Task 3 – Scope of SOER parametersTask 3 – Scope of SOER parameters

Two sections discussed at March meeting• The selection of monitoring stations to

obtain representative information for SOER types of EEA SOE assessments

• Reporting sheets for SOEComments received from AT, FI, HU, NL, SE, SK, UK, and JRC/IESExtensive review within EEA and ETC/WTR

Comments: selection of monitoring Comments: selection of monitoring stations - assessmentsstations - assessments

• EEA activities strongly supported particularly in relation to improving the comparability and reliability of underlying SOER-data and presented results

• Relation between assessment of state and compliance reporting – discussed in Task 1

• Role of water accounts, e.g. in economic analysis? – yes, this is one of its potential applications

• Guidance document should talk about the use of data – believe it does, indicators etc.

7

Comments: selection of monitoring Comments: selection of monitoring stations - Monitoring networks stations - Monitoring networks

• Determinands for operational monitoring will differ from place to place and only monitored whilst water body is “at risk”. Operational monitoring stations less suitable for SOE assessments – discussed in revised document

• Some determinands updated annually, many determinands not updated annually. Thus will not have a “new representative” picture on a yearly basis and a representative picture for the population as a whole may not be reached until a certain time period has past (in some cases 6 years) – this is recognised by EEA

Comments: selection of monitoring stations - Comments: selection of monitoring stations - Presentation of assessments Presentation of assessments

• Scale of reporting of data may depend on the type of determinand: for physicochemical data, station would be the best level, for biological information, water body may be more appropriate – agreed, in reporting sheets

• Stations should be used for the SOE reporting. To use “water body” instead will probably make comparisons difficult depending on differences in how the WFD-directive is implemented in different countries - agreed

• Lowest level of SoE assessments should be river basins per country, non-monitored water bodies are in that way not relevant – agreed but assessment will need to take account of all water bodies

• Figure 1: It would be preferable to use the terminology of the WFD: sub-basin, river basin and river basin district – Lookout box added to text

9

Comments: Options for the selection of Comments: Options for the selection of monitoring stations monitoring stations

• Option 1 favoured option by 5 (AT, FI, SE, NL, SK) out of 7 (making comments) most realistic, practical and cost-effective – text revised accordingly

• Questions about purpose and practicability of some types of station: reference stations; targeted pressure stations for thematic reports; flux stations would confuse harmonisation initiatives and reporting from the various regional commissions – station types revised

• Option 3 may lead to problems with interpretation of results because of differences in monitoring networks, amount of follow up quality assurance questions would be endless – option 3 not being developed

Comments: Reporting sheetsComments: Reporting sheets• Xml schemas should make reporting easier – Task 4• Avoid duplication reporting of information such as that reported

for Articles 3, 5, 8 – yes, believe we have• Repetition should be taken out and made easier to understand -

tried to remove repetition in revised sheets e.g. GEO_INF• Will WFD SOE reporting for water quality entirely replace

EIONET? – they will be the same• What will the data entry process be like? – Task 4/5• Not many reporting sheets developed for marine SOE reporting -

should be further developed (with assessments and indicators) in cooperation with the marine conventions – agreed, now sheets for transitional and coastal waters, marine within EMMA

• Should be one common data flow serving the needs of both the marine conventions and EEA – to be discussed in EMMA, part of WISE

Comments: Reporting sheetsComments: Reporting sheetsNUT_ORG_SW NUT_ORG_SW

• Underline the most important determinands - done• Annual average concentrations of nutrients in transitional and

coastal waters would not be interpretable – winter means used in indicators

• A lot of the determinands asked for are not subsequently used in indicators – may be used for other assessments, commonest determinands used for indicators

• Unique site code/Unique station code ─ both were used – text revised• Is the CEN/ISO code sufficient information about the analytical

method? One standard may contain many alternatives – no it isn't, new request for information added

• Limit of detection and determination depends on laboratory and sampling series analysed: information not linked for each result in national database – text revised

• Depth interval for lakes should be defined when calculating annual or seasonal average concentrations – text revised.

