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.
