Low river levels increase infection and injury risks in Serbia, activists warn

The environmental movement Kreni-promeni has warned that low river water levels in Serbia present a significant health hazard, extending beyond typical concerns for navigation and river ecosystems. The reduced water flow impairs the natural dilution of untreated wastewater, leading to a higher concentration of pollutants in the remaining water.

When the river's flow is reduced, the usual dilution effect is absent, leading to an increased proportion of untreated wastewater in the river.

High water temperatures, in some places exceeding 26 degrees Celsius, further exacerbate the problem by promoting the growth of microorganisms and fecal bacteria. Additionally, as water levels recede, the exposed sediment becomes more accessible to people. This sediment can accumulate various pollutants, including heavy metals, over time. When the water is shallow, swimmers can more easily come into contact with the riverbed, stirring up sediment and clouding the water.

In the sediment, various pollutants, including heavy metals, accumulate over time. When the river is shallow, swimmers come into contact with the bottom more easily, and movements stir up the sediment, clouding the water.

Experts also caution about the instability of riverbeds. Currents constantly shift sand and mud, creating unpredictable depths. Areas that were deep previously may become shallow, posing a risk of head and spinal injuries for those who jump into the water without caution. Kreni-promeni advises citizens to swim only at designated beaches where public health institutes regularly monitor water quality. They also recommend showering immediately after swimming and rinsing skin with clean water to remove potential pathogens and impurities.

Currents constantly move sand and mud, so a shallow area one day could become a deep hole the next.
