The article presents the monitoring data of medicinal substances (PM) in the surface waters of the city of Nur-Sultan and its environs (Republic of Kazakhstan). The results show the presence of carbamazepine and sulfamethaxazole in surface waters. Samples were taken monthly from April to December 2021. Analysis of medicinal substances was carried out using the method of high performance liquid chromatography (HPLC). A possible reason for the presence of medicinal substances in surface waters is their entry with wastewater from the public utility sector of the city of Nur-Sultan into surface sources after treatment.
