Dissolved oxygen and water quality
WebAs water temperature increases, the amount of oxygen the water can hold decreases. Likewise, as salinity increases, less oxygen can be dissolved into the water. At greater pressures, water can hold more oxygen. For example, more oxygen can be held in water (of equal temperature and salinity) in Miami than at the much higher altitudes of Denver. WebThe water quality index is calculated based on measured values for each of five parameters: Temperature, Biological Oxygen Demand, Total Suspended Solids, …
