1 CIS WFD SCG Meeting on 8/9 November Brussels EEA Workshop on Emerging Pollutants, Copenhagen, 5-6 Dec B. M. Gawlik Pilot investigation of mechanisms for a Watch List to support the identification of Priority Substances

2 EEA Workshop on Emerging Pollutants, Copenhagen, 5-6 Dec A vicious circle

3 EEA Workshop on Emerging Pollutants, Copenhagen, 5-6 Dec Background Monitoring of new PS and EQS critical Weak databases impose high safety factors Lack of data for not regulated substances Coordinated and integrated approach building on the existing infrastructure Facilitate QA/QC Idea for a Watch List mechanism ➡ Assessment by JRC ➡ Identify new candidate priority substances ➡ Establish a pan-European levels for occurrence and levels ➡ Representative sub-set of WFD Monitoring Stations (ca. 250) ➡ Suitable analytical protocols as a first guidance

4 EEA Workshop on Emerging Pollutants, Copenhagen, 5-6 Dec Can we have an impact? Data Quality Study (ENV, 2010) 2000 to 2008 (spring) data 1151 substances stations individual samplings analyses Water types 96% River Water 2% Transitional Water 1% Lake Water 1% Coastal Water Matrices covered 93% whole water 6.3% sediment 0.7% biota Benzene Total measurements:26737 LOQ missing:9.7% LOQ not compliant:2.6% Useful data:87.8% Cadmium and its compounds Total measurements: LOQ missing:40.3% LOQ not compliant:58.7% Useful data:1% (1039) Pentabrominated diphenyl ethers Total measurements:536 LOQ missing:1.5% LOQ not compliant:98.5% Useful data:0% 4 A closer look:

5 EEA Workshop on Emerging Pollutants, Copenhagen, 5-6 Dec Pan-European Screening by JRC Objective: To produce evidence-based and independent data on the occurrence and fate of less- investigated and new chemical substances in the environmental media on a manageable sample set. Characteristics: Concern-driven approach Integrative assessment Synchronisation and coordination of existing capacities Pan-regional assessments Non-probabilistic approach Multi-methods and –parameter Work plan (2008 – 2012) Surface Water Groundwater Effluents and sewage sludge Compost and biowaste Coastal waters The Lipid Project Soils Effect-based tools Substance/Property classes Pesticides (Candidate) priority substances Pharmaceuticals Personal care products Heavy Metals Industrial chemicals Effects of mixtures …

6 EEA Workshop on Emerging Pollutants, Copenhagen, 5-6 Dec Structure of the Pilot Exercise Identify possible short-comings Substance set should reflect different properties in terms of stability of the analyte in water required instrumentation (ICP, GC, LC) various degrees of polarity (ionic, polar to apolar) different release pathways (point release vs. diffuse emissions, different economic sectors). Consider available screening information JRC ensures the collection of existing screening information from the Member States Matrix approach: Proposal welcome Some 20 test substances (not to be mixed up with future Watch List Substances) Synchronisation with ongoing activities Identification of substances for the pilot study A sound Watch List Mechanism has to be science-based and needs to aim on those (emerging) pollutants identified of being of concern Testing the Feasibility

7 EEA Workshop on Emerging Pollutants, Copenhagen, 5-6 Dec Number of substances: 4 x 5 x 3 = 60 substances Polarity Economic sector Persistence Apolar Moderately polar Polar Ionic Household Industry Agriculture Energy Transport Persistent Moderate stability Instability Ideal...

8 EEA Workshop on Emerging Pollutants, Copenhagen, 5-6 Dec Number of substances: 3 x 3 x 2 = 18 substances Polarity Release Persistence Apolar Polar Ionic Point sources (not air) Runoff and related diffuse emissions Atmosphere and others Persistent Not persistent Feasible...

9 EEA Workshop on Emerging Pollutants, Copenhagen, 5-6 Dec Structure of the Pilot Exercise Use existing monitoring station network 5-10 sites per MS – in total 200 to 250 sites Official WFD Monitoring Sites only MS must agree to provide and share all relevant information (coordinates) Synchronisation with normal operation Methodology for site selection of the sites to be agreed a priori among the MS  Pragmatism Capture a “snap-shot” Experience shows that biases are averaged out on EU level Avoid extreme conditions of pollutions Consider rivers, lakes and coastal/transitional waters Selection of EU watch list sites The set of stations should represent typical scenarios in order to grasp the European picture. Testing the Feasibility

10 EEA Workshop on Emerging Pollutants, Copenhagen, 5-6 Dec Structure of the Pilot Exercise Selected expert laboratories vs. national laboratories Identify and nominate “expert laboratories” Stability of the compound in water samples is an important technical detail JRC is offering to take over ca. 50 % of the analytical work (capabilities and capacities provided) Deliver fully validated methods (uncertainty budget, Joint NORMAN/CEN protocol) Pre-normative input to the standardisation process. Performance indicators in compliance with the QA/QC Directive. Hand over final report to WG E Laboratories and analytical methods Transparency on the analytical methodology is generally accepted as a key criterion for an expert laboratory. Testing the Feasibility

11 EEA Workshop on Emerging Pollutants, Copenhagen, 5-6 Dec Planning and Timing Phase I Preparatory Nov-Dec 2011 Criteria Site selection Screening data CMEP approval Phase II Scene setting Jan-Mar 2012 Site selection (contacts) Expert labs Logistics prep. Sync campaign s Phase III Sampling Apr-Jun 2012 Dispatch to sites SamplingShipment Phase IV Analyses Mar-Jul 2012 Validated methods Sample pre- treatment Process samples Analytical report Phase V Reporting Sep-Oct 2012 Compile all findings Draft to CMEP Submit to WG E

12 EEA Workshop on Emerging Pollutants, Copenhagen, 5-6 Dec Resources Official WFD Monitoring JRC Screening Exercises Local and national exploration of Non-PS Commission funding (allocated for 50% plus logistics) Member States funding (already in place) Exploratory and research (in place)

13 EEA Workshop on Emerging Pollutants, Copenhagen, 5-6 Dec Breaking the vicious circle Substance is monitored Information on fate is accessible Prioritisation is possible EQS can be derived Legislation becomes feasible  Invite your laboratories to sync efforts  Delegate measurement capacity ( samples)  Grant access to WFD Stations  Provide screening information  Favour link to research and innovation (  EIP Water Efficiency)
