate use.

| 131 | It therefore follows from point (d) of the first paragraph and the second indent of the second paragraph of Article 1 of Directive 2000/60, read in conjunction with Article 2(33) thereof, that the purpose of reducing and preventing pollution is, inter alia, to allow the legitimate use of groundwater. |

It therefore follows from point (d) of the first paragraph and the second indent of the second paragraph of Article 1 of Directive 2000/60, read in conjunction with Article 2(33) thereof, that the purpose of reducing and preventing pollution is, inter alia, to allow the legitimate use of groundwater.

| 132 | A person who has the right to draw and use groundwater is using that groundwater legitimately. That person is, therefore, directly concerned by the infringement of the obligations to enhance and to prevent the deterioration of the status of bodies of groundwater that supply his or her source since that infringement is capable of interfering with its use (see, by analogy, judgment of 3 October 2019, Wasserleitungsverband Nördliches Burgenland and Others, C‐197/18, EU:C:2019:824, paragraphs 40 and 42). |

| 133 | In view of the variety of uses of groundwater referred to in the first indent of the second paragraph of Article 1 and in Article 2(33) of Directive 2000/60, the fact that the exceedance of just one of the quality standards or threshold values, within the meaning of Article 3(1) of Directive 2006/118, does not, as such, involve a danger to the health of the persons wishing to bring an action is not capable of calling that conclusion into question (see, by analogy, judgment of 3 October 2019, Wasserleitungsverband Nördliches Burgenland and Others, C‐197/18, EU:C:2019:824, paragraph 41). |

| 134 | Therefore, since the claimants in the main proceedings lawfully use the groundwater in question, they are directly concerned by the infringement of those obligations. |

Therefore, since the claimants in the main proceedings lawfully use the groundwater in question, they are directly concerned by the infringement of those obligations.

| 135 | In the light of all of the foregoing considerations, the answer to the fourth question referred is that point (b) of the first paragraph of Article 1 of Directive 2000/60 and the first indent of the second paragraph of Article 1 of that directive, together with Article 4(1)(b) thereof, read in the light of Article 19 TEU and Article 288 TFEU, must be interpreted as meaning that the members of the public concerned by a project must be able to assert, before the competent national courts, that there has been a breach of the requirements to prevent the deterioration of bodies of water and to improve the status of those bodies of water, if that breach concerns them directly. |
