Detailed explanation-1: -Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers.

Detailed explanation-2: -Merriam-Webster defines the term brackish as “somewhat salty”. Brackish water refers to a water source that is somewhat salty (more so than freshwater) but not as salty as seawater. The exact amount of salinity will vary depending on environmental factors and can not be precisely defined.

Detailed explanation-3: -Brackish water is water that has more salinity than fresh water, but not as much as seawater. Salinity expresses the saltiness or dissolved salt content of a body of water. Technically, brackish water contains between 500 and 30, 000 ppm salt, usually expressed as 0.05-3.0 %.

Detailed explanation-4: -Brackish water or briny water that has more salinity than fresh water, but not as much as sea water. It may result from mixing of sea water with fresh water, as in estuaries, or it may occur in brackish fossil aquifers.

Detailed explanation-5: -Brackish water is a broad term used to describe water that is more saline than freshwater but less saline than true marine environments. Often these are transitional areas between fresh and marine waters. An estuary, which is the part of a river that meets the sea, is the best known example of brackish water.
