5.9 Conductivity | Monitoring & Assessment | US EPA

Mar 06 2012 · Organic compounds like oil phenol alcohol and sugar do not conduct electrical current very well and therefore have a low conductivity when in water. Conductivity is also affected by temperature: the warmer the water the higher the conductivity. For this reason conductivity is reported as conductivity at 25 degrees Celsius (25 C).
