Pilot investigation of mechanisms for a Watch List to support the identification of Priority Substances

EEA Workshop on Emerging Pollutants, Copenhagen, 5-6 Dec 2011 2

A vicious circle

EEA Workshop on Emerging Pollutants, Copenhagen, 5-6 Dec 2011 3

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

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

Structureof 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

Structureof 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

EEA Workshop on Emerging Pollutants, Copenhagen, 5-6 Dec 2011 10

Structureof 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.

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 (200-250

samples) Grant access to WFD Stations Provide screening information Favour link to research and innovation (
