Researchers studied the Ciemięga River in Poland to see how human activities affect its water quality. They analyzed water from different points along the river in 2019 and 2020. The results showed high levels of pollutants like phosphorus, nitrates, and bacteria, suggesting pollution from sources like agriculture and wastewater. These pollutants can harm the river's health. To make things better, they recommend reducing pollution from farms, improving water management, and handling waste more responsibly in the area around the river. By taking these steps, the water quality of the Ciemięga River can be improved.
