> 0,1 µg/l

Attention!(Oasen)

>1 µg/l

Exemption needed from regulator

> 1 µg/l or > 0,1 µg/l Exemption needed from regulator

When is action needed?

(Provisional) Drinking water standard ≈ 1 µg/l or unknown Very high concern

> 0,1 µg/l High concern

EDTA / TFA / MTBE / 1,4 Dioxan / PFOA / PFOS / GenX /

Pyrazole (vPvM)

MTBE / 1,4 Dioxan / PFOA / PFOS / GenX / Pyrazole (vPvM & PMT)

Actions by Drinking Water Supply Companies

 Monitoring & contacting sources (discharges) of micro pollutants & regulators

 Lobby for improving better regulation (EU / National)

 Lobby for improved implementation of regulations

Prevention (with RIWA / IAWR / Vewin / Eureau)

Research and implementing improved purification

Discussion with regulators and industry about

Prevention example 4: Improving regulations

 Improving & support for WFD-directive

 Threat for drinking water as criterium for admission chemical substances

 Support for vPvM & PMT criteria in REACH SVHC

RIWA / IAWR/ Vewin / Eureau

RIWA / Vewin & Ministry Of

Infrastructure and Water Management

Provinces / local regulators

 Improving legislation on discharge of SVHC substances upstream of drinking water intakes

 Improving implementation and knowledge of legislation

Research on improved purification

Bottom line

Prevention is better than cure
