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.
