    "A measure of a substance ability to transmit an electrical current. Units are typically expressed in millimhos/meter when geophysical measurements are made.",
    "(indicator of saltiness) Electrical conductivity (indicator of saltiness, specific conductivity) is a measure of water's capacity to pass electrical flow. The more ions (molecules with a net electric charge) present, the higher the electrical conductivity of water. Specific conductivity is an indicator of saltiness because when salt is dissolved in water it adds ions to the water. Salty water has higher more ions than freshwater and therefore a higher specific conductivity. Salts (salinity) are minerals that dissolve in water; they can be toxic to freshwater plants and animals and make water unusable for drinking, irrigation, and livestock. Water withdrawals, road de-icing, human and industrial wastewater, fertilizer applications, mining and oil or gas drilling, and repeated use of irrigation water can contribute to high levels of salts."
