- According to calculation methodology


Relation Key Pressure / Representative Impact

Identified Key Pressures:Punctual: organic and nutrientsDifuse: nitrogen, biocides, contaminated soilExtracctionsRegulationHydromorphological

Representative Impact:BOD5 (mg/l) and P total (mg/l)


Threshold proposal: Good StatusThe criteria taken into account are the following:- Provisional value- Current regulations- Same threshold for all ecotypes- Coherent value with reference conditions

Values to revise depending on ecotype and reference conditions

6.- Conclusions


Conclusions

•Need to carry out key pressures analysis -representative impact to analyse POM

•Complexity in good status threshold definition andneed of intercalibration

•Usefulness of modelation in GIS for POM effectivenessanalysis: Serpis pilot case

•Quality National Plan: Basic Measures

•Need for analysis methodologies:•Complementary measures - less rigourous objectives.

•Exception Possibilities: costs out of proportion
