    1. Klodnica case study

    2. DSS

    3. Step 0 System Definition What are the geographical boundaries? river basin district Types of waters (inland, groundwater) Who has to decide, with whom? Who are involved in the decision making now and in the future. On what do they have to decide? And how? Institutional settings: Regional Water Management Board Stakeholders board Stakeholders? Stakeholders represent the land and water users as a part of the function of the river basin: industry, transport/navigation, recreation, living ecosystem, landscape elements. Represented by local authorities, sector organisations, industry organisations

    4. Water regions in Poland

    5. Klodnica in the Odra river basin

    6. River characteristics According to physical - geographical classification in Poland Klodnica Basin is located in upland area of Katowice (central part of macroregion Silesian Upland) and Raciborska Valley (south-eastern part of macroregion Silesian Lowland). From an administrative point of view is located in Silesia and Opole voivodships. The length of the Klodnica is 84 km and the basin area is 1125,80 km2. The river-head are located in south part of Katowice City on the land Murckowski Forest on 305 meters over sea level. The estuary is located in Kedzierzyn Kozle on 164 meters over sea level.

    7. Klodnica catchment: urban development

    8. Stakeholders In the Klodnica Basin the stakeholders group include: Regional Water Management Board Gliwice, Silesian provincial governor, Offices of all communities placed on Klodnica Basin (11 counties), Public bodies responsible for national monitoring and the control of the environment (Regional Inspectorate of the Environmental Protection in Katowice, Institute of Meteorology and Water Management and Centre of Examinations and the Control of the Environment), Gliwicki canal administration, Municipal units of public utilities, Industrial plants, Research institutes and research - developmental individuals, Ecological organization, General public, Agricultural sector.

    9. Step 1 Problem definition scheme

    10. Monitoring system organisation In Poland the State Environmental Monitoring on the base of the Environmental Law is coordinated by the State Environmental Inspectorate bodies: ؠ national network and regional networks by the Glwnego Inspektora Ochrony Srodowiska; ؠ local networks by the Wojewdzkiego Inspektora Ochrony Srodowiska in coordination with Glwny Inspektor Ochrony Srodowiska.

    11. Monitoring system changes Data for the years up to 2004 of uncertain quality for Cd and Hg 2004-2007 improved analitical techniques 2008 established protocols for priority substances monitoring in the State Environmenatl Monitoring System in Poland

    12. Monitoring characteristics Up to 2007 5 monitoring points in the area of Katowice aglomeration From 2007 in the monitoring network of surface waters in the Klodnica river catchment measurements of Hg are stopped except for one point Up to 2007 the analyses were performed 4 times in a year. Measurements of cadmium in all monitoring points are performed 4 times in a year In 2007 PIOS resigned from some monitoring points (point Klodnica 47,2 km).

    13. Klodnica river water quality

    14. Klodnica water quality screening

    15. Klodnica river water quality screening B(a)p - Benzo(a)pyrene B(b)f + B(k)f - benzo(b)fluoranthene + benzo(k)fluoranthene B(ghi)p + I(1,2,3-cd)p benzo(g,h,i)perylene + indeno(1,2,3-cd)pyrene * - 0.15 for class 4, 0.25 for class 5

    16. Water quality: Mercury EQS AA 0,05g/l

    17. Water quality: cadmium EQS 0,15 (Cl.4) 0,25 (Cl.5) EQS [g/l] Cl. 4 0,15 (dla CaCO3 100-200 mg/l) Cl. 5 0,25 (dla CaCO3 > 200 mg/l)

    18. WWA monitoring The WWA measured parameter: sum of six substances: (benzo(b)fluoranthene; benzo(a)pirene; dibenzo(a,h)antracene; benzo(g,h,i)perylene; indeno(1,2,3-cd)pirene). From 2006 (with exception of one point Bytomka 2,5 km) the WWA are not monitored in Klodnica catchment

    19. Step 2 making an inventory of possible sources, per substance and per location

    20. Key questions What are the main emissions sources affecting concentrations of PSs in aquatic ecosystems ? What are the emissions amounts of PSs from these sources? What are the major pathways of PSs in from their production/ generation until release to the atmosphere? What are the direct and indirect (through atmosphere and terrestrial ecosystems) contributions of PS releases to the aquatic ecosystems?

    21. Conceptual model

    22. Potential Sources of Hg, Cd, PAH emissions to water

    23. MFA

    24. The water treatment plants

    25. Air deposition Spatial distribution of mercury anthropogenic emissions in Europe in 2000 within the EMEP grid of 50 km by 50 km

    26. Wastewater discharges and treatment plants

    27. Landfills and industrial sites

    28. Step 3 inventory of autonomous trends that influence concentrations. This delivers the baseline scenario

    29. Key issues A key issue in answering the previous question is the definition of autonomous development, which can be considered as development which is beyond our control. This can include diverse things, such as: Changes in industry (new plants under construction, others closing down) Economic development (increase in consumption or production output) Human population increase or decrease in the catchment area Development in agriculture, technology, legislation, etc. Environmental change (i.e. rainfall, flooding, temperature, eutrophication)

    30. Sub - steps What are the sub-steps? IDENTIFY the drivers of change CREATE scenarios of emission levels and environmental change CHOOSE the time scale for simulation and SIMULATE future PS concentrations with environmental fate models ASSESS the uncertainty of simulation results IDENTIFY future problem locations (if any

    31. Step 4 What are possible measures? Process-oriented options End-of-pipe techniques Substitution of product (phase out) Options for other (diffuse) sources (Community level options)

    32. Four main criteria are proposed, with additional sub-criteria: Technical feasibility (applicability) Environmental impact (sustainability) Costs State of the art

    34. Costs the decision will only be based on the Cost of Compliance : the option with the lowest CoC will be chosen the decision will only be based on the risk reduction (% reduction of the pollutant): the option with the lowest risk will be chosen the option with the highest risk reduction (% reduction of concentration) per Euro spent will be chosen: CEA is applicable it has been determined that there are other relevant effects besides the costs of compliance and the reduction of the pollutant that have to be taken into account when selecting the most attractive options: SCBA or MCA may be relevant selection tools (see the previous section for a brief description)
