Salinity of Water

Salinity is the saltiness or measure of dissolved salt in water.

• 35 g dissolved salt / kg sea water = 35 ppt = 35 o/oo = 3.5% = 35000 ppm = 35000 mg/l
  

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 - 15000 ppm
• brackish water, heavily : 15000 - 35000 ppm
• seawater : 30000 - 50000 ppm (approx. 35000)
  
• brine > 50000 ppm
• Dead sea : 330000 ppm
