At a time when water resources become impoverished, it becomes necessary

to keep water supplies under surveillance and to preserve them from any contamination due to either known

pollutants (priority substances listed in the Water Framework Directive) or emerging ones. Pharmaceuticals products

(PPs) are emerging pollutants of interest as they can be still biologically active in waterways and could impact aquatic

ecosystems. They actually contaminate surface and groundwater through direct runoff or discharge of treated sewage

where they are not completely eliminated. Moreover, some compounds have been found in drinking water.
An

integrated approach which considers the whole life-cycle of PPs is proposed to identify the main pressure points and

then to propose actions enable to reduce their occurrence and their impact on the aquatic environment.
For this

purpose, an environmental typology of PPs is developed according to different criteria (treatment plant

characteristics, amount of treated wastewater per inhabitant and per day, origin of the sewage, …) and draw a state

of occurrence of PPs toward these criteria. In this frame, sampling campaigns have been carried out and PPs have

been analyzed by LC-MS/MS. In parallel, several additional treatments (photo-oxidation, adsorption) are tested for

the elimination of PPs residues in environmental waters. All the data will be inter-connected and results will be

scrutinized in order to propose actions for lowering occurrence and the impact of pharmaceuticals in water supplies.

This work is in support for KNAPPE (Knowledge Assessment of Pharmaceutical Products in Environmental waters)

project, funded by European Commission (Specific Support Action - contract n° 036864).
