Did you know that part of the medicines we use eventually end up in our rivers through the toilet? According to the new EU directive, urgent action is needed to ensure that treated wastewater does not further pollute the environment – especially in sensitive areas such as the Mura–Drava–Danube UNESCO Biosphere Reserve.
Why is this important?
Small streams and watercourses receiving treated wastewater have such a low water flow that they cannot sufficiently dilute possible micropollutants – such as pharmaceutical residues. These substances can harm aquatic life and even threaten our drinking water sources.
What are we doing?
Within the Slovenian–Hungarian project, we are monitoring 5 wastewater treatment plants and several small watercourses in the middle section of the Mura River. Through monthly sampling, we analyze pharmaceutical residues in raw and treated wastewater, as well as in receiving watercourses, while also testing new treatment solutions in laboratory experiments.
In the first half year, we have already completed:
- A study on pharmaceutical consumption habits and environmental impacts
- A joint sampling and technological plan
- A list of indicator compounds for measuring the efficiency of wastewater treatment
The goal?
To develop a strategy and technological recommendations that support the modernization of wastewater treatment plants, particularly the introduction of a fourth treatment stage – advanced technologies targeting the removal of pharmaceutical residues.
In the long term, this contributes to:
- protecting natural habitats and protected areas
- enabling water reuse
- safeguarding drinking water resources
- preserving human health
This project provides not only environmental but also economic benefits for the region, as it addresses challenges proactively and supports the green transition.
