10. MS monitoring data will be collected via the End User Tool
Data collection: monitoring data
WISE
MS monitoring data will be collected via the End User Tool
The COM will consider all data submitted from now to 25 May 2007
Feedback expected until 16 March 2007

11. Different data sources:
Data collection: other data
Targeted data collection for chemical/physical properties, ecotox, etc.
From mid 2007 to end of 2007?
Different data sources:
Completed risk assessments (Tier 1 assessment) under Reg. (EEC) 793/93, Dir. 91/414/EEC, Dir. 98/8/EC (WFD Art. 16(2)a)
Targeted risk assessments (Tier 2 assessment) focusing on aquatic ecotoxicity and on human toxicity via the aquatic environment (ongoing RA, RA under Dir. 93/67/EEC, VRA) (WFD Art. 16(2)b,1st §)
Simplified risk assessments (Tier 3 assessment). (WFD Art. 16(2)b,2nd §) Scientific litterature, databases, etc.

13. Data processing Choose relevant metadata
(see document for data collection)
Discard data of demonstrated low quality: simplified quality check
see revised background document
Discard data of low plausibility (statistical outliers)
according to COMMPS
Aggregate data
1 data per substance × parameter
according to COMMPS
