1 mg/L = 1 ppm. This is generally true for freshwater and other dilute aqueous solutions. Parts per million concentrations are essentially mass ratios (solute to solution) x a million (106). In this sense, they are similar to wt %, which could be thought of as parts per 250 ppm. Higher concentrations are undesirable because of their laxative effects. Sulfates cannot be economically removed from drinking water.
