Questionnaires on Water Quality screened so far (1)

• Regional/national: Flemish environmental regulation (Vlarem II)

• EU-Directives on: Drinking water production, Bathing w., Dangerous substances, Fishing w., Shellfish w.;

• EU-Decision on Fresh w.; • (EU-Water Framework Directive)

• pan-European: – Eurostat Urban Audit II, Water Account Quest. – Eurostat-OECD Regional Env. Quest., Inland Waters

Joint Quest.– EEA-EWN Rivers & Lakes– OECD Compendium – OSPAR Riverine Inputs and Direct Discharges

• worldwide: – UNEP-GEMS/Water (+ ESI)– UN Quest. on Environment Statistics

Questionnaires on Water Quality screened so far (2)

HARMONISATION

• Inventory of reporting obligations/ commitments

• Comparison and integration of demands

–> Reporting tables (extended)

• Rationalisation

–> Reporting tables (reduced)

• Terminology – wording & terms; definitions;

descriptions• Codification & classification

– terms: symbols, abbreviations & acronyms

– classifications (+ clusters, subdivisions)– units

RATIONALISATION (1)

• Methodology – approaches, estimations, algorithms– use of standardised methods

• Template format – flow charts– table structure– explanatory notes, footnotes

RATIONALISATION (2)

• Countries / Member states need:– 1 (series of) harmonised guidelines– theoretical background & practical

tools– global vs detailed descriptions– simple (cost-effective, time saving) &

more complex (= accurate) methods
