Quality of Water (Conductivity or Resistivity)
Ions in the water conduct electricity. Electric current flows easier with high concentrations of ions than it does with low
concentrations. High quality water is low in ion concentration therefore, has a high resistance to electric current. The mea-
surement of electrical conductivity or resistivity provides an accurate measurement of ionic concentration in the water.
