  1. Tasks of Drafting Group III 1 Definition of point sources 2 How to derive restoration targets or quality standards? 3 What could be regulated in the Daughter Directive? 5 First estimation of costs and cost efficiency

  2. Emission limit values? Quality standards? Environmental quality standards for surface waters? Restoration target values? Point Source

  3. Definition of point sources Point source: An identifiable and localised area, structure or facility which can cause pollution of groundwater (e. g. contaminated sites) ! New landfills and technical installations should only be considered as point sources if they actually cause groundwater pollution

  4. Restoration target values A Europe-wide set of restoration target values for point sources (e. g. contaminated sites) is not appropriate: • Different geological and hydrogeological conditions • Individual pollution pattern for every point source • Technical feasibility • etc

  5. Quality standards • Pro quality standards • Comparability between Member States (according to surface waters quality standards) • Common standards for EU and common level of groundwater protection • Contra quality standards • Quality standards could become restoration target values • Natural concentrations could exceed quality standards • Importing standards from other directives does not fit for the purpose of groundwater protection

  6. Point source pollution of groundwater bodies Point source Groundwater body

  7. First estimation of costs (Million €) Reference: EEA 2000 Austria 1500 Belgium (Flan.) 6900 Denmark 480 Finland 900 France n. i. Germany n. i. - Bavaria 2500 Greece n. i. Ireland n. i. Italy 510 Luxembourg n. i. The Netherlands 23000 - 26000 Portugal n. i. Spain 800 Sweden 3532 United Kingdom 13000 - 39000

  8. Measurements • Tiered approach (subsidiarity) • Regional-local level • Assessment of points sources (vs groundwater) • Inventorisation of potential point sources • concept for prevention of contamination • assessment strategy for point sources (focus groundwater • and receptors

  9. Measurements (2) • Management concept for point sources • historical-new contamination • risk-based approach • BAT • don’t accept expanding plumes (within limited time frame)

  10. Measurements (3) • EU-level + reporting • Assessment of risks (vs GWB or sub-GWB) • define “risk-zones” (vulnerability, land-use, …) • implement monitoring (and reporting) system • assessment strategy for risk zones (focus groundwater • and receptors

  11. Measurements (4) • Management concept for risk zones • historical-new contamination • risk-based approach • BAT • don’t accept expanding plumes (within limited time frame)

  12. Parameters? A EU-wide parameter list of substances for EU-relevant monitoring is desirable, EU-wide values are not required values will come out of site-specific risk assessment
