👉 Brackish is a scientific term that refers to a type of water that is typically found in bodies of saltwater, such as rivers or lakes. It is characterized by its high salinity (salt concentration) and low oxygen content compared to fresh water. Brackish water can be found in regions with high levels of pollution, industrial activities, or simply due to the presence of certain types of bacteria or algae that have adapted to living in an environment where salt concentrations are high.
