This form of ground water pollution is known as dry deposition. Dry deposition occurs when pollutants in the air, such as chemicals from industrial emissions or vehicle exhaust, settle onto the ground or vegetation without being dissolved in water. This can have detrimental effects on plants and ecosystems as these pollutants can be absorbed by the plants and ultimately enter the groundwater or soil. Dry deposition can also contribute to acid rain and other forms of environmental damage.
