Water Quality Monitoring: Conductivity to Salinity Conversion
Salinity
Salinity is a measure of the mass of dissolved salts (ionic constituents) in a given mass of solution and usually expressed as parts per thousand (ppt).
Ions commonly found in water include calcium, magnesium, potassium and sodium cations and bicarbonate, carbonate, chloride, nitrate, and sulfate anions.
Conductivity is a good measure of salinity in water. Other indirect measures are water density, sound speed, and refractive index. All can be used to calculate salinity.
Calculations
- Collect conductivity (μS/cm) and water temperature (C) data.
- Use spreadsheet or calculator to convert conductivity and temperature data to salinity value.
- Conductivity: (μS/cm)
Water temperature: (℃)
Salinity: (ppt)
