1 Management of new and historical pollution sources
A view from the Common Forum on Contaminated Land

2 ! Definition of point sources Point source:
identifiable and localised area, space, structure or facility, emitting (or discharging) substances that can cause pollution of groundwater (e. g. contaminated sites) ! New installations which can cause groundwater pollution have to be monitored

3 Point Source: threats? Emission Locally high conc’s Spreading plumes
Landesumweltamt Point Source: threats? Emission Spreading plumes Risks for receptors Locally high conc’s WRRL aus Richtlinienentwurf zur ökologischen Gewässerqualität hervorgegangen. Erster Entwurf im Jahr 1997 vorgelegt Beschluss im Rat am , nur Dänemark enthielt sich der Stimme Obwohl gerade erst in Kraft getreten, befasst sich die LAWA schon seit einiger Zeit in zahlreichen Arbeitsgruppen intensiv mit der Thematik.

4 Point source pollution - Risk management zones
Groundwater body group of point sources, which together yield a significant flux of a substance that affect groundwater quality within a specific area or may affect receptors such as groundwater uses and aquatic or terrestrial ecosystems, and which require specific management requirements

5 Tiered approach (subsidiarity) Regional-local level:
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 (focus groundwater, receptors)

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

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

8 Measurements (4) Management concept for risk zones
historicalcontamination risk-based approach BAT don’t accept expanding plumes (within limited time frame)

9 Prevent spreading plumes
