ultra fresh water
Water with very low salinity. The salinity is equivalent or nearly equivalent to that of rainwater.
CodeListValue
fresh water
Freshwater refers to bodies of water such as ponds, lakes, rivers and streams containing low concentrations of dissolved salts.
CodeListValue
brackish water
Brackish water is water that has more salinity than fresh water, but not as much as seawater. It may result from mixing of seawater with fresh water, as in estuaries, or it may occur in brackish fossil aquifers.
CodeListValue
saline water
Saline water is water that contains a significant concentration of dissolved salts. Seawater has a salinity of roughly 35,000 ppm, equivalent to 35 g/L.
CodeListValue
brine water
Brine water is saturated or nearly saturated with salt.

acratopegae
From Ancient Greek akratos ( pure, unmixed) and PEGE ( source, fountain). Water with low mineral content or less than mineral water. Translated from : Du grec ancien akratos ( pur, sans melange ) et pege ( source, fontaine ). Qui a, en parlant d'une eau, une faible teneur en sels mineraux ou une teneur moindre que celle d'une eau minerale. http://fr.wiktionary.org/wiki/acratop%C3%A8ge

salt water
Saline water is a general term for water that contains a significant concentration of dissolved salts (NaCl). The concentration is usually expressed in parts per million (ppm) of salt. The salinity concentration level used by United States Geological Survey classifies saline water in three categories. Slightly saline water contains around 1,000 to 3,000 ppm. Moderately saline water contains roughly 3,000 to 10,000 ppm. Highly saline water has around 10,000 to 35,000 ppm of salt. Seawater has a salinity of roughly 35,000 ppm, equivalent to 35 g/L. Technically, brackish water contains between 0.5 to 30 grams of salt per litre?more often expressed as 0.5 to 30 parts per thousand (ppt). Thus, brackish covers a range of salinity regimes and is not considered a precisely defined condition. http://en.wikipedia.org/wiki/Saline_water
