Water that is saline contains significant amounts referred to as "concentrations" of dissolved salts. In this case, the concentration is the amount by weight of salt in water, as expressed in "parts per million" (ppm). If water has a concentration of 10,000 ppm of dissolved salts, then one percent 10,000 divided by 1,000,000 of the weight of the water comes from dissolved salts.The salinity concentration level used by United States Geological Survey classifies saline water in three categories. Slightly saline water contains around 1,000 to 3,000 ppm.undermount sink
