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

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
Measurements (2) • Management concept for point sources • historical-new contamination • risk-based approach • BAT • don’t accept expanding plumes (within limited time frame)
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
Measurements (4) • Management concept for risk zones • historical-new contamination • risk-based approach • BAT • don’t accept expanding plumes (within limited time frame)
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
