Monitoring and
reporting @ RWS
WFD Monitoring @ RWS
Marcel Kotte

Raw data  Conversion(s)  Information
• RWS has to report various data because of legislation:
– Water Framework Directive (WFD – 2000/60/EC )
– Bathing Water Directive (76/160/EEC )
– Urban Waste Water Treatment Directive (UWWTD – 91/271/EEC )
– Drinkwater Directive (98/83/EC)
– Nitrates Directive
– Groundwater Directive
- Flood Directive
- Marine Strategy Framework Directive
- Others

And now in slow motion…
• RWS waterbodies (WB)
– One reporting point per WB
– NB: reporting point ≠ measuring point
• Chemical analyses
• Biological analyses

12. Rijkswaterstaat
WFD
• Status and trendanalyses
– Compliance checking
• The WFD is meant to improve the ecological and chemical quality of
waterbodies.

Chemical status; what parameters do we have to
monitor?
• Priority harzardous substances – compliance with EQS
28 april 2015

14. Rijkswaterstaat
Chemical status
• All methods should
meet minimum
performance
criteria
– LOQ < 30% of
EQS
– Relative target
uncertainty at
EQS level: < 50
%
• Year average EQS
• MAC EQS

LoQ = 1/3 * EQS

17. Rijkswaterstaat
Ecological status
• Biological parameters
• ‘Other pollutants’ relevant at river basin level
– Compliance with national EQS
• Physico-chemical parameters supporting interpretation of biological
data
28 april 2015

18. Rijkswaterstaat
Ecological status
• Biological parameters
– Every waterbody is defined by its watertype.
– For each watertype specific environmental quality ratio’s (EQR)
for every biological parameter.
– Each watertype has specific ‘maatlatten’ (yardsticks / EQS)

Ecological status
• ‘Other pollutants’ (chemical parameters)
– Compliance checking to national EQS, bad or good status
• Physico-chemical parameters
– Per watertype different EQR’s and ‘maatlatten’

Ecological status
• Integration of biological status + other pollutants + physiochemical
parameters
