Salinity of Water

Salinity of fresh, brackish and sea water

Salinity is the saltiness or dissolved salt content of a body of water.

  • 35 g dissolved salt / kg sea water = 35 ppt = 35 o/oo = 3.5% = 35,000 ppm

Saline in Water

  • fresh water (typical city water in United States) : < 100 ppm
  • water supply typicaly restricted to : 500 ppm
  • fresh water - official salt concentration limits in drinking water US: 1000 ppm
  • typical limit agriculture irrigation : 2000 ppm
  • brackish water, mildly : 1000 - 5,000 ppm
  • brackish water, moderately : 5000 - 15,000 ppm
  • brackish water, heavily : 15,000 - 35,000 ppm
  • sea water : 30,000 - 50,000 ppm (approx. 35,000)
  • brine > 50.000 ppm
  • Dead sea : 330.000 ppm
