An assessment of contaminations levels of source and tap water in light of the new EU Directive 2020/2184
AI summary Read the abstract
Researchers assessed contamination levels in source and tap water in the context of the new EU Drinking Water Directive 2020/2184, which expanded the list of regulated pollutants including micropollutants. They monitored water quality across treatment stages and identified several contaminants that require attention under the updated regulations. The study underscores the challenge water utilities face in adapting treatment processes to meet evolving standards for emerging contaminants.
Providing healthy and safe water to consumers is a great challenge and responsibility for water supply companies supplying water intended for consumption. Changing legal requirements oblige them to adapt and possibly expand treatment processes to ensure these requirements. A key aspect of ensuring legal requirements and safe water for consumption to consumers is the identification of pollutants, especially micropollutants in water taken for treatment. The studies included monitoring of micropollutants such as pesticides, perfluorinated acids, microplastics, microcystin, PAHs in surface and infiltration water taken for treatment in water treatment plants WTP1 and WTP2, which are the source of drinking water for one of the agglomerations in Poland. In turn, the analysis of the quality of treated water allowed for the assessment of the effectiveness of conventional water treatment processes from monitored pollutants in the tested treatment systems and the assessment of the risks that the presence of these micropollutants in the tested waters carries.

Emerging contaminants migration from pipes used in drinking water distribution systems: a review of the scientific literature
AI summary Read the abstract
Researchers reviewed the migration of emerging contaminants from water distribution pipes into drinking water, focusing on microplastics, bisphenol A, phthalates, and other chemicals. The study found that pipe materials can release these contaminants into tap water, posing potential human health concerns and highlighting the need for better monitoring of distribution system contributions to drinking water contamination.
Microplastics in Drinking Water: A Review of Sources, Removal, Detection, Occurrence, and Potential Risks
AI summary Read the abstract
This review examines how microplastics enter drinking water supply systems, evaluates methods for their detection and removal, and summarizes what is known about their occurrence in treated water. Researchers found that while conventional water treatment removes a significant portion of microplastics, no current method eliminates them completely. The study highlights the need for improved monitoring standards and further research into the long-term health effects of ingesting microplastics through drinking water.
