On March 27, 2026, within the framework of pedagogical practice, Master’s students of the Department of Chemical Physics and Materials Science of the Faculty of Chemistry and Chemical Technology at 91��ý Kazakh National University – Allabergen A., Berenkyzy D., Yesirkep N., Yermagambetova A., Zhaxybayeva U., Iskakov A., Makhmudova A., Muzarapsha N., Nurlankyzy Sh., and Yuldashev N. – conducted an open educational session for 3rd-year undergraduate students. The topic of the event was “The Main Environmental Problem of Kazakhstan: Water Pollution and Methods of Its Purification.”

The purpose of the event was to highlight the profound importance of ecology, which is an integral part of the UN Sustainable Development Goals (SDGs), by examining the problem of water pollution within the territory of Kazakhstan.

During the event, the organizers emphasized that water is the most important natural resource and the foundation of life. However, the level of pollution in rivers, lakes, and groundwater is currently increasing significantly. Particular attention was paid to sources of pollution such as industrial waste, agricultural chemicals, and domestic wastewater, which negatively affect the environmental situation.

In the theoretical part, students were provided with information about the types of water pollution (chemical, biological, and physical), as well as their impact on human health and the environment. The environmental disaster of the Aral Sea was considered as an example, including the causes of its desiccation and its consequences for the region.

The event then continued in an interactive format: students were given group tasks where they discussed various water purification methods, including mechanical filtration, adsorption, chemical, and biological treatment. Particular interest was shown in purification methods using carbon-based sorbents.

The practical part of the event included a demonstrative experiment on water purification using a homemade filter. The filter was constructed from available materials (a plastic bottle, layers of sand, activated carbon, gravel, and cotton). Contaminated water was passed through the filter, and as a result, students observed a significant improvement in its clarity and quality. This experiment demonstrated the effectiveness of simple water purification methods in practice and generated great interest among the participants.

To reinforce the acquired knowledge, a quiz was conducted, during which participants answered questions related to the protection and rational use of water resources. The most active students were awarded.

In conclusion, it was noted that maintaining the cleanliness of water resources is an important responsibility of every individual. The development of environmental awareness and a responsible attitude toward nature play a key role in ensuring a sustainable future.

The event was conducted at a high level and contributed to increasing students’ environmental literacy, as well as fostering their responsibility for the state of the environment.
