Standard Test Methods for
Nitrite-Nitrate in Water1

This standard is issued under the fixed designation D 3867; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope*

1.1 These test methods cover the determination of nitrite
nitrogen, nitrate nitrogen, and combined nitrite-nitrate nitrogen
in water and wastewater in the range from 0.05 to 1.0 mg/L
nitrogen. Two test methods2 are given as follows:
Sections
Test Method A—Automated Cadmium Reduction 9 to 16
Test Method B—Manual Cadmium Reduction 17 to 24

1.2 These test methods are applicable to surface, saline,
waste, and ground waters. It is the user’s responsibility to
ensure the validity of these test methods for waters of untested
matrices.

1.3 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 Note 1 and Note 2.
