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

! 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

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

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)

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

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

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