1 COMPARABILITY OF WATER STATUS ASSESSMENT Przemysław Gruszecki Mateusz Zakrzewski Chief Inspectorate for Environmental Protection, Poland Budapest, 2011 The Śniardwy Lake

2 JARFT ŚWIEśA PREGOŁA UCKER NIEMEN ODRA VISTULA ELBE River basin districts in Poland DANUBE DNIESTER

3 Polish water bodies and their typology (2010) Water bodies rivers lakes coastal transitional Types of water bodies Danube RB 11 Vistula RB ŚwieŜa RB 4 1 Jarft RB 6 Elbe RB 8 Odra RB Pregola RB Niemen RB Dniester RB 3 All river basins in Poland

4 Typology of water bodies in Poland JARFT ŚWIEśA PREGOŁA NIEMEN UCKER ELBE DNIESTER DANUBE

5 Sampling Points Categories of water bodies Type of monitoring rivers lakes reservoirs transitional coastal surveillance operational

6 Monitoring vs assessment comparability Not eachwb hasto be monitored(but methodsfor extrapolation are not fully developed) SM and its representativity Overall assessment and reports: SM, OM, both? The Hel Pennisula

7 Chemical status: Priority chemical substances, Other polluting substances STATUS OF WATER BODY WIOŚ laboratory Ecological status / potential: biological indicators, hydromorphology, physico chemical indicators Phytobenthos sample

8 Reference values and EQRs in PL Methods of ecological status assessment rivers lakes transitional coastal phytoplankton (chlorophyll a ) phytobenthos macroinvertebrates macroalgae and angiosperms macrophytes ichtiofauna Orange frame: intercalibrated Green field: assessment method and EQR Yellow field: method under development White field: not exist

9 Biological assessment

10 Biological assessment Comparability problems: One out all out rule is not in use in all EU Member States Gaps in intercalibration results (not all biological elements,, not all river/ lakes types) Intercalibrated assessment methods; sampling methods still differ Intercalibration only for natural WB Non-EU countries Limnephilidae sp.

11 Physico-chemical indicators Groups of physico-chemical chemicalindicators: Physical indicators Oxygen and organic pollutants indicators Salinity indicators Acidity indicators Nutrients concentration The Vistula River in Warsaw

12 Physico-chemical assessment Assessment rule: number of samples percentile number of samples < 12 maximum Exception for oxygen concentration: number of samples percentile number of samples < 12 minimum ONE OUT ALL OUT The Dunajec River

13 Physico-chemical assessment Comparability problems: One out all out? Methods for integration of results may differ between countries Boundariesmaybe ormaybe not type-specific Physico-chemical boundaries are not included in the IC process HMWB / AWB Non-EU countriesdo not haveto followtherdw assessment procedure The Vistula River

14 Hydromorphology Regular monitoring of river flow HM parametres as a part of HMWB / AWB designation HM parametres as a part of basin characteristics HM as a part of assessment mentioned only in a CIS guidance HM is an important element of all biological metrics The Biebrza River

15 Pressure related biological indicators Eutrophicatio n Land use Hydromorphology Diversity of microhabitat s Total degradation phytobenthic or phytoplanctonic algae hydromacrophytes ichtiofauna benthic macroinvertebrates

16 Operational monitoring Comparability problems: The same pressure different biological elements chosen Really comaparable results? Nenufars and Typha river plant community

17 Chemical status assessment List of substances given in EQS Directive [2008/150/EC] Standards for substances given in EQS Directive [2008/150/EC] Technical specifications for chemical analysis in QA/QC Directive[2009/90/EC] ONE OUT ALL OUT The Vistula River in Warsaw

18 Assessment of water bodies with many sampling points RiverWB (both natural and HM) results from closing points or all data assessment(average of metrics from all sampling points) Reservoirs Lakes WB (both natural and HM) all data assessment(average of metrics from all sampling points) Coastal WB Transitional WB

19 Multi-points WB assessment Comparability problems: Averageoffinalassessment? (indicatorlevel, groups of indicators, other?) One-bag rule? The Mazurian Lakes The Biebrza River

20 Comparability problems One-year assessment does give a real picture ofwb status OM doesnot givea realpictureofwb status One out all out rule Natural WB vshmwb / AWB Many monitoring points on one WB Non-EU countries are not WFD-obliged The Jeziorak Lake

21 Comparability-conclusions Common reports common indicators(eea Core- Set?) Common reports common data package(the same parametres, the same units) Multi-year assessment(data from the whole 6- year management period?) The Vistula River
