Many people believe that the most natural thing is that the water in the streams is transparent, but it doesn't have to be. In natural state, the soil components dissolve giving brown color to the water. However, acid rain resulting from contamination acidifies the soil, which reduces the dissolution of soil components and the transparency of streams. In recent years, the decrease in acid rain has contributed to the decrease in soil acidity, observing increasingly brown river and lake waters.
