WebWater quality standards Electrical conductivity is a measure of the saltiness of the water and is measured on a scale from 0 to 50,000 uS/cm. Electrical conductivity is measured in microsiemens per centimeter (uS/cm). Freshwater is usually between 0 and 1,500 uS/cm and typical sea water has a conductivity value of about 50,000 As conductivity ranges determine how much electricity can pass through the water, different conductivity ranges have specific uses. 1. 0-800 µS/cm:Drinking water supplies, irrigation, and all livestock. 2. 800-2,500 µS/cm:Irrigation, all livestock, and sometimes drinking water (lower conductance ranges are … See more Conductivity ranges tell us a lot about the quality of waterbecause it is a direct measurement of how many pollutants and contaminants are in the water and an indirect measurement … See more Freshwater and seawater have typical ranges, yet, there is no set standard for the conductivityof water because of the effect surrounding environments have on electrical conductivity. Despite the lack of set standards, there … See more Conductivity ranges are best measured directly using a conductivity probe with a conductivity meter/sensor.
