Specific Conductance A measure of the ability of water to conduct an electrical current as measured using a 1–cm cell and expressed in units of electrical conductance, i.e., siemens or microsiemens (µS or µmho) at 25°C. Specific conductance is related to the type and concentration of ions in solution and can be used for approximating the total dissolved solids (TDS) content of water by testing its capacity to carry an electrical current. Commonly, the concentration of dissolved solids (in milligrams per liter, mg/L) is from 55 to 75 percent of the specific conductances (in microsiemens, µS). This relation is not constant from stream to stream, and it may vary in the same source with changes in the composition of the water. For comparison, the specific conductance of sea water is approximately 50,000 µS, which is equivalent to a TDS concentration of about 35,000 milligrams per liter (mg/l). (Water Quality) Specific conductance is used in groundwater monitoring as an indication of the presence of ions of chemical substances that may have been released by a leaking landfill or other waste storage or disposal facility. A higher specific conductance in water drawn from Downgradient Wells when compared to Upgradient Wells indicates possible contamination from the facility.
