Water pollution by power plants - Blogger

2008-02-11· Power plants use water for cooling. The quantity of water required by any fossil fuel fired power plant is huge - up to a billion gallons each day! As this water is discharged back to the river, thermal (heat) pollution occurs. This huge quantity of warmer water can create ice-free pockets in winter of cold countries, which can attract and then trap many species when the flow slows or stops ...
