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

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

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

Ecological status

• Biological parameters

• ‘Other pollutants’ relevant at river basin level – Compliance with national EQS

• Physico-chemical parameters supporting interpretation of biological data

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
