Pollen? Hardly! The pH of river water is affected by a variety of factors: dissolved CO2 from the air (making it slightly acidic), organic acids from the soil, and by dissolved minerals such as calcium carbonate.

Low pH in river water can be caused by acid rain, which occurs when pollutants like sulfur dioxide and nitrogen oxides from sources such as industrial emissions mix with rainwater. Other potential factors include natural processes such as decomposition of organic matter and the presence of certain rocks or soils that release acidic compounds into the water.
