Salt Index 4. Bicarbonate Hazard 5. Boron Concentration 6. Chloride Concentration 7. Soluble Sodium Percentage 8. Magnesium Hazard 9. Nitrate Concentration 10. Lithium. Criteria # 1. Salinity Hazard or Total [...]
After reading this article you will learn about the meaning and habitats of brackish water. Meaning of Brackish Water: Brackish water is water that has more salinity than fresh water, but not as much as seawater.
