Romashka [77]

Answer: An erosion of soil which enters waterways

Explanation:

Acidic water is more poisonous to human, animal and plant life so if acidic water were to wash into a river that humans drink, the health risks posed to those humans would increase.

If there were plants and animals connected to the river, the risks to them would increase as well and disrupt their life cycle.

Acidic water does not make water more or less capable of soil erosion so the water being acidic would not contribute to soil erosion.
