An expression of the concentration of a material dissolved in water, calculated by dividing the concentration, in milligrams per liter, by the Equivalent Weight of the dissolved material. For example, the equivalent weight of aluminum is 9.0. A water concentration of aluminum of 1.8 milligrams per liter equals an aluminum concentration of 0.2 milliequivalent per liter.
