FRESHWATER

Water containing less than 1 mg/l of dissolved solids of any type. Water sources can only be considered freshwater when they do not include brackish or seawater. These sources include rivers, lakes, streams, icebergs, ice sheets, ponds, bogs, and even underground water that is referred to as groundwater. Freshwater is not exactly similar to drinking or potable water. Freshwater contains a minimal amount of dissolved substances such as saline and is generally the opposite of salty water found in the sea.
