Summary of the Action:
Three of the major concerns for European waters are anthropogenic nutrient enrichment, chemical and biological contamination, and sufficient, safe and good chemical and microbiological quality drinking water for EU citizens. The overall goal of this action is to provide methodologies, assessment tools and assessments of the exposure of EU waters to contaminants through experimental measurements and models. This will contribute to the understanding and quantification of the fate and effects of contaminants (chemical, biological) in inland, coastal and drinking waters of the MS and CC, and to assess how nutrient enrichment interacts with chemical and biological stressors. Methodologies for the assessment of the microbiological quality of drinking water and ecotoxicological quality of surface water will be developed and implemented. Rationale Release of chemical substances significantly impacts European waters. Impacts are both direct and indirect, through degradation products, acute and/or chronic toxic toxicity, and/or long-term effects via bioaccumation in aquatic food chains.
Pollutants may accumulate in aquatic food chains and/or pollute our drinking water. As the number of substances is large and measures to reduce emission are costly and time demanding, there is a necessary prioritisation of the efforts through risk assessment studies requiring exposure data, which is both scarce and difficult to obtain. Furthermore, pathways of contaminants from the emission source to the receiving waters are not always clear, in particular for contaminants emitted from diffuse sources. Products used in water supply systems may release substances into drinking water and source water disinfection gives rise to problematic by-products. Furthermore, the health effects of microbial contamination in bathing and drinking water may be more pronounced and severe than previously thought, magnified by episodic events such as floods. Microbial growth in water supply systems depends on the materials used, the design of the system, and leakage. The development of harmonised methodologies to detect microorganisms and pathogens, as well as the ecotoxicological quality of surface waters are urgently needed, especially in collaboration with Candidate Countries.
