Case studies - General conclusions
 The DSS and its associated reports and tools have
been used in the five case studies which have very
different characteristics (size, compounds in focus,
administrative structure, availability of information)
 Experiences will form the basis of the SOCOPSE
Synthesis report

Case studies
General conclusions based on the results from the
different cases
 The DSS application fits well with the work with the river
basin management plan (RBMP) as required by the EUWFD
 Strong interaction with stakeholders (authorities) was
important in the DSS process and helped to better
understand the existing and future problems and to define
the main challenges for the catchment.

Case studies - General conclusions
 A general lack of information for present emissions has
been identified
Factsheets and Substance reports were useful for
identification of sources and emission control measures
 The lack of consistent data have implication on the
evaluation of the measures to reduce emissions
 Expert judgment and models can be used as complement
to assess the change of discharge loads from the sources

Case studies - General conclusions
 A lack of data on environmental concentrations, to be
used to assess the water quality for the selected priority
substances, was identified
-Monitoring is often carried out in campaigns and in
research projects
- If data is available there is often poor temporal and spatial
resolution
-A critical point is the data quality
-All data (e.g. from research community) is not available to
authorities

Case studies - General conclusions
 Modeling combined with available emission and
monitoring data can be used to check consistency (mass
balance) and identify missing sources and/or potential
sites where EQS are exceeded
Fugacity based models e.g. have successfully been used in
two of the case studies, Vantaa River and VAH

 A need was identified to use the DSS system for "new"
emerging substances
