ANNEX I GROUNDWATER QUALITY STANDARDS
1 For the purposes of assessing groundwater chemical status in accordance with Article 4, the following groundwater quality standards will be the quality standards referred to in Table 2.3.2 in Annex V to Directive 2000/60/EC and established in accordance with Article 17 of that Directive.
Pollutant | Quality standards | Comment |
|---|
Nitrates | 50 mg/l | For activities falling within the scope of Directive 91/676/EEC, programmes and measures required in relation to this value ( i.e. 50 mg/l) will be in accordance with that Directive 1. |
Active substances in pesticides, including their relevant metabolites, degradation and reaction products 2 | 0,1 µg/l 0,5 µg/l (total) 3 | |
1 Activities outside the scope of Directive 91/676/EEC are not covered by this provision.
2 "Pesticides" means plant protection products and biocidal products as defined in Article 2 of Directive 91/414/EEC and in Article 2 of Directive 98/8/EC, respectively.
3 "Total" means the sum of all individual pesticides detected and quantified in the monitoring procedure.
2 The results of the application of the quality standards for pesticides in the manner specified for the purposes of this Directive will be without prejudice to the results of the risk assessment procedures required by Directive 91/414/EEC or Directive 98/8/EC.
3 Where, for a given body of groundwater, it is considered that the groundwater quality standards could result in failure to achieve the environmental objectives specified in Article 4 of Directive 2000/60/EC for associated bodies of surface water, or in any significant diminution of the ecological or chemical quality of such bodies, or in any significant damage to terrestrial ecosystems which depend directly on the body of groundwater, more stringent threshold values will be established in accordance with Article 3 and Annex II to this Directive. Programmes and measures required in relation to such a threshold value will also apply to activities falling within the scope of Directive 91/676/EEC.
