Several initiatives end-2017 and 2018 on identification of substances of concern to drinking water resources.
ECETOC role in supporting the development of a science-based framework to assess the potential concern for drinking water resources.
Terms of Reference
- Review current EU legislation pertaining to quality of water sources (GWD, DWD, WFD, Urban Wastewater Directive) as well as other national and international legislation (including US, Canada, Switzerland, Stockholm convention) and associated threshold criteria.
- Assess the appropriateness of the proposed PMT hazard-based approach versus a risk assessment and suitable risk management to guarantee long-term sustainable protection of water sources.
- Review the monitoring data available for levels of mono-constituent substances measured in groundwater and surface water and critically evaluate the currently proposed and eventually revised PMT/vPvM-criteria in the EU.
- Evaluate how and when to consider relevant metabolites in the PMT concept and in the context of protection of water sources via risk assessment.
- Evaluate the relevance and appropriateness of the current mobility criteria (‘M’), and, if necessary, make recommendations for parameters/methods to assess hydraulic transport potential to water sources and consider development of a tiered testing approach.
- Evaluate the appropriateness of the additional T criteria in the PMT concept, in light of the existing ones within the PBT concept, and its relevance to a risk assessment approach.
Timeline and deliverables
The outcome of the work will be an ECETOC Technical Report and/or published article.
It is foreseen that the Task Force will complete its work within 12 months
A Kick-Off Meeting took place at ECETOC on 18th January 2019
