Significance and Use

Zinc is an essential and beneficial element in body growth. Concentrations above 5 mg/L can cause a bitter astringent taste and opalescence in alkaline waters. The zinc concentration of U.S. drinking waters varies between 0.06 and 7.0 mg/L with a mean of 1.33 mg/L. Zinc most commonly enters the domestic water supply from deterioration of galvanized iron and dezincification of brass. Zinc in water also may result from industrial water pollution.3


1.1 These test methods cover the determination of zinc in water. Two test methods are given as follows:

Test MethodConcentration RangeSections
A-Atomic Absorption, Direct0.05 to 2 mg/L
B-Atomic Absorption, Chelation-Extraction20 to 200 g/L

1.2 Either dissolved or total recoverable zinc may be determined.

1.3 These test methods have been used successfully with reagent grade water. See the specific test method for applicability to other matrices. It is the user's responsibility to assure the validity of these test methods in other matrices.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 6 and Note 5, Note 8, and Note 13.

1.4 Two former colorimetric test methods were discontinued. Refer to Appendix x1 for historical information.
