How Do You Measure Conductivity In Water?
Conductivity is a measure of how well a material conducts electricity. In water, electricity is conducted by the available ions, or electrolytes, dissolved in the water. Thus, measuring the conductivity of water from different sources can indicate the concentration of electrolytes therein. For this reason, conductivity can also be a measure of water quality, as many minerals and runoff from fertilizers produce ions that increase conductivity. Measure the conductivity of water from several sources to determine how much they vary in ion content. Select several locations from which to collect water. To do a thorough environmental survey, collect the water from several locations in the same waterway. Label vials with date, time, location, and collection depth before collecting. Do not put the labels on the vials. Collect samples by dunking the vials in the waterway. Allow the flow of water to resume before removing each vial and capping it. Wipe the vials dry and apply the labels. Allow al
