Industries release off gases like sulphur dioxide and nitrogen oxide in air. When it rains, water droplets react with these, forming acids and carry them down. It causes metal erosion, paints to peel off, freshwater contamination and soil contamination too. These bacteria can control soil and groundwater contamination too by using sulphuric acid as their energy source.
