The Problem – High Levels of Salt

High levels of salt in waters and soils throughout the Central Valley impair water quality, reduce crop production, affect drinking water supplies, and alter ecological functions and habitats. In the Central Valley, salt concentrations are naturally high in some areas and increasing in many others. Salts are concentrated in water and soils by human activities and evaporation. Salts are also added to the Central Valley from imported water supplies. Activities in homes, farms, businesses, cities, and towns all contribute to the salt problem by adding or concentrating salts. Irrigation, food processing, and municipal water and wastewater treatment are just some of the processes that increase the salt problem in the Central Valley.
