1. Table of existing standard methods and proposed quality standards for priority substances in water
AMPS (2)
Jan Wollgast

2. Legal Background 2000/60/EC Water Framework Directive (Dec.2000)
The Water Framework Directive requires the monitoring of water quality elements to be performed by methods which are conform to CEN/ISO Standards or National/International Standards which ensure the provision of data of an equivalent scientific quality and comparability (Annex V, WFD).
2455/2001/EC List of priority substances Annex X. (Nov.2001)

3. AIM
To insure that analytical results used for compliance checking are comparable for all over Europe

4. Objectives
“Task is to provide a comprehensive table, which compiles information on CEN/ISO methods including performance criteria and other information necessary in policy support “ (AMPS 1)
One page
Basis for:
identification/discussion of needs for development
advice to EAF on PS

5. Contributions D, CEN first version of the table
Comments/Discussion within drafting group
Comments from AMPS WG members
Addition of proposed Quality Standards (Fraunhofer report) & 76/464/EEC “dangerous compounds”
Current version includes comments/suggestions

7. Priority Substance 2455/2001/EC List of priority substances
Proposed QS for single PBDEs & PAHs, (Fraunhofer Report)
76/464/EEC and “daughter” directives

9. EN
ISO
National Standards
US EPA
(Draft status)

11. Range of Application
" The range of application corresponds to the lowest and highest concentrations for which tests of precision and bias have been carried out using the system without modification...“
(ISO/TR 13530, )

12. Matrix
Drinking
Ground
Surface
Waste
WATER
Sludge
Sediment
Soil

14. Method Performance
Conc. = concentrations of the analyte(s) in the intercomparison samples used for the determination of repeatability and reproducibility
SR = the relative reproducibility standard deviation

15. Method Performance
Do method performance criteria have to be proven, if a method should be proposed for monitoring under WFD requirements ?
Can we identify an acceptable SR?
(20 to 25%?)

17. Surface water specific method performance
Is a method performance tested in drinking water sufficient for application of the method in surface water?
Comments (AMPS members):
“Generally no, however, experience says that there are almost no difference in method performance between [D] and [S]”

19. Applicability in routine laboratories
Input from 4 countries (yes/no or remarks)
Standard methods being applied in a modified form were calculated as “yes”

21. Proposed QS AA-QS: MAC-QS:
 Annual average concentration
MAC-QS:
 Maximum admissible concentration (short term concentration peaks)
AA-QS for Inland (In) & Transitional (Tr) waters
AA-QS for Coastal (Co) & Territorial (Te) waters
(Peter Lepper, Fraunhofer IME, 2002)

22. IF
the quality standards proposed had been accepted without modification
then
would the available standard methods be sensitive enough to quantify accurately at this level?

23. C10-13 chloroalkanes

27. C10-13 chloroalkanes

28. Alachlor
Anthracene
Brominated diphenylethers
Cadmium and its compounds
C10-13 chloroalkanes
Chlorfenvinphos
Chlorpyrifos (-ethyl, -methyl)

30. 76/464/EEC and “daughter” directives
Still in force!
Quality objective for “dangerous compounds”
Red  particular relevant as no or higher QS proposed

32. Approximate average costs
Input only from 2 countries
Cost for individual compounds versus cost by “parameter groups”
Listing of service costs for chemical analysis (“Leistungsverzeichnis fuer chemische Arbeiten” ,VCH, 1992)

33. Approximate average costs
Cost for metal compounds are comparable (30-40E)
Costs for other Priority Substances vary (20-300E)
Sampling costs not included
 More input required

34. Additional comments (AMPS)
Sampling to be considered – EN/ISO methods?
Sample preparation – e.g., ISO and –2 and EN for preparation of samples for metal analysis in water, sediments or SPM
Identification of data quality objectives
Acceptance of alternative methods if validated and proved to be comparable
QA/QC on European level
