Salt Contamination of Ground Water in South Central Kansas--Part 2 of 5


Salt

When talking about "salt," most people think of table salt or rock salt--sodium chloride--but the term is often used to mean almost any dissolved minerals or inorganic constituents found in water. The salt content of water, also referred to as salinity or total dissolved solids (TDS), is an important water-quality factor. Excessive salt content can make water unpleasant, harmful to plants and animals, or uneconomic to use. In addition, high-salinity water contributes to the deterioration of domestic plumbing and water heaters, and municipal and industrial water-works equipment. Table 1 illustrates how salinity limits the use of water for domestic and agricultural uses.
Table 1--Water-quality threshold indicators for domestic and agricultural uses. Chloride concentration (Cl) is the primary indicator of salinity; corresponding TDS values are approximations for sodium chloride type ground water.
