TYPES of WATER
- FRESH WATER: IS ANY WATER FOUND, THAT IS NOT FROM THE SEA
- Around 10,000 of the world’s 25,000 known fish species live in fresh water. An average of 300 new freshwater fish species are discovered every year
- Wetlands around the world provide goods and services to people worth an estimated US$70 billion a year
- Freshwater ecosystems have a higher concentration of species relative to their area than land or sea
- BRACKISH WATER : IS WATER THAT HAS MORE SALINITY THAN FRESH WATER,BUT NOT AS MUCH AS SALTWATER.
- It can result from mixing of seawater with fresh water, as in estuaries, or it may occur in brackish fossil aquifers
- The word comes from the Middle Dutch root "brak," meaning "salten" or "salty"
- Certain human activities can produce brackish water, in particular certain civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming
- Brackish water is also the primary waste product of the salinity gradient power process
- Brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment
