Potenciális szennyezők monitorozása a Közép-Tisza szakaszon vízhigiénés szempontból

Abstract

In recent decades, the classical bacteriological monitoring of our surface waters has gradually lost its importance, while the increasing water usage (for example for bathing, irrigation, receiving waste water and thermal waters), poses a growing health risk that is further increased by example weather conditions. The majority of wastewater treatment plants regularly struggle with sudden, heavy precipitation, which is received mixed with the wastewater. Most wastewater treatment plants do not have the capacity to store this large volume, so it is often discharged into our surface waters without sufficient treatment. Based on these trends, monitoring-based analysis of surface waters are developing towards a risk-based approach and microbial source tracking. In 2020, based on the monitoring activity carried out on the Middle Tisza section, we detected a pollution source, which could represent a real health hazard under specific hydrological conditions. The investigation also highlighted that knowledge of the appropriate hydrological conditions and water quality may facilitate the appropriate decision-making process.
