Respuesta :

Soil can get swept away into the water (by wind, gravity, rain, etc) and can increase the water level of the body of water.

Another thing is that if the soil was infected with pesticides from farmer's crops then the toxins that were in the soil can pollute the body of water. hope this helps!!

Most stormwater that cannot be directed back into rivers or streams is stored in reservoirs for later use being filtered out as either tap water or use for our pluming.
