Zinc enters the domestic water supply from the deterioration of galvanized iron and
brass pipes, and from industrial wastes. Zinc is an essential element for body growth and
development and is an important plant nutrient. Concentrations of zinc above 5.0 mg/L in
drinking water can cause a bitter astringent taste. In the U.S., zinc concentrations may vary
between 0.06 to 7.0 mg/L, with an average value of 1.33 mg/L.