Comments: Reporting sheetsComments: Reporting sheetsSTA_CHA_PRE STA_CHA_PRE

• Some of the characteristics may not be available for each lake in Finland- countries only expected to report what is available

• Mixing characteristics should be included for lakes though may not be directly available from data bases – will be added

• Proxy pressure information on the catchment upstream is not relevant for most of the marine monitoring stations and should be omitted - agreed

13

Comments: Reporting sheetsComments: Reporting sheetsNUT_GWNUT_GW

• What does 'Classification of samples taken’ mean? – explanation added

• Need to harmonise 'Statistical information accompanying disaggregated data' between sheets - done

• Statistical data associated with annual aggregates will not be possible for some sampling points because there will only be 1 sample/year - acknowledged

• Should selected water bodies be based on the given criteria, or all water bodies? – criteria given in revised paper

14

Comments: Reporting sheetsComments: Reporting sheetsHAZ_SW_BTA HAZ_SW_BTA

• For fish the concentration of the determinand should be for both wet weight and lipid weight – text revised

• Biota also are a relevant matrix for hazardous substances in rivers – agreed, sheet will need development

• Some countries will not have so detailed data for biota as it is specified in sheet – only report what is available

15

Comments: Reporting sheetsComments: Reporting sheetsEMI_SW EMI_SW

• Basically support the approach but needs some further clarification – revised sheet

• E-PRTR should be taken as a basis for reporting on discharges - agreed

• Endorse strongly that each MS can define the regional boundaries for the assessment - reporting at water body level would be problematic - agreed

• Emission categories for point and diffuse sources should be included – added to text

• Parameters and threshold values used for the point sources should be those defined in the E-PRTR Regulation - agreed

16

Comments: Reporting sheetsComments: Reporting sheetsBIO_RIV_INVBIO_RIV_INV

• Proposed indicator is very valuable and represents - on the long term- the way forward a real comparative European wide assessment,

• However, have some doubts about its feasibility on the short term – intercalibration process and need for agreed (long!) taxa lists

• More realistic might be to focus on reporting MS metric results per monitoring station and related national classification results – comments accepted and reporting sheet revised accordingly

17

Comments: Reporting sheetsComments: Reporting sheetsBIO_LK_PHY and BIO_LK_AQU BIO_LK_PHY and BIO_LK_AQU

• Annual biomass and taxonomic composition data will be available for very small subset of lakes but chlorophyll a data will be sampled annually from plenty of lakes – only report what is available

Monitoring stations to obtain Monitoring stations to obtain representative information for SOE representative information for SOE assessmentsassessments

2.1 EEA Assessments• State of, and trends, in the water

environment• Broader assessments of specific water

related issues e.g. eutrophication• Assessment of impact of specific

sectors (e.g. agriculture) on water, perhaps based on conceptual models such as water accounts

22

2.22.2 Information required for SOE Information required for SOE assessmentsassessments

• From waters bodies covering the full range of statuses and impacted by full range of pressures

• Probably from stations included in WFD surveillance and operational monitoring

• Assessments using DPSIR and conceptual frameworks

• EEA will derive proxy pressure information (country validation)

• Data and information will be required from other existing sources, particularly on “D” and “R” aspects of assessments

23

2.32.3 Relationship between monitoring Relationship between monitoring stations, determinands measured at stations, determinands measured at the station and water bodiesthe station and water bodies

• Data will in principle be reported at the station level

• Station level data may then be aggregated spatially and/or temporally in ways appropriate for the assessment being undertaken e.g. at water body level

• Spatial aggregation in coastal and marine waters, and in groundwater

• Number of different relationships between monitoring stations, quality elements measured at the station and the water bodies they represent

2.32.3 Relationship between Relationship between monitoring stations, determinands monitoring stations, determinands measured at the station and water measured at the station and water bodiesbodies

• Reporting at station level will ensure maximum flexibility in how data are subsequently compiled, aggregated and analysed by the EEA

• Need supportive and interpretative information on how stations relate to water bodies and groups of water bodies
